<P>PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery with a high capacity and a long life. <P>SOLUTION: The nonaqueous secondary battery is provided with an anode having an anode mix layer containing a specific high-capacity material or carbon particles on both sides of a support, and a cathode having a cathode mix layer containing a lithium composite oxide on both sides of a support. The support of the anode and the support of the cathode include through-holes penetrating from one side to the other side. And also, the support of the anode structured of rolling copper, non-electrolytic copper or a copper alloy, or the support of the cathode structured of aluminum or an aluminum alloy, has a thickness from 20 to 40 μm, a hole area ratio from 30 to 70%, and a tensile strength from a 5 to 30 N/15 mm width. <P>COPYRIGHT: (C)2008,JPO&INPIT |
