Abstract:
1. A method for producing a positive electrode for a non-aqueous electrolyte secondary cell, the method comprising the steps of: a baking step of baking a positive electrode active material precursor containing a lithium source and a nickel source in order to render the positive electrode active material precursor a lithium nickel composite oxide; a measuring step of measuring the amount of carbon dioxide gas generated when the lithium nickel composite oxide is heated to 200° C. or higher and 1500° C. or lower in an inactive gas atmosphere; a selecting step of selecting a lithium nickel composite oxide satisfying the following formulas: where x is a heating temperature (° C.) in the measuring step and y is the amount of carbon dioxide gas (mole/g) per 1 g of the lithium nickel composite oxide measured in the measuring step; and a positive electrode completing step of completing the positive electrode by using a positive electrode active material mainly made of the lithium nickel composite oxide selected in the selecting step.
