Title: Electrode materials for sodium batteries

Abstract

The present invention provides an electrode material suitable for use as a cathode in a sodium electrochemical cell or battery, the electrode comprising a layered material of formula Na.sub.cLi.sub.dNi.sub.eMn.sub.fM.sub.zO.sub.b, wherein M comprises one or more metal cation, 0.24.ltoreq.c/b.ltoreq.0.5, 0 < d/b.ltoreq.0.23, 0.ltoreq.e/b.ltoreq.0.45, 0.ltoreq.f/b.ltoreq.0.45, 0.ltoreq.z/b.ltoreq.0.45, the combined average oxidation state of the metal components (i.e., Na.sub.cLi.sub.dNi.sub.eMn.sub.fM.sub.z) is in the range of about 3.9 to 5.2, and b is equal to (c+d+Ve+Xf+Yz)/2, wherein V is the average oxidation state of the Ni, X is the average oxidation state of the Mn, and Y is the average oxidation state of the M in the material. The combined positive charge of the metallic elements is balanced by the combined negative charge of the oxygen anions, the Na is predominately present in a sodium layer, and the Mn, Ni, and M are predominately present in a transition metal layer.
