ABSTRACT:
The present invention is an electrolyte for a lithium ion rechargeable battery and a lithium ion rechargeable battery that includes the same. More particularly, the present invention discloses an electrolyte for a lithium ion rechargeable battery that provides excellent cycle life characteristics and high-temperatures storage stability and prevents a drop in discharge capacity of a battery at low temperature, and a lithium ion rechargeable battery including the same. The lithium ion rechargeable battery including the electrolyte provides improved cycle life characteristics and prevents the problems of a drop in discharge capacity at low temperature and high-temperature swelling through the formation of a stable SEI film at the initial charge cycle.
