Liquid electrolyte
Liquid electrolyte is the most common type of electrolyte for lithium-ion batteries, which is mainly formed by lithium salts dissolved in organic solvents. Commonly used lithium salts include LiPF6, LiBF4, etc., while organic solvents are usually carbonates, such as dimethyl carbonate (DMC) and ethyl phenyl carbonate (EC).
peculiarity
High ionic conductivity: The liquid electrolyte has a high ionic conductivity, which can effectively ensure the charge and discharge performance of the battery.
Wide electrochemical window: The liquid electrolyte has a wide electrochemical window, which can support a large battery operating voltage and improve the energy density.
Good mobility: The liquid electrolyte can flow freely inside the battery cell, which helps the rapid conduction of ions.
shortcoming
Safety issues: Liquid electrolytes are mostly flammable organic solvents, and there is a risk of leakage and short circuit causing fire.
Temperature sensitivity: The performance of the liquid electrolyte may be affected at high or low temperatures, which poses a challenge to the operational stability of the battery.
Corrosion: Some liquid electrolytes may corrode the battery material, thus affecting the service life of the battery.
