The invention relates to novel materials of the formula: A1-δNi0.5M10.5-xM2xO2 wherein A comprises one or more alkali metals selected from lithium, sodium and potassium; M1 and M2 each comprise a metal in oxidation state +4 selected from one or more of manganese, titanium and zirconium; further wherein 0≦̸δ≦̸0.1; X is in the range 0≦̸X<0.5; wherein when X=0 then M1≠Mn or Ti. Such materials are useful, for example, as electrode materials in sodium ion and/or lithium ion and/or potassium ion battery applications. |
