5. Safety hazards during battery useDuring the use of lithium-ion batteries, overcharging or discharging should be minimized as much as possible, especially for batteries with high monomer capacity. Thermal disturbances may cause a series of exothermic side reactions, leading to safety issues....

3. Safety hazards of membranes and electrolytes The electrolyte of lithium-ion batteries is a mixed solution of lithium salts and organic solvents, among which the commercially available lithium salt is lithium hexafluorophosphate. This material is prone to thermal analysis...

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...
