NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND POSITIVE ELECTRODE SHEET FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode sheet for a nonaqueous electrolyte secondary battery excellent both in weight energy density and weight output density, further excellent in cycle characteristics.SOLUTION: The positive electrode sheet for a nonaqueous electrolyte secondary battery is composed of a composite having on a collector a positive electrode active material layer containing (a) a conductive polymer and (b) at least one kind selected from a specific polycarboxylic acid and metal salt thereof. The conductive polymer is either in a de-doped state or in a reduced de-doped state.SELECTED DRAWING: Figure 6
