LAYERED OXIDE MATERIALS FOR BATTERIES

WIPO Patent Application WO/2016/103649

A1

Materials are presented of the formula: Ax My Mi zi O2-d, where A is sodium or a mixed alkali metal including sodium as a major constituent; x > 0; M is a metal or germanium; y > 0; Mi, for i = 1, 2, 3...n, is a transition metal or an alkali metal; zi >= 0 for each i = 1, 2, 3...n; 0 < d <= 0.5; the values of x, y, zi and d are such as to maintain charge neutrality; and the values of x, y, zi and d are such that x + y + Summation zi > 2-d. Also presented is a method of preparing a compound having the formula Ax My Mi zi O2-d.
