| titleOfInvention | Electrolyte for silicon carbon system lithium ion battery and silicon carbon system lithium ion battery |
| abstract | The invention provides an electrolyte for a silicon carbon system lithium ion battery and a silicon carbon system lithium ion battery. The electrolyte includes a non-aqueous organic solvent, an additive and a conductive lithium salt, and the additive is selected from grafted polysilane compounds; the silicon-carbon system lithium ion battery includes the above-mentioned electrolyte. The grafted polysilane compound can generate a thin layer of polysulfate on the surface of the positive and negative electrodes during the charging and discharging process of the battery, especially the ring-opening of the sulfur-containing cyclic ester group, and has a high conductivity to Li + ; at the same time; , the Si-H bond is oxidized and cross-linked to form a rigid Si-O-Si cross-linked structure to enhance the thermal stability of the positive electrode surface film, and the effect of suppressing gas production at high temperature of the positive electrode material is significantly improved; A strong SEI film is formed on the surface, which effectively reduces the damage and reorganization of the SEI film caused by the expansion of the silicon anode during the cycle. |
