摘要:
Provided is a secondary battery electrolyte having improved high temperature properties and overcharge-prevention properties, particularly improved overcharge-prevention properties under high voltage/high current conditions, in conjunction with a minimized deterioration of the battery performance, by adding 3 to 5% by weight of cyclohexyl benzene (CHB) and 0.2 to 1.5% by weight of 2-fluoro biphenyl (2-FBP) as overcharge-preventing additives to an electrolyte of a lithium secondary battery.
