NOVELTY - An active material for a positive electrode for a non-aqueous electrolyte secondary battery, comprises a lithium-metal composite oxide.    USE - For a positive electrode for a non-aqueous electrolyte secondary battery.    ADVANTAGE - The material provides the non-aqueous electrolyte secondary batteries with high initial discharge current and low irreversible capacity (retention), and with high output characteristics at high and/or low temperatures. It allows increased capacity, improved Coulomb efficiency, reduced irreversible capacity, improved output at low temperature, and improved cycle characteristics in the non-aqueous electrolyte secondary batteries.    DETAILED DESCRIPTION - An active material for a positive electrode for a non-aqueous electrolyte secondary battery, comprises a lithium-metal composite oxide. An active material for a positive electrode for non-aqueous electrolyte secondary battery, comprises a lithium-metal composite oxide represented by the formula: Lix(Ni1-yCoy)1-zMzO2 or Lix(Ni1-y'Coy)1-zMzO2. It has a C-amount of at most0.14 wt.% measured by way of the high-frequency heating-infrared absorption method, and a Karl Fischer moisture content of at most 0.2 wt.% when heated to 180 degrees Celsius.    x = at most 0.98 and at least 1.10;    y = at most 0.05 and at least 0.4;    z = at most 0.01 and at least 0.2; and    M = element(s) from Al, Mg, Mn, Ti, Fe, Cu, Zn or Ga.    INDEPENDENT CLAIMS are also included for:    (a) a manufacturing process for the positive electrode;    (b) a non-aqueous electrolyte secondary battery prepared by using the above active material and assembled in a work atmosphere having an absolute moisture content of at most 10 g/m3 for assembling;    (c) a method of manufacturing the non-aqueous electrolyte secondary battery where the positive electrode is made from the above lithium metal composite oxide, comprising an assembling step conducted in the work atmosphere having an absolute moisture content of at most 10 g/m3.    DESCRIPTION OF DRAWING(S) - The figure is a graph showing a relation between an output at low temperature, a C-amount and an absolute humidity in the atmosphere in which an electrode is manufactured.
