18650 battery pack 12v.Battery detection results:

release time:2023-10-14 Hits: Popular:AG11 battery

　　Battery detection results:

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

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

　　3. At a high temperature of 125°C, the battery is discharged at a constant current of 16mA/g and the cut-off voltage is 2.0V. The battery can be discharged normally, the discharge curve is stable, and the specific capacity of the cathode material is 260mAh/g. Obviously, the material has better high-current discharge capability at high temperatures.

　　Low temperature and high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%

　　Charging temperature: 0~45℃ Discharge temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ Discharge capacity retention rate: 0.5C Discharge capacity ≥ 60%

　　4. Leave the battery at 125°C for 120 hours, and then discharge it at a constant current of 16mA/g. The discharge cut-off voltage is 2.0V. The specific capacity of the cathode material is 250mAh/g. It is stated that the high-temperature cathode material remains relatively stable at 125°C. Minimal analysis or deterioration occurs.

　　5. The battery was discharged at a constant current of 16mA/g at 150°C and tested for 8 hours, exceeding the requirement of 7 hours of operation at 150°C for the TPMS system. The working voltage platform of the battery is normal and no abnormal platform appears, which means that no new phase of the cathode material has sprouted, the properties are stable, and the battery can continue to discharge.
