Abstract
An object of the present disclosure is to provide an anode material with a high capacity maintenance rate. To achieve the above object, the present disclosure provides an anode material to be used for a battery that contains an aqueous liquid electrolyte, the anode material comprising: a hydrogen storing alloy that reversibly stores and releases hydrogen; wherein the hydrogen storing alloy contains Ti, Cr, and V as main components, and is an alloy that contains a BCC phase as a main phase; a lattice constant of the BCC phase is 3.01 Å or more and 3.10 Å or less; and the Cr content in the hydrogen storing alloy is 20 at % or more.
