In the past, all mobile power supplies used 18650 batteries. Because of its light weight and large capacity, 18650 batteries have won the favor of many brands. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power supplies begin to use 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. With collagen fiber polymer as electrolyte, it can be made into batteries of various shapes and capacities according to equipment requirements. The minimum wall thickness can reach 0.5mm, and it has no battery charging memory.
二、 What are the advantages of lithium polymer batteries over 18650 batteries?
1. 18650 battery is a common lithium battery, which uses liquid electrolyte, and lithium polymer battery uses gel electrolyte, which is not easy to leak.
2. Lithium polymer battery has high relative density and strong ductility. It can be made into the shape required by customers according to the requirements of mobile power. Mobile power with equal capacity is lighter.
3. When the 18650 battery is overcharged or short circuited, it is likely to cause an explosion of the mobile power supply, while the lithium polymer battery is not easy.
三、 Why do mobile power supplies use lithium polymer batteries?
It is believed that after the advantages of lithium polymer batteries mentioned above, it is not difficult to understand that mobile power supplies made of lithium polymer batteries can be carried more easily and safely without explosion. Lithium battery manufacturers want to better meet the needs of customers, there is no doubt that they will choose lithium polymer batteries.
