Abstract
Electrode materials for Li-ion batteries, Na-ion batteries, or K-ion batteries. Provided are materials that show enhanced capacity towards Li, Na, or K reactivity represented by formula AxTM1yTM2zSaClb, A being Li, Na, or K, TM1 and TM2 being 3d (Ti, V, Cr, Mn, Fe, Co, Ni, Cu), 4d (Nb, Mo, Ru, Rh) or 5d (W, Re, Os, Ir) transition metals, and x, y, z, a, and b being numbers of atoms. Also disclosed are batteries comprising the electrode materials.
Claims20
An electrode material having the formula AxTM1yTM2zSaClb, wherein A is Li, Na, or K, TM1 and TM2 are the same or different and are each selected from a 3d, 4d, and 5d transition metal, x is 0 to 2.5, the sum of y and z is 1, the sum of a and b is 3, and b is greater than 0.
