Research on high-temperature 14250 battery manganese dioxide battery positive electrode materials

 

High-temperature 14250 battery manganese dioxide battery is an important primary power source, widely used in automobile tire pressure monitoring system (TPMS) and medical instruments. Although my country is a major manufacturer of primary batteries, it is blank in the field of high-end high-temperature primary 14250 battery batteries. The lack of positive electrode materials suitable for high-temperature applications is one of the reasons that restrict the development of high-temperature 14250 battery manganese dioxide batteries. Above 100°C, the reaction between manganese dioxide and electrolyte becomes increasingly intense, causing the electrolyte to decompose and produce a large amount of gas, and an inert oxide layer is formed on the surface of manganese dioxide, causing ohmic polarization to increase. All these factors lead to the performance degradation of 14250 battery manganese dioxide batteries at high temperatures and they cannot work.

 

Our company has conducted in-depth research on manganese dioxide positive electrode materials suitable for high temperature use, starting from controlling the ratio of γ and β crystals of manganese dioxide, and doping elements to obtain high-temperature manganese dioxide (G-MnO2).

 

Material performance test method:

 

Mix high-temperature manganese dioxide: conductive agent: adhesive in a ratio of 92:4:4, use ethanol as solvent, and make positive electrode sheets by rolling film.

 

The obtained positive electrode sheets are assembled with 14250 battery sheets, polypropylene separators, and electrolytes to form CR2032 batteries for testing.

 

Battery test results:

 

1. At room temperature (20±5), discharge at a stage constant current (8-3-1.5-0.6-0.3mA/g), the cut-off voltage is 2.0V, and the specific capacity of the positive electrode material is 264mAh/g.

 

2. At low temperature (0±2), discharge at a stage constant current (16-8-3-1.5-0.6-0.3mA/g), the discharge curve fluctuates due to temperature changes, and the discharge specific capacity of the material is 261mAh/g.

 

3. At a high temperature of 125, the battery was discharged at a constant current of 16mA/g, with a cut-off voltage of 2.0V. The battery was able to discharge normally, the discharge curve was stable, and the specific capacity of the positive electrode material was 260mAh/g. Obviously, the material has better high current discharge capacity at high temperature.

 

4. The battery was left at 125for 120 hours, and then discharged at a constant current of 16mA/g, with a discharge cut-off voltage of 2.0V. The specific capacity of the positive electrode material was 250mAh/g, indicating that the high-temperature positive electrode material remained relatively stable at 125, and the degree of decomposition or deterioration was very small.

 

5. The battery was discharged at a constant current of 16mA/g at 150for 8 hours, which exceeded the requirement of the TPMS system to work at 150for 7 hours. The working voltage platform of the battery is normal, and no abnormal platform appears, indicating that no new phase is generated in the positive electrode material, the properties are stable, and the battery can continue to discharge.

 

The electrical performance and shelf durability of CR2032 batteries made of high-temperature manganese dioxide materials developed by our company were tested at room temperature, low temperature and high temperature (125, 150). The specific capacity of this material reached more than 260mAh/g, the discharge curve was stable, and the manganese dioxide material remained relatively stable at high temperature. This material is completely suitable for working at high temperatures and can be used as the positive electrode material of TPMS batteries.
