<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery which has an excellent adhesion of a negative electrode active material mixture layer to a negative electrode core and is superior in discharge load characteristics and capacity maintenance rate. <P>SOLUTION: The non-aqueous electrolyte secondary battery 10 is provided with a wound electrode body which has a negative electrode plate 12 in which a negative electrode active material mixture layer is provided on a surface of a negative electrode core and a positive electrode plate 11 in which a positive electrode mixture layer is provided on the surface of a positive electrode core, and the negative electrode plate 12 and the positive electrode plate 11 are respectively wound through a separator. The negative electrode active material mixture layer is provided with a first negative electrode active material mixture layer which uses NH<SB>4</SB>of CMC as a thickener formed on the surface of the negative electrode core and a second negative electrode active material mixture layer which uses at least one kind selected from CMC-Na and CMC-Li as a thickener formed on the surface. <P>COPYRIGHT: (C)2009,JPO&INPIT |
