Abstract
The invention relates to electrodes comprising doped nickelate-containing compositions comprising a first component-type comprising one or more components with an 03 structure of the general formula: AaM1V M2W M3X M4y M5Z O2 wherein A comprises one or more alkali metal selected from sodium, lithium and potassium; M1 is nickel in oxidation state 2+, M2 comprises one or more metals in oxidation state 4+, M3 comprises one or more metals in oxidation state 2+, M4 comprises one or more metals in oxidation state 4+, and M5 comprises one or more metals in oxidation state 3+ wherein 0.85≤a≤1; 0<v<0.5; at least one of w and y is >0; x≥0; z≥0; and wherein a, v, w, x, y and z are chosen to maintain electroneutrality; together with one or more component-types selected from a second component-type comprising one or more components with a P2 structure of the general formula: A′a′<M1′ V′ M2′ W′ M3′ X′<M4′ y′<M5′ Z′ O2 wherein A′ comprises one or more alkali metal selected from sodium, lithium and potassium; M1′ is nickel in oxidation state 2+, M2′ comprises one or more metals in oxidation state 4+, M3′ comprises one or more metals in oxidation state 2+, M4′ comprises one or more metals in oxidati…
