Negative electrode material for non-aqueous electrolyte secondary battery and method for producing the same |
摘要 |
A method for producing a negative electrode material for a non-aqueous electrolyte secondary battery is disclosed: which includes a step of applying a shearing force to an intermetallic compound under the presence of nitrogen. The intermetallic compound contains element(A) which reacts with nitrogen and forms a nitride, but does not react with lithium, and element(B) which does not react with nitrogen, but reacts with lithium, thereby forming a mixture containing a nitride of element(A) and a substance of element(B).
