Method for producing positive electrode for non-aqueous electrolyte secondary cell and method for producing non-aqueous electrolyte secondary cell |
摘要 |
A method for producing a non-aqueous electrolyte secondary cell by preparing a positive electrode by applying a positive electrode mixture onto a positive electrode core material, the mixture containing a positive electrode active material mainly made of a lithium nickel composite oxide and a binding agent containing polyvinylidene fluoride; measuring the amount of carbon dioxide gas generated when a layer of the positive electrode mixture is removed out of the positive electrode and the layer is heated to 200° C. or higher and 400° C. or lower in an inactive gas atmosphere; selecting a positive electrode satisfying the following formulas: y<(1.31x−258)/1000000(200≦̸x<300)  formula 3 y<1.20x−225/1000000(300≦̸x≦̸400)  formula 4 where x is a heating temperature (° C.) and y is the amount of carbon dioxide gas (mole/g) per 1 g of the lithium nickel composite oxide measured; and preparing the non-aqueous electrolyte secondary cell by using the positive electrode selected. |
