Let the manufacturer tell you the little knowledge about lithium battery electrolytes

At present, lithium batteries can be divided into two types: inorganic solid electrolyte batteries and polymer solid lithium batteries. Let the lithium battery protection board manufacturer tell you some little knowledge about electrolytes today.

Firstly, the performance of the electrolyte has a crucial impact on the overall performance of the battery. Electrolytes have a crucial impact on the cycling performance, operating temperature range, and durability of lithium batteries. For lithium-ion batteries, the composition of electrolytes involves at least two aspects: solvents and lithium salts.

Electrolyte is one of the core materials for lithium battery capacity, which improves fluidity and acts as a medium. Electrolyte, as an important component of lithium-ion batteries, plays a role in transporting ions and conducting current between the positive and negative electrodes. Therefore, choosing the appropriate electrolyte is also the key to achieving high energy density, power density, long cycle life, and good safety performance of lithium-ion batteries.

The electrolyte of lithium batteries is the interaction between the electrolyte and electrode materials in the battery, which involves decomposition reactions and almost participates in all the reaction processes that occur inside the battery. At present, the electrolyte contained in lithium-ion batteries is mostly an organic system. Under the abuse of overcharge, overdischarge, short circuit, and thermal shock, the battery temperature rapidly increases, and the electrolyte generally has the problem of flammability, which often leads to battery fire and even explosion.

Electrolyte is an important component of lithium-ion batteries, playing a role in transporting ions and conducting current between the positive and negative poles. From the perspective of phase, lithium-ion battery electrolytes can be divided into three categories: liquid, solid, and molten salt electrolytes.
