POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE BATTERY, ITS MANUFACTURE, NONAQUEOUS ELECTROLYTE BATTERY USING THE POSITIVE ELECTRODE, AND MANUFACTURE OF THE BATTERY

摘要

PROBLEM TO BE SOLVED: To obtain a positive electrode having excellent discharge preserve characteristics, high temperature preserve characteristics, a high discharge actuating voltage and high energy density by suppressing self discharge, even if lithium manganate (LiMn2O4) is used for a main positive electrode active material. SOLUTION: This positive electrode is provided with spinel lithium manganate expressed by Li1+XMn2-YO4 (provided an atom ratio of lithium to manganese is 0.56<=Li/Mn=(1+X)/(2-Y)<=0.62, -0.2<=X<=0, 0.2 and Y<=1.0), mixed with at least one kind selected from lithium cobaltate expressed by Li1+ZCoO2 (-0.5<=Z<=0.5) or lithium nickelate expressed by Li1+ZNiO2 (-0.5<=Z<=0.5).
