ternary lithium battery PCB is a chemical battery using lithium as negative active material. The standard electrode potential of lithium is the most negative, the specific gravity is the lightest among metals, and the reactivity is the highest. Therefore, the electromotive force and specific energy of lithium batteries are very high, and they are an important high-energy battery. The positive active materials of lithium batteries include inorganic electrode materials such as oxides, sulfides, halides, halogens, and oxo acid salts, such as manganese dioxide, sulfur dioxide, copper sulfide, silver chromate, polycarbon fluoride, thionyl chloride, Iodine, etc.; electronically conductive polymers can also be used as positive electrode materials, such as polyacetylene, polypyrrole, polythiophene, polycarbazole, etc., also known as polymer batteries. The electrolytes of lithium batteries are non-aqueous solutions, solids and molten salts. The non-aqueous electrolyte is composed of organic solvent or non-aqueous inorganic solvent and inorganic salt. The organic solvents used are mainly propylene carbonate, dimethyl propionamide, acetonitrile, γ-butyrolactone, etc.; Liquid sulfur dioxide, etc. Inorganic salts include lithium perchlorate, lithium aluminum chloride, lithium fluoroborate, and lithium bromide. Because lithium and water react violently immediately upon contact, not only an aqueous solution cannot be used for the electrolyte, but all materials and components must be strictly dehydrated and reliably sealed. As an energy storage device integrating high energy density and high voltage, lithium-ion batteries have been widely used in mobile and wireless electronic devices, power tools, hybrid and electric vehicles and other fields.
