[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology in the late 20th century, the number of miniaturized devices has increased, which has put forward high requirements on power sources. Lithium batteries have entered the large-scale practical stage.
