Title:
ELECTROLYTE, ELECTROCHEMICAL DEVICE, LITHIUM ION SECONDARY BATTERY, AND MODULE
Document Type and Number:
WIPO Patent Application WO/2019/150895
Kind Code:
A1
Abstract:
Provided is an electrolyte capable of improving the high-temperature storage characteristics and cycle characteristics of an electrochemical device. The electrolyte includes at least one type of compound indicated by general formula (1–1) (in the formula, R101 indicates a C1–7 alkyl group, etc., which may be fluorinated and may include O etc., in the structure thereof.) and general formula (1-2) (in the formula, R102 and R103 (i) each independently indicate H, F, or a C1-7 alkyl group, etc., which may be fluorinated or (ii) are joined together and are a hydrocarbon group that forms a 5-member or 6-member heterocycle together with a hydrogen atom, and may include O etc., in the structure thereof.)
