Title:
NON-AQUEOUS ELECTROLYTE, LITHIUM SECONDARY BATTERY PRECURSOR, LITHIUM SECONDARY BATTERY, AND MANUFACTURING METHOD FOR LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2022139324
Kind Code:
A
Abstract:
To provide a non-aqueous electrolyte that is resistant to discoloration even when stored for a long period of time in a high-temperature environment, and that can suppress an increase in DC resistance of a lithium secondary battery due to charging and discharging in a room-temperature environment.SOLUTION: A non-aqueous electrolyte contains at least one of lithium monofluorophosphate and lithium difluorophosphate, and a chain ether compound. The content of the chain ether compound is more than 0 mass ppm and 1000 mass ppm or less with respect to the total amount of the non-aqueous electrolyte.SELECTED DRAWING: None
