Sony CR2032 Lithium Coin Battery

Coin Manganese Dioxide Lithium Batteries are being used in a broad range of applications, from quarts watches and clocks, a backup power sources for memories requiring long-term reliability over 10 years to IoT equipment, and car keyless entry systems. Lithium metal, used for the anode in Coin Manganese Dioxide Lithium Batteries, has the largest electric capacity per unit weight (3.86 Ah/g) among all the materials usable for the anode. Thus, batteries with a high energy density can be produced. Also, by using different active materials for the cathode, batteries with diverse characteristics can be made. Sony has commercialized the Coin Manganese Dioxide Lithium Batteries, which uses manganese dioxide for the active cathode material for superior stability.
