Lithium-manganese batteries, also known as lithium-manganese dioxide batteries, use specially treated manganese dioxide as the positive electrode active material and high potential and high specific energy lithium metal as the negative electrode active material, the electrolyte adopts organic electrolyte solution with good conductivity, and the battery structure has two forms of full seal and half seal. Because the discharge curve of lithium-manganese battery is stable, many high-tech products such as motherboard use it as a backup battery for memory.
1. The specific energy of lithium-manganese Battery is 270WH/kg, 2. The open-circuit voltage is high, and the working voltage varies with load from 2.7 to 3.0 V. 3. The self-discharge rate is low, the annual self-discharge rate is less than 2% , the storage life is long, it can be stored for 10 years at room temperature. 4. The winding structure can discharge at high current. Use a wide range of temperatures (-20 °C to + 60 °C) . 6, completely sealed, good reliability, no leakage. 7. Lithium-manganese battery has lower cost and better reliability than lithium-cobalt battery, but its cycle life is not good at high temperature.
