3.8v Flexible Lithium Polymer Battery


Product Description

3.8v 220mah Flexible Lithium Polymer Battery 1420138 lithium ion battery
 
Features of flexible batteries:
Traditional lithium batteries are rigid. When they are bent or folded, it is easy to cause the electrode material and current collector to separate, affect the electrochemical performance, and even cause short circuits. Serious safety problems occur.
 
But flexible battery means that it can withstand bending and twisting and stretching even foldable batteries.It can maintain stable electrochemical performance in a bent state and serves as an important energy storage device for wearable electronic devices.

Serial numberprojectstandardTest Methods
1Open circuit voltage3.9 V ±0.50VThe voltmeter measures that the battery is 40%-50% charged .
2AC internal resistance≤ 1 40 mΩMeasured with an AC internal resistance tester with a frequency of 1KHz under 40%-50% charge .
30.1C discharge≥ 225 mAhAt an ambient temperature of 25°C ± 5°C, let the standard stand for 10 minutes after charging, and then discharge to the end voltage at 0.1C. Cycle 3 times. When one discharge reaches the standard, it can be terminated .
40.5C discharge≥ 2 20mAhUnder the ambient temperature of 25℃±5℃, let the standard stand for 10min after charging, and discharge to the termination voltage at 0.5C, cycle 3 times. When one discharge reaches the standard, it can be terminated.
5Cycle life≥ 500 timesUnder the ambient temperature of 25℃±5℃, discharge with 0.5C current constant current to the end voltage, then charge with 0.5C current constant current and constant voltage to the cut-off current, let it stand for 10min, and then perform the next charge and discharge cycle until 0.5C The constant current discharge capacity is less than 176 mAh.
6High temperature discharge≥ 2 20 mAhAfter standard charging, the battery is placed in a high-temperature box at 45°C±2°C for 2h, and then discharged at 0.5C to the end voltage.
7Low temperature discharge≥ 198 mAhAfter standard charging, the cell was placed in -10 ℃ ± 2 ℃ a cold box thermostat 4h, then of 0. The 2 discharged to a final voltage C.
8Charge retention

The remaining capacity

≥ 205 mAh

 

Recovery capacity

≥ 110 mAh

After standard charging , the battery is left open for 28 days at an ambient temperature of 25°C±5°C, and then discharged at 0.5°C to an end-of-discharge voltage at an ambient temperature of 25°C±5°C. Then perform standard charging, and then discharge at 0.5C to the end-of-discharge voltage at an ambient temperature of 25℃±5℃ (can be cycled for 3 weeks).
9Storage≥ 205 mAhAt an ambient temperature of 25°C±5°C, the battery is charged with a capacity of 40% to 45% using 0.5C, and then stored at 25°C±5°C and a relative humidity of 45% to 85% for 12 months. Charge the battery as standard, and then discharge it at 0.2C to an end voltage at an ambient temperature of 25°C ± 5°C (the above charge and discharge test can be cycled 5 times).
