Abstract
Graphite material capable of absorbing and desorbing lithium is employed as the negative electrode material of a non-aqueous electrolyte secondary battery, the negative electrode material being bound by at least one type of material selected from the group consisting of polyethylene, ethylene-vinyl acetate copolymer, ethylene-propylene copolymer, ethylene-propylene-vinyl acetate copolymer, and polypropylene. A non-aqueous electrolyte secondary battery with a high anti-peeling strength of the electrode mix, superiority in the ease of handling, a high reliability in mass production, a superior low-temperature discharge characteristic and cycle characteristic is provided by employing the negative electrode in combination with a rechargeable positive electrode and a non-aqueous liquid electrolyte.
