Abstract (en)
[origin: WO2018233963A1] A sacrificial positive active material for a lithium-ion electrochemical element which is a compound of formula (Li2O)x (MnO2)y (MnO)z (MOa)t in which: x+y+z+t=1; 1-x-y ≥ 0; 0.97 ≥ x ≥ 0.6; y ≤ 0.45. x –0.17; y ≥ 0; y+z > 0; t ≥ 0; 1 ≤ a < 3. M is selected from the group consisting of Fe, Co, Ni, B, AI, Ti, Si, V, Mo, Zr and a mixture thereof.
