[0025] Lithium batteries are generally batteries that use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use non-aqueous electrolyte solutions. There are three main types of lithium battery packaging, namely cylindrical, square and soft pack. Square lithium batteries usually refer to square batteries with aluminum shells or steel shells, and the popularity of square batteries is very high in China.
