Sulfur phosphate compound, non-aqueous lithium ion battery electrolyte containing sulfur phosphate compound and lithium ion battery

The invention discloses a thiophosphate compound, a synthesis method and a non-aqueous electrolyte. After the compound is applied to a battery with the non-aqueous electrolyte, even if the battery isunder high voltage, an electrode/electrolyte interface of a lithium ion battery is effectively improved, so that an electrode surface film is stabilized, side reactions are reduced, the stability of the battery under high temperature and high voltage is improved, and the cycling stability of the battery is improved, and meanwhile, the self-extinguishing time of the non-aqueous electrolyte after combustion is shortened, the flame retardance is improved, and the safety performance of the battery is improved.
