Lithium Polymer Batteries – The Ultimate FAQ Guide

The advanced technology requires electronic gadgets such as laptops and smartphones to run smoothly with high-quality batteries.

To fulfill this need of the hour, TLH manufactures high functioning Lithium Polymer batteries in different sizes and shapes suitable for every gadget out there.

This guide has been written to help you understand all the information about Lithium Polymer batteries before actually buying so that you make the right decision.

1. What is a Lithium Polymer Battery made of?

Lithium Polymer batteries are pretty advanced as compared to other ones in terms of size, functioning, and efficiency.

The main difference in its composition, which makes it different, is using a semisolid gel-like material as an electrolyte instead of a liquid one used in normal cells and batteries.

This semi-solid gel is made up of polymers and helps in decreasing the size plus weight of the battery.


                                        Figure No: 1 Lithium Polymer battery

The electrolyte does not have to be semisolid always; it can be dry and porous, too, depending on the type of Lithium Polymer battery you want to manufacture.

The basic composition is divided into four main parts: a positive electrode, negative electrode, separator, and electrolyte.

The separator, often composed of polymer makes the cell a polymer cell even if the electrolyte being used is a liquid.

2. What is the function of Lithium Polymer batteries?

Lithium Polymer batteries’ general and overviewed function is to provide energy or current supply to the device it has been attached to.

All four main parts of the battery start functioning altogether. The first two parts, named anode and cathode, collect and store the lithium.


                                          Figure No: 2 Lithium Polymer battery function

The electrolyte, made of Polymer, transports the ions from anode to cathode, making them pass through the separator.

The current after being collected goes towards the device and runs it.

Lithium Polymer batteries are compact and slim and are known for providing a lightweight current delivering process.

3. What is the lifespan of a Lithium Polymer Battery?

A manufacturer can only estimate a Lithium Polymer battery’s lifespan as its health and functioning depend on various circumstances.

With proper care and precautions, a lithium Polymer battery can last up to 3,4 years.


                                          Figure No: 3 Lifespan of Lithium Polymer Battery

Misuse of the product can reduce the amount of time it is supposed to function properly.

Natural malfunction and drastic circumstances can also affect the estimated lifespan of a Lithium Polymer battery.

Continuous or excessive use can affect the desired high-end functioning, but the battery would still work even if not up to its highest capacity.

However, a decent amount of usage with consideration can even broaden a Lithium Polymer battery’s life health.

4. How dangerous can Lithium Polymer batteries be?

Lithium Polymer batteries can be a threat to a person’s body and can damage the surrounding surface area of a place these would be getting charged.

A Lithium Polymer battery while being charged should never be left alone to prevent any kind of destruction.

Overcharging can cause the Lithium Polymer battery to burst or explode, harming the person who would be nearby at that time.

It can severely burn and hurt the human body if it explodes, as the explosion would cause a fire.

Careful use of the product would never cause any unfavorable incident as prevention is always better.

Lithium Polymer batteries are soft and smaller in size, and these attributes make them a tad bit hard to handle.

Punching nails in the batteries for fun can cause the Lithium Polymer battery’s outer bag to rupture, which results in the leakage of electrolyte.

The electrolyte or all the other elements present inside a Lithium Polymer battery are toxic for the human body and can risk health.

The rupturing of the bag also causes the insides of the battery to react with oxygen which ultimately results in explosion and destruction.

You should not leave your Lithium Polymer battery unattended, especially when it is being charged, so that it may not get overcharged and cause damage.

5. How are Lithium Polymer batteries better than others?

Lithium Polymer batteries are of advanced technology preferred by this generation more than any other type due to various reasons.

Every product surely has its advantages and limitations, but the advantages of Lithium Polymer batteries are so promising that they overpower the limitations.

The main attribute and advantage it offers is its size-friendly nature, allowing the companies a broader room to experience more ways of molding the electric devices.

The lightweight of the product makes it suitable for aircraft and handy devices. Nobody likes to hold heavy gadgets in their hands making themselves tired and weary.

                                                     Figure No 5 Lithium Polymer Batteries Vs other batteries     

                               Figure No: 5 Lithium Polymer Batteries Vs other batteries

The gel-like electrolyte used for the Lithium Polymer batteries gives the manufacturers the power to mold it in various ranges and forms.

