LITHIUM SECONDARY BATTERY CONTAINING A NON-AQUEOUS ELECTROLYTIC SOLUTION

WIPO Patent Application WO/2010/056020

A2

The present invention relates to a lithium secondary battery comprising a negative pole for absorbing and discharging lithium ions, a positive pole made of a lithium-containing oxide, and a non-aqueous electrolytic solution. Said lithium-containing oxide contains a lithium nickel-based oxide, and said non-aqueous electrolytic solution contains both vinyl ethylene carbonate (VEC) and mono-nitrile. The lithium secondary battery of the present invention not only prevents the degradation of lifespan of charge/discharge cycles due to the use of lithium nickel-based oxide as a positive pole, but also suppresses the decomposition reaction of electrolytic solution even when the battery in a fully-charged state is kept at a high temperature or charged/discharged, thus preventing swelling and improving the lifespan characteristic of the battery even at a high temperature.
