　　Lithium power batteries typically come in two types of shapes: cylindrical and rectangular. The interior of the battery adopts a spiral wound structure, which is separated by a very fine and highly permeable polyethylene film isolation material between the positive and negative electrodes. The positive electrode includes a lithium collector composed of lithium and cobalt dioxide, and a current collector composed of aluminum film. The negative electrode is composed of a lithium collector made of flake carbon material and a current collector made of copper thin film. The battery is filled with an organic electrolyte solution. In addition, safety valves and PTC components are installed to protect the battery from damage in abnormal states and output short circuits.

　　The voltage of a single lithium battery is 3.6V, and its capacity cannot be infinitely large. Therefore, single lithium batteries are often processed in series or parallel to meet the requirements of different occasions.
