The structure of the lithium battery is mainly divided into two types
The structure of the lithium battery is mainly divided into two types: a wound type and a stacked type. The liquid lithium battery uses a winding structure, and the polymer lithium battery has both. The coiled positive electrode film, the separator and the negative electrode film are sequentially placed and wound into a cylindrical shape or a flat cylindrical shape, and are mainly represented by SANYO, TOSHIBA, SONY, and ATL. The stacked type is stacked in a plurality of layers such as a positive electrode, a separator, a negative electrode, a separator, and a positive electrode. All the positive electrodes are welded together and the negative electrodes are also welded together, mainly represented by ATL.
