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 non-aqueous electrolyte secondary battery having both high capacity and long-life is provided by solving the problem of the large irreversible capacity of a negative electrode active material. The non-aqueous electrolyte secondary battery is produced by a method including the steps of: reacting lithium with a negative electrode active material by bringing a metal film that is composed mainly of lithium into contact with a surface of a negative electrode active material layer; and thereafter combining the negative electrode with a positive electrode to form an electrode assembly. The metal film composed mainly of lithium is preferably formed on a carrier that does not chemically react with lithium, and the metal film on the carrier is preferably brought into contact with the negative electrode active material layer while heating and applying a pressure thereto.
