CR (Cylindrical Type Lithium Manganese Dioxide Battery)

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.

• Designed lifetime at 20 deg. C when not yet used. Actual lifetime will vary depending on conditions such as discharge current and temperature.

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

Supports various package design configurations

Package design proposals are available according to the customer’s needs. We have designed a wide range of packages for 1 to 35 batteries.

35 parallel batteries for outdoor usage

Construction

Principle and Reactions

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

Safety precautions

If misused, this battery may deform, leak (the liquid inside the battery may leak to the outside), generate heat, explode, or ignite.
Since such misuse may cause injury or equipment failure, please be sure to read and observe [Warnings and Cautions].
