【SMM popular science: Application of electrolyte additive agents in the lithium battery industry】Electrolyte additive agents refer to the small amount of additives added to the electrolyte to improve its electrochemical properties and enhance the quality of cathode deposition. By adding a small amount of additives to the electrolyte of lithium-ion batteries, it is possible to selectively improve certain performance aspects of the battery, such as reversible capacity, electrode/electrolyte compatibility, cycle performance, rate performance, and safety performance, playing a crucial role in lithium-ion batteries. The amount of electrolyte additive agents is generally small, but they are an indispensable part of the electrolyte system.
