Abstract
Official abstract text for this publication.
Disclosed are a cathode materials suitable for an aluminium ion battery, wherein the cathode materials comprise a main group element nitride, and an oxide of a main group element or an oxide of a element in Group 1 to 13. The nitride is preferably a 2-dimensional layered material. Preferably, the ratio of the main group element nitride to the oxide is between 5:95 and 95:5 (by weight).
First claim
Opening claim text (preview).
What we claim is: 1 . A cathode for an aluminium ion battery comprising an active material, the active material comprising an oxide of boron, the oxide of boron comprising at least 75% (by weight) of the active material. 2 . The cathode of claim 1 , wherein the active material further comprises a boron nitride. 3 . The cathode of claim 2 , wherein a ratio of the oxide of boron to the boron nitride is between 5:95 and 95:5 (by weight). 4 . The cathode of claim 2 , wherein a ratio of the oxide of boron to the boron nitride is about 1:1 (by weight). 5 . The cathode of claim 1 , wherein the oxide of boron comprises boric anhydride. 6 . The cathode of claim 2 , wherein the boron nitride comprises a 2D layered material. 7 . The cathode of claim 2 , wherein the boron nitride comprises hexagonal boron nitride. 8 . The cathode of claim 1 , further comprising a conductive material. 9 . The cathode of claim 8 , where in the conductive material comprises conductive carbon. 10 . An aluminum ion battery cell comprising a cathode of claim 1 and an anode, wherein the anode comprises aluminum, an electrolyte in electrical contact with the anode and/or cathode, and optionally an ion permeable separator located between the anode and the cathode. 11 . A cathode for an aluminum ion battery comprising an active material, the active material comprising a main group element nitride, and an oxide of a main group element, wherein a ratio of the oxide of a main group element to the main group element nitride is between 5:95 and 95:5 (by weight). 12 . The cathode of claim 11 , wherein the main group element nitride is selected from a nitride of boron, carbon, aluminum, and silicon, and wherein the oxide of a main group element is an oxide of boron. 13 . An aluminum ion battery cell comprising the cathode of claim 11 and an anode, wherein the anode comprises aluminum, further comprising an electrolyte in electrical contact with the anode and/or cathode, and optionally an ion permeable separator located between the anode and the cathode.
