The polymer battery core is also a component of the lithium ion battery. Generally, the components of the lithium ion battery are: the battery core and the protection circuit board, the circuit board has a control effect on the current and the voltage, and the protection function is performed, and the battery core is in the battery. The power storage part, the quality of the battery will directly affect the quality of the battery. Lithium polymer batteries are generally made of lithium cobalt oxide, lithium manganate and ternary lithium. Different from the traditional lithium ion battery manufacturing process, lithium polymer batteries are entangled, soft in volume and mushy. The outer packaging is made of aluminum plastic film, and the shape can be customized.

    Due to its flexible design, it is used by mobile phone manufacturers. Smartphones such as the iPhone that we are familiar with use polymer batteries. Compared with the traditional lithium battery, the capacity of the polymer battery is larger, about 30% higher, and the safety factor is higher, and the explosion risk is small.

At present, the market is relatively large, still using 18650 batteries of mobile power, many batteries, mobile power brands, most products use 18650 batteries. Doka recommends that users consider the use of polymer batteries when purchasing mobile power, especially for mobile power with large capacity, such as 8000mAh or more. If multiple 18650 batteries are connected in parallel, it is terrible once an explosion occurs. The polymer battery is absolutely not explosive, and at most it produces a flame.
