Why do mobile power sources start using lithium polymer batteries?

In the past, all mobile power sources used 18650 batteries. 18650 batteries have gained the favor of many brands due to their light weight and large capacity. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power sources start using lithium polymer batteries?

Lithium polymer battery

一、What is a lithium polymer battery

Lithium polymer battery is a new type of lithium battery with high density, using collagen fiber polymers as the electrolyte. It can be made into batteries of various shapes and capacities according to equipment requirements, with a minimum wall thickness of 0.5 mm, without battery charging memory.

二、What are the advantages of lithium polymer batteries compared to 18650 batteries?

1. The 18650 battery is an ordinary lithium battery that uses a liquid electrolyte, while the lithium polymer battery uses a gel sensitive electrolyte, which is not prone to liquid leakage.

2. Lithium polymer batteries have a high relative density and strong ductility, and can be made into the shapes required by their customers based on mobile power requirements. Mobile power supplies with equal capacity are more lightweight.

3. When the 18650 battery experiences overcharging, short circuit faults, and other situations, it is likely to cause an explosion in the mobile power supply, while lithium polymer batteries are not easy.

三、Why do mobile power supplies use lithium polymer batteries?

It is believed that the advantages of lithium polymer batteries mentioned above are not difficult to understand. Mobile power supplies made from lithium polymer batteries can be carried more easily, safely, and without explosion. Lithium battery manufacturers want to better meet customer needs, there is no doubt that they will choose lithium polymer batteries.
