Abstract
(EN)
The present disclosure provides a negative electrode material which is capable of improving the charge and discharge efficiency of a battery. A negative electrode material (1000) of the present invention contains a reduction product (101) of a first solid electrolyte material and a conductive assistant (103). The first solid electrolyte material (101) is represented by formula (1) LiαMβXγ. In formula (1), each of α, β and γ is a value larger than 0; M represents at least one element that is selected from the group consisting of metal elements other than Li and semimetal elements; and X represents at least one element that is selected from the group consisting of F, Cl, Br and I.
