Paragraph 0010; 0035, (2020/12/31)
The invention relates to a phosphate compound, a method for synthesizing the phosphate compound, and a non-aqueous electrolyte; the main means for suppressing side reactions on the surface of an electrode comprises coating an electrode active material and adding an effective film-forming additive to an electrolyte to form a passivation film having sufficient thickness and density on the surface ofthe electrode; the two means are undoubtedly used for preventing the electrolyte from contacting the surface of the electrode to obtain and lose electrons and preventing the surface of the electrodefrom being corroded by decomposition byproducts of the electrolyte. The phosphate compound disclosed by the invention has the beneficial effects that the phosphate compound is easy to prepare and purify, high in thermal stability, convenient to store, strong in compatibility with other components of an electrolyte and other components in a battery, moderate in viscosity, high in dielectric constant, capable of dissolving a lithium salt, has certain wetting capacity, and has flame-retardant and positive and negative electrode surface film-forming functions.
