    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.

    摘要： A manufacturing method according to the present invention includes a step of allowing lithium to deposit on a substrate provided with a layer capable of forming a compound together with lithium. A first beta ray and a second beta ray are emitted toward the substrate for irradiation before the deposition step to measure backscattering, from the substrate, of the first beta ray and the second beta ray. The first beta ray and the second beta ray are emitted toward the substrate for irradiation after the deposition step to measure backscattering, from the substrate, of the first beta ray and the second beta ray. A decrement in backscattering of the first beta ray before and after lithium deposition and a decrement in backscattering of the second beta ray before and after lithium deposition are calculated. The deposition step is controlled depending on the decrement in the backscattering of the first beta ray and the decrement in the backscattering of the second beta ray.

    摘要： The present invention provides a vacuum deposition apparatus configured to simultaneously form a power collecting lead forming portion and an electrode active material portion of a lithium-ion secondary battery and having excellent mass productivity. With shutters 12a and 12b closed, a substrate 4 winding around a first roll 3 is unroll to be conveyed to a second roll 8, and the substrate 4 stops when it reaches first and second deposition possible regions 60a and 60b. Here, the shutter 12a opens, and a deposition material in a crucible of an evaporation source 9 is evaporated to be supplied to a surface of the substrate 4 which is located in the first deposition possible region 60a. With this, a first layer is formed as a deposited film on the surface of the substrate 4. After the deposition is carried out with respect to the substrate 4 for a predetermined period of time, the shutter 12a is closed. Next, the substrate 4 is again conveyed and stops when the portion on which the deposition has been carried out in the first deposition possible region 60a has reached the second deposition possible region 60b. The shutters 12a and 12b open, and the deposition is carried out again. Thus, the first layer is formed in the first deposition possible region 60a, and the second layer having a different growth direction from the first layer is formed as the deposited film on the first layer in the second deposition possible region 60b.
