How to Ensure the Safety of Lipo Batteries:

Electrolyte Improvement:

The main heat release during lithium-ion battery fires comes from the combustion of flammable organic electrolytes. Research is ongoing to develop electrolytes with better thermal stability and lower flammability.
Soft solvent lithium-ion batteries, for instance, have been designed to enhance safety and performance under extreme conditions.

Cell Structure:

Voltage and Current Matching:

Ensure that the battery's voltage and current capacity match the requirements of the device it powers.
Over-voltage or over-current can lead to battery damage or safety hazards.

Charging and Discharging Practices:

Use dedicated LiPo battery chargers that provide the correct voltage and current.
Avoid overcharging or deep discharging, as both can shorten battery life and increase safety risks.
Monitor battery temperature during charging and discharging to prevent overheating.
