Abstract
The invention relates to doped nickelate-containing compounds comprising AaM1VM2WM3XM4yM5ZO2-c wherein A comprises either sodium or a mixed alkali metal in which sodium is the major constituent; M1 is nickel in oxidation state greater than 0 to less than or equal to 4+, M2 comprises a metal in oxidation state greater than 0 to less than or equal to 4+, M3 comprises a metal in oxidation state 2+, M4 comprises a metal in oxidation state greater than 0 to less than or equal to 4+, and M5 comprises 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.
