Abstract
A method for producing a negative electrode active material according to the present disclosure includes heat-treating a raw material mixture for the negative electrode active material at a temperature of more than 400° C. and less than 1,100° C. The negative electrode active material has a composition represented by Li3+x+αV1−xMxO4+α/2. M is at least one selected from tetravalent semi-metal elements and tetravalent metal elements excluding V. α and x satisfy 0.03<α<1.0 and 0≤x<1.
