<P>PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery made to have high energy density by arranging an extremely thin separation member, securing excellent safety due to an excellent shut-down effect, and a manufacturing method of the same. <P>SOLUTION: The nonaqueous secondary battery has a cathode, lithium, an anode having an anode activator capable of storing and releasing lithium alloy or lithium ion, and a porous separation member as constituents. The separation member formed on the cathode and/or the anode includes a first polymer having a softening point of not lower than 150°C and a second polymer having a softening point of not lower than 60°C and not higher than 150°C, and has a thickness of not thicker than 15 μm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
