    Lithium electronic battery charging and discharging principle structure diagram


    Basic characteristics and principle of lithium battery

    A lithium battery is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li + MnO2 = LiMnO2 The reaction is a redox reaction, discharge.

    Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. Now lithium batteries have become mainstream.