Lithium Polymer batteries can store more energy than other types of batteries, such as Nickel batteries.

Lithium Polymer batteries are strong and do not get damaged easily, you would be throwing them around, making them fall, have heavy objects placed on them, and still will not rupture.

The solid and bearable nature, being size and shape-friendly, lightweight, and being able to provide more energy makes the Lithium Polymer batteries better than other ones.

6. Where do Lithium Polymer batteries get used?

Lithium Polymer batteries’ usage has increased in today’s world with the gradual advancement of technology and electronic devices.

In older times, Lithium Polymer batteries were famous for being used in aircraft and remote-controlled cars or toys in general.

Now, the invention of many new electronic gadgets has taken place, which provides a broader room for Lithium Polymer batteries’ usage.


                                           Figure No: 6 Applications of Lithium Polymer Batteries

Lithium Polymer batteries are used in laptops as these are generally thin computers and require a source of energy that is lightweight as well as reliable.

The trend of cell phones has gone towards being slim, also known as smartphones.

These require the installation of Lithium Polymer batteries as an energy carrier to keep up with the advanced shape.

Lithium Polymer batteries are also used to manufacture power banks that are known as small energy-carrying devices to charge your smartphones anywhere.

The search for finding a less harmful way of consuming nicotine has brought humankind to invent electronic cigarettes etc these require Lithium Polymer batteries for their manufacturing.

Moreover, lithium batteries can be used in all electronic portable devices, which require small-sized and lightweight batteries.

7. How can you maintain Lithium Polymer batteries?

The maintenance or proper use of a Lithium Polymer battery may help increase its health lifespan and work efficiently.

Each product demands decent usage for it to work perfectly, and doing the other way around will result in unfavorable conditions.

A Lithium Polymer battery’s normal lifespan is 2 to 3 years, but careful usage can prolong it up to 4 years.

The lifespan depends on the number of cycles a battery can perform, 2 to 3 years lifespan means the battery can perform at least 500 cycles.

One cycle includes complete charging of the battery, then discharge and recharge again.

Check the health of the battery during the start of the usage to notice the gradual change in its health with the passage of time and usage.

Always charge the battery at least 50 percent before using the respective device; this prevents the battery from wearing out.

Do not expose the batteries to a temperature above 60 degrees; this can cause the battery to explode.

Not using the batteries for a long time can affect their health; do not let them wear out by not using it.

If a battery has not been used for six months, it is advised to throw it out and replace it with a new one.

Keep the batteries away from children.

Keep the batteries away from exposure to fire and water.

8. How can you repair Lithium Polymer batteries?

Sometimes one of the cells inside the battery gets damaged and stops working, which makes the owner think the entire battery has become useless now.

You can open the Lithium Polymer battery with care and precautions, remove the damaged cell and replace it with the new one.

Replace that specific damaged battery with a fully functioning new one and get your battery working again.

Freezing the battery for 24 to 48 hours and then recharging it might restore the Lithium Polymer battery’s health percentage.

Discharge the battery fully, recharge it, discharge again, and fully recharge again, this process results in enhancing the battery’s health.

These ways can help you restore a slightly damaged Lithium Polymer battery.

9. What is the charging process for Lithium Polymer batteries?

The disruption may result in explosion and eruption of the battery as the Lithium Polymer batteries are highly sensitive toward their charging process.

The batteries must not be charged in a high-temperature environment; the temperature must not be less than 0 degrees and more than 45 degrees.

The charger of the battery should be made according to the type of the battery so that the battery gets an estimated voltage, not less, not higher.

Charging the Lithium Polymer battery with a charger not specifically designed for it can be highly dangerous and will damage the battery.

Estimate a proper time for the charging of the battery and do not charge it more than that to prevent any kind of destruction and damage.


                                            Figure No: 9 Charging Lithium Polymer Batteries

Lithium Polymer batteries should not be charged near the fire, water, or at humid places.

It is suggested to keep a fire extinguisher or dry sand near your battery while charging it for safety purposes.

Do not charge your Lithium Polymer battery inside a heated vehicle; it can damage the product.

10. What are the precautions of Lithium Polymer batteries?

Lithium is a very reactive material and gets on fire quite easily, so it is mandatory to keep it at a place with low temperatures.

