A lithium secondary battery for use in electric vehicle, includes: a battery case, and an electricity-generating body including a positive electrode, a negative electrode, and a separator, the positive and the negative electrode being wound or laminated via the separator so that the positive electrode and negative electrode are not brought into direct contact with each other. Each single battery has a product (RxE) of battery internal resistance R (m OMEGA ) and battery energy E (Wh), of 50 to 900 (m OMEGA .Wh). The lithium secondary battery is used in an electric vehicle as combined batteries formed by connecting a required number of the single batteries in series, wherein the negative electrode is a copper foil coated with a negative electrode active material consisting of a highly graphitized carbon material. <IMAGE> |
