Abstract

The invention relates to doped nickelate-containing compounds comprising AMMMMMOwherein A comprises either sodium or a mixed alkali metal in which sodium is the major constituent; Mis nickel in oxidation state greater than 0 to less than or equal to 4+, Mcomprises a metal in oxidation state greater than 0 to less than or equal to 4+, Mcomprises a metal in oxidation state 2+, Mcomprises a metal in oxidation state greater than 0 to less than or equal to 4+, and Mcomprises a metal in oxidation state 3+ wherein 0≤a<1, v>0, at least one of w and y is >0 x≥0, z≥0 wherein c is determined by a range selected from 0<c≤0.1 and wherein (a, v, w, x, y, z and c) are chosen to maintain electroneutrality.
