Abstract

The present application relates to an ionic compound, an electrolyte solution, a secondary battery and an electrical apparatus, wherein the ionic compound is represented by formula (1); wherein each R₁ is independently selected from alkyl having 1-10 carbon atoms substituted with fluorine or aryl having 6-30 carbon atoms substituted with fluorine, respectively; wherein any two adjacent —OR₁ groups and A⁻ can form a ring through the carbon atom in each R₁ as a site of attachment; A⁻ represents B⁻ or Si⁻, and Y⁺ represents a sodium ion or a potassium ion. The ionic compound can improve the cycling performance of secondary batteries such as sodium-ion batteries and potassium-ion batteries.
