Abstract
A main object of the present disclosure is to provide a novel active material whose volume variation due to charge/discharge is small. The present disclosure achieves the object by providing an active material having a composition represented by NaMSi, wherein M is a metal element other than Na, x and y satisfy 0<x, 0≤y, y≤x and 0<x+y<8, and comprising a crystal phase of a Type I silicon clathrate.
