Abstract
A method of manufacturing a non-aqueous electrolyte secondary battery is provided wherein the positive electrode is made from a lithium-metal composite oxide represented by the general formula Li(Ni, Co)MO(0.98≦x≦1.10, 0.05≦y≦0.4, 0.01≦z≦0.2, in which M represents at least one element selected from the group consisting of Al, Mg, Mn, Ti, Fe, Cu, Zn and Ga), and having an average particle diameter of 5 μm to 10 μm a C-amount of 0.14 wt % or less measured by way of the high-frequency heating-IR absorption method, and a Karl Fischer moisture content of 0.2 wt % or less when heated to 180° C. and the method comprising the steps of applying a paste of active material for positive electrode to electrode plate to make an electrode, then drying the electrode, and pressing and then installing the electrode in a battery, in a work atmosphere having an absolute moisture content of 10 g/mor less.