Fire extinguishers should be present at all times in case things go bad, you can control the situation quickly and prevent further damage; you can keep dry sand as well.

Check the batteries properly for any leakage or breakages before buying.

Discard the Lithium Polymer battery right away if it shows signs of breakage of bag or leakage of electrolyte or any other liquid.

Do not let the battery get overcharged or extremely hot, it can cause the battery to swell and ultimately explode.

Discard the battery if you notice swelling on the surface of it.

Keep the Lithium Polymer batteries away from children and pets at all costs to keep them safe.

Make sure not to let the charging battery stay under your pillow or near your bed while sleeping for your safety.

11. How can you revive a Lithium Polymer battery?

The process of revival is not that complicated and you can try it out by yourself at home.

Ensure your safety before actually getting into the proper process by wearing gloves, these can protect you from sharp objects and the chances of getting bruised will be less.

Inspect the batteries thoroughly and look for any swollen parts; these can be very dangerous, can rupture at any moment causing serious damages.

A home knife can be a suitable tool for it, too, a tester to check the current flow, a multimeter to read the voltage level, and a balance charger for the battery’s revival.

Open it up with the help of the tools you gathered, remove the cells you need to revive from the body, and put them aside.

Now check and thoroughly inspect the cells, their voltage capacity, battery lifespan, and health, how many cycles these have been completed, and how much more they can do.

For this, you need the balanced charger or any charger which offers the option of reviving dead batteries or cells.

Charge the cells with a low voltage supply at first and gradually charge it fully, take it off from the charger and keep it as it is for a night or two.

If the discharging level was low and it still kept some amount of current stored in it, the battery has been revived and can perform its work for some more time.

Charging, discharging, and recharging completes one cycle of a battery, repeating this cycle 2 to 3 times can revive a battery.

12. What is the difference between Lithium Polymer and Lithium-ion batteries?

Lithium-ion batteries have the basic composition, almost similar to any other normal type of battery, it consists of an anode and a cathode generally known as positive and negative electrodes.

The third part of a Lithium-ion battery is the electrolyte, which is mostly liquid, the electrolyte is the part that mainly differs Lithium Polymer batteries from Lithium-ion batteries.

Lithium-ion batteries are cheaper than Lithium Polymer ones that is why their use is feasible and is still going strong in the market.

Lithium-ion batteries have more capacity in terms of storing current and are cheaper than Lithium polymer batteries.


                                    Figure No: 11 Lithium Polymer Vs Li-ion batteries

Lithium Polymer batteries have a chemical composition, almost the same as Lithium-ion batteries do.

They have one positive electrode, a negative electrode, a separator, and an electrolyte.

The electrolyte is not in liquid form, it is mainly of three types.

Dry, porous, and a semi-solid gel-like electrolyte.

Lithium Polymer batteries, including gel-like electrolytes are the most common and advanced ones.

The electrolyte makes the battery extremely lightweight, handy, and feasible.

But the difference it makes from Lithium-ion batteries is that they are quite expensive which makes the whole device they are being used in, expensive too.

13. Can a Lithium Polymer battery get caught on fire?

Their packaging is extremely small and compact leaves less room for the heat and temperature to move around and not cause any serious problems.

It also leaves almost no room for excessive or even a tad bit more current going inside it.

When any of these things happen, the Lithium Polymer batteries are bound to explode and cause damage to the surroundings.

Overcharging is the most common cause of Lithium Polymer batteries getting caught on fire.

Using the wrong kind of charger for charging your Lithium Polymer battery can also cause a short circuit or fire.

Lithium itself is a highly reactive material, which makes it feasible for battery manufacturing and energy storage, but at the same time, the highly reactive material can cause fire easily.

Charging the Lithium Polymer batteries with a high-temperature environment can also be the reason for it causing fire or exploding.

14. How do you replace a Lithium Polymer battery?

No matter how expensive or high-quality batteries the manufacturer has provided you with, it is bound to stop working at some point.

This is the point where you are supposed to replace the weary and non-functioning Lithium Polymer battery with a new, fully functioning one.

Manufacturers like TLH offer the service of providing your desired Lithium Polymer batteries at your doorstep.

