폴리머 리튬 배터리 또는 원통형 리튬 이온 배터리 중 어느 것이 더 낫습니까? Posted by batterymanufactory.com
1. Material Lithium ion batteries use liquid electrolytes, while polymer lithium batteries use gel electrolytes and solid electrolytes. In fact, a polymer battery cannot really be called a polymer lithium battery. It cannot be a real solid state. It is more accurate to call it a battery without flowable liquid. 2. Packaging method and appearance The polymer lithium battery is encapsulated with aluminum-plastic film, and the shape can be customized at will, thick or thin, large or small. Lithium-ion batteries are packaged in a steel case, and the most common shape is cylindrical, the most common is 18650, which refers to 18mm in diameter and 65mm in height. The shape is fixed. Can't change at will. 3. Security There is no flowing liquid inside the polymer battery, and it will not leak. When the internal temperature is high, the aluminum-plastic film shell is just flatulence or bulging and will not explode. The safety is higher than that of lithium-ion batteries. Of c...
