Document Type and Number:
WIPO Patent Application WO/2024/037146
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of batteries, and specifically relates to an electrolyte solution and a battery comprising the electrolyte solution. The electrolyte solution comprises one or more fluorophosphite derivatives, which have a structure as shown in formula (I), where R1 and R2 are each independently selected from halogen-substituted or unsubstituted C1-C20 alkyl, C3-C20 cycloalkyl, phenyl, biphenyl, C6-C26 phenylalkyl and C6-C26 condensed polycyclic aryl, and a dangling bond; and R3, R4, R5 and R6 are each independently selected from H and halogen. The electrolyte solution of the present disclosure has relatively high oxidation resistance and flame retardance, and low impedance at a low temperature. The battery of the present disclosure has lower impedance, higher cycle performance and higher safety performance.
