In the past, mobile power sources used 18650 batteries. Because of their light weight and large capacity, 18650 batteries have won the favor of the majority of brands. However, with the maturity of polymer battery technology, manufacturers have begun to switch to polymer batteries. Why move? Should polymer batteries be used for the power supply?
1. What is a polymer battery? A polymer battery is a new type of high-density lithium battery. It uses colloidal polymer as the electrolyte. It can be made into batteries of various shapes and capacities according to product needs. The minimum thickness can reach 0.5mm. There is no charging memory effect. The picture below shows the polymer battery after dismantling the Greenlink mobile power supply.
2. What are the advantages of polymer batteries over 18650 batteries
1: The 18650 battery is an ordinary lithium battery, which uses a liquid electrolyte, while the polymer battery uses a gel electrolyte, so there will be no leakage;
2: The polymer battery has high density and strong plasticity. It can be made into any shape according to the requirements of the mobile power supply, and the mobile power supply of equal capacity is lighter and thinner;
3: When the 18650 battery is overcharged or short-circuited, it may cause the mobile power to explode, but the polymer battery will not.
3. Why polymer batteries are used for mobile power supplies? After talking about the advantages of polymer batteries, it is not difficult to understand that mobile power supplies made of polymer batteries can be lighter, thinner, portable, and safe and not exploding. If the manufacturer considers consumers, I would definitely choose polymer batteries.
