There are two types of lithium batteries: cylindrical and square. The internal battery is used in a spiral winding structure, which is made of a very fine and very penetrating polyethylene film isolation material. The positive electrode includes a current collection pole consisting of lithium cobaltate (or lithium nickel cobalt, lithium manganate, lithium phosphate, etc.) and aluminum foil. The negative electrode consists of a current collection of carbonized carbon -based materials and copper foil. The battery has an organic electrolyte solution. In addition, the safety valve and PTC component (partial cylindrical) can be installed so that the battery is not damaged when the battery is protected when the battery is abnormal and output short circuit.
The voltage of a single -section lithium battery is 3.7V (the positive iron phosphate is 3.2V), and the battery capacity cannot be infinitely large. Therefore, the single -section lithium battery is often skewed and parallel to meet the requirements of different occasions.
