1. Portability

First of all, you need to know that lithium polymer batteries generally use solid or gel electrolyte, while lithium ion batteries generally use liquid electrolyte, which makes lithium polymer batteries can be constructed more flexibly, you can make them into any shape through special manufacturing methods, for those devices that need specific shapes, lithium polymer batteries this characteristic provides a lot of convenience.

Secondly, the solid or gel electrolyte in lithium polymer is much lighter than the electrolyte in lithium ion batteries, so the total weight of lithium polymer batteries is lighter than lithium ion batteries, which makes lithium polymer batteries much easier to transport and carry, and thanks to this feature, lithium polymer batteries are widely used in such fields as drones and wearables, which shows that lithium polymer batteries are superior to lithium ion batteries in terms of portability. This also shows that lithium polymer batteries are better than lithium ion batteries in terms of portability.

2. Safety

The safety of lithium polymer batteries is higher than that of lithium ion batteries to a certain extent. Thanks to the solid electrolyte or gel electrolyte used in lithium polymer batteries, this kind of electrolyte is not as easy to leak as liquid electrolyte, so the risk of fire due to liquid leakage in lithium polymer batteries is greatly reduced.

Of course, generally speaking, lithium-ion batteries are equipped with a mature battery management system, which can greatly reduce the occurrence of overcharge, overdischarge, short circuit and higher operating temperatures and other abnormalities, so you don’t need to worry too much about the safety of lithium-ion batteries.

3. Cycle life

Due to the internal structure of lithium-ion batteries and lithium polymer batteries, materials and manufacturing process differences, which leads to lithium polymer batteries cycle life is lower than lithium-ion batteries, which you need to pay attention to, if you want a longer service life of the battery, choose lithium-ion batteries are obviously better than choosing lithium polymer batteries.

4. Battery Charging and Discharging Characteristics

You should know that the liquid electrolyte is more conducive to the rapid movement of lithium ions between the positive and negative electrodes, so lithium-ion batteries will be faster than lithium-polymer batteries in the charge and discharge speed, so for the charging speed of the higher requirements of the scene, such as car batteries, etc., you’d better choose the lithium-ion batteries, it will greatly save your charging time.

5. Cost

Obviously, the cost of lithium-ion batteries is much lower than lithium polymer batteries. First of all, lithium-ion batteries have been commercialized as early as 1991, after decades of development, lithium-ion battery manufacturing process has been very mature, lithium-ion battery production line automation is much higher than lithium-polymer batteries, which makes lithium-ion batteries manufacturing cost is much lower than lithium-polymer batteries, naturally, lithium-ion batteries cost less than lithium-polymer batteries.

Secondly, the solid or gel electrolyte used in lithium polymer batteries, as well as the flexible packaging materials of lithium polymer are more expensive, so the material cost of lithium polymer batteries is higher, so the cost of lithium polymer batteries is higher than lithium-ion batteries, which you need to pay attention to before selecting the right battery.

6. Energy density

The energy density of lithium polymer batteries is usually lower than lithium-ion batteries, which means that lithium-ion batteries and lithium polymer batteries in the same weight and volume, the former can store more energy, this is because the electrolyte inside the lithium-ion batteries can hold more lithium ions than solid or gel electrolyte, which leads to the energy density of lithium-ion batteries is higher.

7. Environmental protection

In terms of environmental protection, lithium polymer batteries to a certain extent better than lithium-ion batteries, this is because the electrolyte inside the lithium-ion battery is harmful, and recycling lithium-ion batteries need to remove the battery’s metal casing, which may lead to the dispersal of harmful substances. However, lithium-ion batteries have a more complete battery recycling process, you only need to strictly follow the battery recycling process for battery recycling, basically will not cause much harm to the environment.

8. Summary

Lithium polymer and lithium ion as a battery material have a wide range of applications, lithium polymer compared to lithium ion later used in the field of batteries, the two battery materials in different aspects of the strengths of each, the following is a specific comparison of the two battery materials, you can better understand the two types of battery materials, you can make the right choice according to their own situation, it is still very important for you.
