| titleOfInvention | A kind of electrolyte solution for lithium ion battery |
| abstract | The invention discloses an electrolyte solution for a lithium ion battery, comprising an organic solvent, a lithium salt and an additive, the additive being an additive (I), or a combination of an additive (I) and an additive (II) or an additive (III) In combination, the additive (I) is selected from tetramethyltetravinylcyclotetrasiloxane, the additive (II) is vinylene carbonate, and the additive (III) is halogenated ethylene carbonate. The electrolyte contains tetramethyltetravinylcyclotetrasiloxane, which can form a stable high-temperature-resistant passivation film on the surface of the positive electrode when the battery is formed, and can effectively inhibit the dissolution of positive metal ions. The additives have a synergistic effect to form a superior SEI film, thereby slowing down the capacity decay of the battery during charge and discharge, and ensuring that the battery has excellent cycle performance. |
