1 more element
A method for producing a negative electrode material for a battery, the method comprising:
- a step of adding tungsten trioxide to a solution for dissolution to dissolve the tungsten trioxide;
- a step of dissolving silicon in the solution for dissolution in which the tungsten trioxide is dissolved;
- a step of removing a liquid component in the solution for dissolution in which the tungsten trioxide and the silicon are dissolved to produce a primary intermediate;
- a step of dissolving the primary intermediate and carbon in a liquid;
- and
- a step of removing a liquid component in the liquid in which the primary intermediate and the carbon are dissolved to produce the negative electrode material.
