The role of lithium ion battery electrolyte

The electrolyte is one of the core materials of a lithium secondary battery and a lithium primary battery capacity which constitutes an energy source for carrying a mobile phone, a notebook, a video recorder, etc., and which improves the fluidity between the moving anode and the cathode and acts as a medium. As an important part of lithium-ion battery, electrolyte plays the role of transporting ion conduction current between positive and negative electrodes. Choosing the right electrolyte is also the second time to obtain high energy density and power density, long cycle life and good safety. The key to the battery.

The electrolyte of a lithium battery is the interaction between the electrolyte and the electrode material in the battery, and itself has a decomposition reaction, which is involved in almost all reaction processes occurring inside the battery. At present, the electrolyte contained in the lithium ion battery is mostly an organic system. Under the conditions of overcharging, overdischarge, short circuit and thermal shock, the temperature of the battery rises rapidly, and the electrolyte generally has a problem of flammability, which often leads to The battery caught fire and even exploded.

Electrolyte is an important component of lithium-ion batteries, which transports ions and conducts current between the positive and negative poles. From the phase state, lithium-ion battery electrolytes can be divided into liquid, solid and molten salt electrolytes.
