The VARTA Microbattery lithium manganese dioxide cell chemistry was one of the first solid cathode cells commercially developed and is still the most widely used system today. These cells offer an excellent shelf life, good high-rate and low-rate capability, a wide operating temperature range and availability in button and cylindrical cell designs.
Delivered capacity is dependent on the applied load, operating temperature and cut-off voltage. Please refer to the charts and discharge data shown for examples of the energy/service life that the battery will provide for various load conditions. Delivered capacity is dependent on the applied load, operating temperature and cut-off voltage.
In the absence of a DC supply voltage, the lithium battery supplies the load with the necessary power. safety device must be incorporated. All VARTA Microbattery Lithium Cells and Batteries listed in Tab.10 are recognized by Underwriters Laboratories Inc. under UL-file number MH 13654 (N). The cells are marked with the Recognized Component Mark.
The amount of accumulated reverse current (IR) should be kept around 1% of the cell’s typical capacity during its standby life time. A maximum of 5μA continuously must not be exceeded. In the absence of a DC supply voltage, the lithium battery supplies the load with the necessary power. safety device must be incorporated.
2, as the cathode material. They function through the same intercalation /de-intercalation mechanism as other commercialized secondary battery technologies, such as LiCoO 2. Cathodes based on manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability.
The Mn (II) formed is soluble in most electrolytes and its dissolution degrades the cathode. With this in mind many manganese cathodes are substituted or doped to keep the average manganese oxidation state above +3.5 during battery use or they will suffer from lower overall capacities as a function of cycle life and temperature. 2.
