Abstract: Systems and methods for a lithium-ion battery cell are disclosed. In one example, a method for forming a cathode for a lithium-ion battery cell includes forming a pre-lithiated cathode with a pre-lithiation reagent and positioning the pre-lithiated cathode in contact with an electrolyte. An electrolyte additive is injected into the electrolyte to form a passivation layer at the pre-lithiated cathode, the passivation layer inhibiting continued decomposition of the pre-lithiation reagent of the pre-lithiated cathode after completion of a formation cycle of the lithium-ion battery cell.

Abstract: The present disclosure provides an electrolyte and a secondary battery. The electrolyte comprises: a non-aqueous organic solvent; an electrolyte salt dissolved in the non-aqueous organic solvent; and an additive dissolved in the non-aqueous organic solvent. The additive comprises a first additive, the first additive is selected from boron phosphate represented by formula 1. When the electrolyte of the present disclosure is applied in the secondary battery, the performances of the secondary battery under high temperature environment can be effectively improved.
