<P>PROBLEM TO BE SOLVED: To provide an electrode for a battery, suitable for a lithium-ion battery or the like with improvement in cycling characteristics, such as an initial discharge capacity and a capacity maintenance ratio, taking into consideration the problems incurred in case an anode active material layer is formed as a collector is made to travel, and to provide its manufacturing method with high productivity, as well as, a secondary battery that uses the electrode. <P>SOLUTION: The electrode for the battery is manufactured that contains an active material with a large energy capacity, such as silicon and tin, in an anode active material layer. Here, an anode collector 12 is arranged at a travelling mechanism consisting of a circular roll or the like, and a region located in an evaporation region A is made adhered to the circular roll 4 by a suctioning means or the like. Next, after tension on the anode collector 12 is put off, a film is formed on this region. After that, the anode collector 12 is made to travel for a given distance by the travelling mechanism, and the next active material layer forming region is moved to the evaporation region A. With the repeating of these series of processes, an active material layer is formed on a long anode collector 12. <P>COPYRIGHT: (C)2008,JPO&INPIT |