The process is not that complicated, ensure your safety first, by wearing gloves and protective eye goggles.

Open up your device with which the damaged battery is attached.

Remove the battery carefully with the help of a sharp home knife or scalpel, separate the nuts and bolts with a screwdriver.

Discard the damaged piece or recycle it.

Inspect the new Lithium Polymer battery for any leakage or breakage, do not insert it without the safety inspection.

The battery should be fully charged first before the actual usage.

15. How many types of Lithium Polymer batteries are there?

The composition of the Lithium Polymer battery includes three different types.

Instead of using a basic liquid electrolyte, Lithium Polymer batteries go with something solid.

The first type includes a negative electrode, a positive electrode, and a dry electrolyte.


                                          Figure No: 14 Types of Lithium Polymer Batteries

The second type of Lithium Polymer battery includes a composition of an anode, a cathode, and a porous electrolyte.

The third type of Lithium Polymer battery comes with a composition almost the same as before, such as a negative electrode, a positive electrode, and an electrolyte made up of gel-like material.

This third type of Lithium Polymer battery is the most common and feasible one and is being manufactured on a high level.

16. What is the temperature range of Lithium Polymer batteries?

Lithium Polymer batteries are suggested to be charged at room temperature always, room temperature is considered to be the most feasible for these batteries.

Room temperature is the one which is not too high nor too low, that is 20 to 35 degrees.

But a temperature range from 5 degrees to 45 degrees is considered to be the final for Lithium Polymer batteries.


                              Figure No: 15 Temperature range of Lithium Polymer Batteries

Anything less than 5 degrees would be too low for Lithium Polymer batteries and their discharging process would be affected.

More than 45 degrees would be too hot for Lithium Polymer batteries; this high temperature not only affects the battery’s health but can also result in the explosion of the battery.

Thus, you should always use and charge your Lithium Polymer battery within the suggested temperature range that is from 5 to 20 degrees.

17. Where can you buy Lithium Polymer batteries in bulk?

Not every manufacturer out there is manufacturing the product of your desired quality, plus the shipment and packaging demand proper safety, or else the batteries can explode meanwhile.

Tianhile Technology Co provides you with the most promising and high-quality Lithium Polymer batteries, that too in bulk.

Their customer service is top-notch, they accommodate their customers’ needs and have to motto to deliver the exact product a buyer demands.

18. Where can you buy Lithium Polymer batteries at reasonable prices?

Lithium Polymer batteries are so expensive because the electrolyte getting used in these is mostly of a gel-like material, which gives these the liberty of being lightweight, handy, and moldy.

The product which is already famous for being expensive gives manufacturers all around the world a chance to manipulate the price even more.

Thus each manufacturer offers a different price, making it even more difficult for a buyer to decide whether to go for a higher-priced one or not.

Chinese manufacturers provide the best services in terms of Lithium Polymer batteries, such as Tianhile Technology Co, a China-based company that provides its customers with top-quality products that too at affordable prices.

19. How fast can Lithium Polymer batteries be delivered to you?

The timing required for the delivery or shipment of Lithium Polymer batteries depends on several things.

It can be delivered swiftly and in no time if the manufacturer lives in the same city as you.

However, the delivery process will require more or less some weeks if you have ordered the Lithium Polymer battery from some other country, but the country is nearby.

The shipment by boat will take months and months till the Lithium Polymer battery finally reaches your doorstep.

On the other hand, delivery by air will take not more than a few days even if the parcel is coming from a country far away from you, but this process is more expensive than others.

20. What are the shipment methods for Lithium Polymer batteries?

The shipment requires specific conditions, precautions and permissions; without these the government does not allow the shipment process of Lithium Polymer batteries to take place.

Lithium Polymer batteries can be shipped by air but the batteries have to be protected by a specific protective packaging, mainly manufactured for Lithium Polymer batteries to prevent any drastic incident.

Lithium Polymer batteries can be delivered by road on trucks, vans, or containers if you work according to all the rules that are set by the government.

Shipment by sea has its limitations; lithium is a highly reactive material, and keeping it safe and protective on a boat for several months is not an easy task.

Thus this process has not been encouraged as much as the rest of the methods.

21. What are the purchasing methods for Lithium Polymer batteries?
