Abstract
A lithium secondary battery including a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a sulfur dioxide-based inorganic electrolyte solution. The negative electrode includes a negative electrode active material which includes a carbon material having a coating comprising titanium oxide (TiO, 0<x<2). The titanium oxide improves the wettability of the carbon material negative electrode to the inorganic electrolyte solution and the charge transfer reaction on the surface and minimizes the interfacial resistance of the carbon material/inorganic electrolyte solution, thereby improving the high-rate charge/discharge characteristics.
