1. Safety hazards of positive electrode materials When lithium-ion batteries are not used properly, the internal temperature of the battery increases, causing the analysis of active substances and oxidation of the electrolyte in the positive electrode material. At the same t...

Precautions for series and parallel connection of lithium iron phosphate battery packs: 1. Do not mix different brands of lithium iron phosphate battery packs, different capacities, or old and new lithium-ion batteries, and choose batteries with consistent performance. When...

The meaning of series and parallel connection of lithium iron phosphate battery packs: The series connection method refers to the connection of the negative electrode of the first lithium battery to the positive electrode of the second lithium battery, the negative electrode...

Introduction to BMS lithium-ion battery protection functions: 1. Battery protection, similar to PCM, includes over charging, over discharging, over temperature, over current, and short circuit protection. 2. Energy balance: The entire lithium-ion battery p...

Working principle of BMS lithium-ion battery protection board: The reason why lithium-ion batteries need protection is determined by their own characteristics. Due to the material of the lithium-ion battery itself, it cannot be overcharged, discharged, overcurrent, short cir...

Preservation of lithium-ion batteriesIt is said that someone has conducted experiments specifically, and after one year of standing, the total capacity of a fully charged lithium-ion battery will decrease by 20%; However, the total capacity of lithium-ion batteries charged to 40% only decreases by 5...

（1） High voltage charging: This charging method does not have a dedicated control circuit, and the battery with a protective board is charged directly with a 5V power head (or by stringing a diode to reduce voltage), completely relying on the high voltage limit of the protective board. The c...

After 100 cycles of charging and discharging, the electrolyte of cadmium nickel powered lithium-ion battery equipment should be replaced. Power lithium-ion battery equipment that is not frequently used also needs to replace the electrolyte once a year. If the capacity of power lithium-ion batt...

3. Discharge platform: The same positive electrode material, negative electrode material, and electrolyte are used, so theoretically the discharge platform is consistent. However, the internal resistance of the square battery is slightly higher, so the discharge platform is slightly higher....

Soft pack lithium-ion battery The key materials used in soft pack lithium-ion batteries include positive electrode materials, negative electrode materials, and separators, which are not significantly different from traditional steel and aluminum shell lithium-ion batteries. The bigg...
