Abstract
The present disclosure provides an electrolyte additive, an electrolyte and a lithium ion secondary battery containing the same. The electrolyte additive has a structure of Formula (1), wherein R1 is hydrogen, a phenyl, a cyano group, an alkyl cyano group or a C1 to C6 alkyls, and each of R2 to R5 is independently selected from hydrogen or a C1 to C6 alkyl. By means of the electrolyte additive, the electrolyte and the lithium ion secondary battery containing the same of the present disclosure, a technical effect of improving electric performance of the lithium ion secondary battery at high voltage and high temperature is achieved.
