The present invention relates to a lithium ion battery, more particularly to a new electrolyte and a lithium ion battery which comprises the same using an anode including graphitized carbon and a cathode including lithium-containing transition metal oxide. The present invention provides a compound of 4-carbomethoxymethyl-1,3-dioxan-2-one or 4-carboethoxymethyl-1,3-dioxolan-2-one represented by formula (1) which comprises both a cyclic ring carbonate structure and a linear carbonate structure, a lithium-containing electrolyte which includes the compound of formula (1), and a lithium ion battery which includes the electrolyte using the anode including graphitized carbon and the cathode including lithium-containing transition metal oxide. The lithium ion battery of the present invention fabricated by using the new compound has high electric capacity because of the graphitized carbon, and superior charge-discharge cyclic life characteristic and low temperature performance.
