摘要： PROBLEM TO BE SOLVED: To inhibit generation of SEI on the surface of a negative electrode active material and enhance a cycle characteristic by coating the surface of a negative electrode agent mainly containing a carbon with a coating film of LixSiyOz having a lithium ion-conductivity and specifying the ratio of silicon to lithium. SOLUTION: A coating film of LixSiyOz having a lithium ion-conductivity is applied on the surface of a negative electrode agent mainly containing a carbon for coating. A value of 100y/(x+y) being the ratio of silicon to lithium is preferably in the range of 10-80, more preferably in the range of 30-55 in order to enhance the maintaining rate of capacity after allowed to stand at a high temperature. When the value is in the range, the bond of LixSiyOz becomes one-dimensional, it is prevented that a film formed on the surface of the negative electrode agent becomes porous. Then, such deterioration that the lithium ion-conductivity is lowered, the resistance of the negative electrode becomes high and increased in IR drop is prevented. Regarding the coating amount on the surface of the negative electrode agent, LixSiyOz is desirably in the range of 0.01-10% to the negative electrode active material.

摘要： PROBLEM TO BE SOLVED: To provide a negative electrode for a lithium secondary battery of which charging capacity and cycle characteristic can be enhanced. SOLUTION: A negative electrode for a lithium ion secondary battery is composed of active material the surface of which is coated, and material of which potential gets higher than lithium potential for not less than 0.5 V, when a lithium ion is intercalated, and is higher than that of the negative active material which gets lower than the lithium potential for not more than 0.5 V, when the lithium ion is intercalated, is used for coating the surface. Thereby, a potential of the negative electrode can be prevented from being insufficiently lowered when rapidly charging.

摘要： PROBLEM TO BE SOLVED: To prevent the electrolyte density in an active material from being decreased to reduce a capacity, when the electrode temperature rises at the time of battery operation by connecting an active material and a current collector with a binder swollen due to a temperature rise, and impregnating it with a heated electrolyte. SOLUTION: An active material and a current collector are connected by a binder, such as PVDF, swollen by a temperature rise to obtain a lithium ion secondary battery electrode with the filling factor of 55-70%. The connected electrode is impregnated with an electrolyte heated to the temperature reached, when a battery is operated, e.g. about 60-120 deg.C. The binder is kept at the stable swollen state after the temperature is returned to the room temperature, the impregnation quantity of the electrolyte is increased, and the filling factor is set at 50-65%. As a result, the electrode which holds much electrolyte causes no lack of the electrolyte filling between active material grains, when the temperature rises and the binder is swollen during a battery operation and prevents reduction in the battery capacity caused by ion conductivity deterioration due to the electrolyte density reduction.
