Title:
NONAQUEOUS ELECTROLYTE AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/054667
Kind Code:
A3
Abstract:
The present invention relates to a nonaqueous electrolyte and a lithium secondary battery comprising same and particularly to a nonaqueous electrolyte comprising an HF detecting agent, and a pouch-type lithium secondary battery comprising same, thereby allowing the presence/absence of hydrofluoric acid to be identified with the naked eye without the disassembly of the cell and enabling easy detection of a defect during the manufacture of the secondary battery.
