摘要： A charger for a secondary battery including a positive electrode, a negative electrode including lithium-containing silicon represented by the composition formula LixSi, and an electrolyte. This charger includes: (1) a voltage detector that detects voltage of the secondary battery that is being charged; and (2) a charge controller that calculates the value x in LixSi included in the secondary battery from an output of the voltage detector and stops the charging of the secondary battery when the calculated value x reaches a predetermined threshold value. The charge controller has at least one settable threshold value including a first threshold value, and the first threshold value is 2.33 or less. The use of this charger makes it possible to charge the secondary battery such that it has a high capacity, or a higher capacity if necessary, without accelerating the deterioration of cycle life.

摘要： A negative active material thin film containing silicon as a main component is formed on a collector. A composition gradient layer, in which a composition distribution of a main component element of the collector and silicon is varied smoothly, is formed in the vicinity of the interface between the collector and the negative active material thin film. The composition gradient layer contains at least one kind of third element selected from W, Mo, Cr, Co, Fe, Mn, Ni, and P, in addition to the elements contained in the collector and the elements contained in the negative active material thin film. The third element irregularizes the atomic arrangement at the interface between the collector and the negative active material thin film. Therefore, even when the negative active material absorbs/desorbs ions during charging/discharging, thereby allowing silicon particles in the negative active material to expand/contract, the strain at the interface involved in the expansion/contraction of the silicon particles is alleviated, and peeling at the interface between the negative active material thin film and the collector is suppressed. Consequently, cycle characteristics are enhanced.
