LITHIUM SECONDARY BATTERY CONTAINING ADDITIVES FOR IMPROVED HIGH-TEMPERATURE CHARACTERISTICS |
摘要 |
Provided is a secondary battery containing polyalkyleneglycol diglycidylether represented by formula I added in a predetermined amount to an electrolyte for the battery. The secondary battery containing the above additive exhibits remarkably improved high-temperature characteristics, prevents deterioration in rate characteristics and cycle characteristics, and considerably reduces thickness swelling of the battery so as to prevent battery leakage, ultimately enhancing safety of the battery. |
