Maxell Cylindrical CR Type Lithium Manganese Dioxide Battery

The cylindrical type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material.

Maxell’s cylindrical type lithium manganese dioxide battery realizes stable discharge characteristics with its original sealing structure, improved electrical-conductivity structure, and negative electrode material. This battery’s long-term reliability makes it ideal for use as a power source in industrial applications such as IoT devices and smart meters (e.g. gas, water, electricity). Battery packs can also be produced to meet special customer requirements. For details, please contact your nearest Maxell dealer or distributor.

The cylindrical type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material.

Battery Reactions
Positive reaction : MnO2+Li++e- → MnOOLi
Negative reaction : Li → Li++e-
Total reaction : MnO2+Li → MnOOLi

Features

  • High energy density
    High energy density has been achieved by optimizing the filling rate of the material by means of a unique electrode structure.
  • Long-term reliability lasting more than 10 years*
    The employment of a heat-resistant gasket and a laser-seal structure prevents water intrusion and electrolyte evaporation, ensuring long-term reliability that lasts more than 10 years*. The self-discharge rate is about 0.5% per year.
  • Stable discharge characteristics
    The original negative electrode material maintains low internal resistance even at high depths of discharge and ensures stable discharge.
  • Superior low-temperature characteristics
  • High safety due to internal short-circuit prevention structure

Applications

  • Smart meters (e.g. gas, water, electricity)
  • IoT devices
  • Communication devices (e.g. 3G, LTE, LPWA)
  • In-vehicle devices
  • Security devices
  • Memory backup power
