<P>PROBLEM TO BE SOLVED: To provide a laminated secondary battery in which high energy density and high capacity are achieved at low cost, wherein the secondary battery is superior in battery characteristics and reliability, and is easy to respond to diversity of electrode mounting positions; and to provide a manufacturing method. <P>SOLUTION: In the laminated secondary battery, a positive electrode and a negative electrode are opposedly laminated via a separator, and housed in a container together with electrolytic liquid. In the positive electrode and the negative electrode, by thermal crimping molding using a press die, a positive electrode active material layer and a negative electrode active material layer are formed on a surface of a current collector, and a tab bonding part is constituted by installing a region in which the positive electrode active material layer and the negative electrode active material layer are not formed yet. <P>COPYRIGHT: (C)2011,JPO&INPIT |
