Background
In the first charge and discharge process of the liquid lithium ion battery, the electrode material and the electrolyte react on a solid-liquid phase interface to form a passivation layer covering the surface of the electrode material. The passivation layer is an interfacial layer, characterized by a solid electrolyte, which is an electronic insulator but Li + Of good electrical conductivity, Li + Can be freely inserted and extracted through the passivation layer, so the passivation film is called a solid electrolyte interface film (SEI film) for short. The formation of the SEI film has a crucial influence on the performance of the electrode material. On one hand, the formation of the SEI film consumes part of lithium ions, so that the irreversible capacity of the first charge and discharge is increased, and the charge and discharge efficiency of the electrode material is reduced; on the other hand, the SEI film has organic solvent insolubility and can stably exist in an organic electrolyte solution, and solvent molecules cannot pass through the passivation film, so that co-embedding of the solvent molecules can be effectively prevented, damage to an electrode material due to the co-embedding of the solvent molecules is avoided, and the cycle performance and the service life of the electrode are greatly improved. Therefore, intensive research on the formation mechanism, composition structure, stability and influence factors thereof of the SEI film and further search for effective ways to improve the performance of the SEI film are always hot spots of research in the world electrochemical world.
The vinyl ethylene sulfite is a sulfite compound, has a vinyl functional group, has low lowest unoccupied orbital (LUMO) energy level, has strong electron obtaining capability, is easy to reduce, generates electrochemical reaction firstly to form an SEI protective film, and is an excellent SEI film forming additive.
