The electrolyte is mainly composed of organic solvents, conductive salts and additives. It is used to provide a medium for ion migration and ensure the reversibility of electrochemical reactions inside the battery. In lithium batteries, the electrolyte plays a key role in conducting electrons and is the guarantee for lithium-ion batteries to obtain advantages such as high voltage and high specific energy. At the same time, the electrolyte is also corrosive and flammable to a certain extent, and appropriate protective measures need to be taken during operation.
