| titleOfInvention | A kind of electrolyte and a kind of lithium ion battery |
| abstract | The present invention provides a kind of electrolyte, including lithium salts, nonaqueous solvents and additive, the chemical formulas of the additive are as follows: Li x PO y F z , wherein 0≤x≤3；0≤y≤4；0≤z≤4, x, y, z are integer, cannot simultaneously be zero, and to meet chemical formula requirement.The Li of high concentration is added in the present invention in the electrolytic solution x PO y F z For additive, and form milky white shape suspension electrolyte.Since the additive can be deposited on electrode surface during circulating battery, it can be effectively improved the structure of the surface passivated membrane of electrode material, to improve the charge/discharge capacity and cycle life of lithium ion battery.Further study show that the additive is in cyclic process and is not involved in electrochemistry and chemical reaction, but lithium ion is complexed and is deposited in negative terminal surface, complexing lithium salts anion is deposited in positive electrode surface, hinders the further decomposition of electrolyte. |
