Abstract
Disclosed are methods of safely producing a high quality negative electrode material composed of a mixture of a non-carbon material and a carbon material, a negative electrode using the negative electrode material, and a non-aqueous electrolyte battery using the negative electrode. The high quality negative electrode is produced by pulverizing and classifying each of the non-carbon material and the carbon material in an inert gas atmosphere, and further mixing them to each other in an inert gas atmosphere.

A method of producing a negative electrode material composed of a mixture of a non-carbon material and a carbon material, comprising the step of:
- pulverizing and classifying each of the non-carbon material and the carbon material in an inert gas atmosphere.
A method of producing a negative electrode material composed of a mixture of a non-carbon material and a carbon material, comprising the step of:
- mixing the non-carbon material and the carbon material in an inert gas atmosphere.
A method of producing a negative electrode by applying a negative electrode black mix containing a negative electrode material composed of a mixture of a non-carbon material and a carbon material on a negative electrode collector and drying the negative electrode black mix, comprising the step of:
- applying the negative electrode black mix on the negative electrode collector and drying the negative electrode black mix in an inert gas atmosphere or a dry air atmosphere.
A method of producing a negative electrode using a negative electrode black mix containing a negative electrode material composed of a mixture of a non-carbon material and a carbon material, comprising the step of:
- hot-pressing the negative electrode black mix.
A method of producing a non-aqueous electrolyte battery, including a positive electrode containing a lithium composite oxide;
- a negative electrode containing a negative electrode material composed of a mixture of a non-carbon material in or from which lithium is doped or released and a carbon material, said negative electrode being disposed opposite to the positive electrode;
- and a non-aqueous electrolyte interposed between the positive electrode and the negative electrode, said method comprising the step of:
- winding the negative electrode into a wound body in an inert gas atmosphere or a dry air atmosphere.
A method of producing a non-aqueous electrolyte battery, including a positive electrode containing a lithium composite oxide;
- a negative electrode containing a negative electrode material composed of a mixture of a non-carbon material in or from which lithium is doped or released and a carbon material, said negative electrode being disposed opposite to the positive electrode;
- and a non-aqueous electrolytic solution used as a non-aqueous electrolyte interposed between the positive electrode and the negative electrode, said method comprising the step of:
- pouring the non-aqueous electrolytic solution in the non-aqueous electrolyte battery in an inert gas atmosphere or a dry air atmosphere.
