<P>PROBLEM TO BE SOLVED: To provide a negative pole plate for a non-aqueous electrolyte secondary cell excellent in cycle characteristics, a manufacturing method therefor, and a non-aqueous electrolyte secondary cell. <P>SOLUTION: The negative pole plate for a non-aqueous electrolyte secondary cell is formed with a negative pole mixture layer that includes a negative active substance composed of a carbonaceous material, on the surface of a negative pole axis body, wherein the negative pole mixture layer includes at least two layers, a negative pole mixture layer of a first layer on the negative pole axis body side contains lithium with higher concentration than that of a negative pole mixture layer of another layer, and the volume shared by the negative pole mixture layer of the first layer is 30 to 65 percent of that of the entire negative pole mixture layer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
