Abstract
The present disclosure provides a lithium ion secondary battery and electrolyte solution thereof. The electrolyte solution of the lithium ion secondary battery includes a nonaqueous organic solvent, and a lithium salt dissolved in the nonaqueous organic solvent. The nonaqueous organic solvent includes a dicyano ester compound of a structure shown by Formula I, Formula II, or Formula III. Formula I represents dicyano carbonate ester compounds, Formula II represents dicyano sulfite ester compounds, Formula III represents dicyano sulfate ester compounds, and the value n is an integer between 1 and 4. The lithium ion secondary battery according to the present disclosure includes the aforementioned electrolyte solution. At a working voltage of 4.3 V or higher, the lithium ion secondary battery according to the present disclosure can effectively suppress the oxidation of the electrolyte solution and improve the storage performance of the lithium ion secondary battery at high temperature.
