3.7v battery cell Manufacturers

Lithium iron phosphate batteries have a variety of unique advantages such as high working voltage, high energy density, long circulation life, and environmental protection. They support unspeed extensions. After configured the energy storage system, large -scale power storage can be performed. Lithium iron phosphate battery energy storage system consists of lithium iron phosphate battery pack, battery management system (BMS), converter device (rectifier, inverter), monitoring system, transformer, etc.

In recent years, lithium batteries have been used more and more widely in our lives. According to different application fields, lithium batteries can be roughly divided into three types: consumer type, power type and energy storage type.

Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.

Is there any special reason for the use of aluminum foil and copper foil for the current collection of positive and negative electrodes? Is there any problem with using it in reverse?
