Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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. 2 . The anode material according to claim 1 further comprising a catalyst that coats the hydrogen storing alloy. 3 . The anode material according to claim 2 , wherein the catalyst contains a noble metal element. 4 . The anode material according to claim 2 , wherein neither the hydrogen storing alloy nor the catalyst contains Ni. 5 . The anode material according to claim 1 , wherein the Cr content in the hydrogen storing alloy is 50 at % or less. 6 . A battery comprising a cathode, an anode, and an electrolyte layer that contains an aqueous liquid electrolyte and is formed between the cathode and the anode; wherein the anode is provided with the anode active material layer that contains the anode material according to claim 1 . 7 . The battery according to claim 6 , wherein the cathode is an air electrode.
