3.0 Volt - Primary / Non-Rechargeable Battery

Lithium Manganese Dioxide (Li-MnO₂) batteries are a type of primary (non-rechargeable) lithium battery, and come in shapes of cylindrical and coin. It is a light and highly-reliable battery with an operating voltage of 3V and can operate over a wide range of temperatures. This allows it to have a wide range of applications including: small devices, security equipment and other types of electronic devices.

 Main Features 

• High energy density: Li-MnO₂ batteries have a high energy density, which means they can store a large amount of energy in a small size.
• Wide operating temperature range: Li-MnO₂ batteries can operate in a wide temperature range, making them suitable for use in a variety of conditions.
• Stable voltage: Li-MnO₂ batteries have a stable voltage output throughout their discharge cycle, making them well-suited for use in applications that require a consistent power output.
• Lightweight: Li-MnO₂ batteries are lighter than other primary battery technologies, making them ideal for portable devices and small electronics.
• Good shelf life: Li-MnO₂ batteries have a good shelf life and can retain a significant amount of their stored energy for many years, even without use.
• High current discharge capability: Li-MnO₂ batteries have a high current discharge capability, making them suitable for use in high-power applications.

Principle and Reactions:

The positive active material of Li-MnO₂ batteries is Manganese Dioxide (MnO₂) and the negative active material is Lithium (Li).

Positive reaction:   MnO₂ + Li+ + e- → MnO₂Li

Negative reaction:   Li → Li+ + e-

Total reaction:   MnO₂ + Li → MnO₂Li

 Main Applications 

These features make Li-MnO₂ batteries popular for a variety of applications, including 

• Remote controls
• Medical devices 
• Military equipment
