Overview：Lithium manganese battery: the full name lithium manganese dioxide battery (Lithium-manganese dioxide, Li-MnO2). In a galvanic cell, lithium metal is used as the anode of manganese dioxide as the cathode. In a galvanic cell, the anode is the negative electrode, the electrons flow from the negative electrode to the positive electrode, and the current flows from the positive electrode to the negative electrode.

Lithium manganese dioxide battery has abundant kinds, such as lithium manganese dioxide battery for digital cameras, watches, cameras, digital cameras, thermometers, calculators, laptop BIOS, communications equipment, remote door locks. They have many shapes and sizes, with the common variety, the 3-volt "coin" type manganese variety, generally 20 mm in diameter and 1.6-4 mm thick. The heavy power demand of many of these devices is a particularly attractive option for lithium-ion batteries. Lithium batteries, in particular, can easily support short, heavy devices such as digital cameras that are currently in demand, and they maintain a higher voltage over an alkaline battery for a longer period of time.
Lithium-manganese dioxide batteries are made up of manganese dioxide which is treated by special process as positive electrode active material, lithium metal with high potential and high specific energy as negative electrode active material. The electrolyte adopts organic electrolyte solution with good conductivity. The battery structure has two forms: full-sealed and semi-sealed. Of course, the full sealing safety and retention period are better than half sealed.
Lithium manganese dioxide batteries are lithium metal and positive active material is manganese dioxide. The electrolyte is lithium perchlorate (LiClO4), an inorganic salt, dissolved in a mixed organic solvent of propylene carbonate (PC) and 1,2-dimethoxyethane (DME). Its chemical expression is as follows:
(-) Li/LiClO_4-PC+DME/MnO_2(+) battery negative electrode reaction: Li_Li+e positive electrode reaction: MnO_2+Li+e_MnO_2 (Li+) total reaction: Li+MnO_2_MnO_2 (Li+)

The reaction mechanism of lithium-manganese dioxide batteries is different from that of ordinary batteries. In non-aqueous organic solvents, lithium ions dissolved in anode lithium are transferred into the lattice of MnO2 by electrolyte to form MnO2 (Li+). Mn is reduced from +4 to +3, and its crystal structure does not change.
Lithium, due to its most negative potential, matches the cathode material with superior electrical properties. Lithium manganese dioxide battery is the lowest price and the best safety battery in lithium series primary battery. Open circuit voltage is about 3.3V, load voltage is 2.8V, nominal voltage is 3.0V, cut-off voltage is 2.0V, discharge voltage is relatively stable, suitable for high-power discharge.
