<P>PROBLEM TO BE SOLVED: To provide a high energy density non-aqueous rechargeable battery whose electrode expansion and contraction do not increase, whose electrically conductive network inside the electrodes is not broken, whose capacity does not decrease, and whoseinternal resistance does not increase, even when charge and discharge cycle is repeated. <P>SOLUTION: The non-aqueous electrolyte rechargeable battery has a positive electrode 1, a negative electrode 2 and non-aqueous electrolyte, wherein the negative electrode 2 is constructed using a three-dimensional structure collector on which a film is formed by depositing material containing element that can form alloy with lithium, and thin film formation method as eletroplating method, CVD method, PVD method, sputtering method, thermal spraying method, vacuum deposition method or the like is used for forming the film. <P>COPYRIGHT: (C)2004,JPO |
