Abstract (en)

[origin: WO2021121714A1] An active substance composition comprising: a) a lithiated iron manganese phosphate of formula LixMn1-y-zFeyMzPO4 in which M is selected from the group consisting of B, Mg, Al, Si, Ca, Ti, V, Cr, Co, Ni, Cu, Zn, Y, Zr, Nb and Mo, alone or as a mixture, with 0.8 ≤ x ≤ 1.2; 1-y-z > 0.5; 0.5 > y ≥ 0.05 and 0 ≤ z ≤ 0.2; and b) at least one crosslinked or non-crosslinked polymer selected from: i) a hydrogenated butadiene-acrylonitrile copolymer comprising from 10 to 60% by mass of acrylonitrile units and containing a molar percentage of residual double bonds of from 0.5 to 20%, ii) a carboxylated butadiene-acrylonitrile copolymer comprising from 10 to 60% by mass of acrylonitrile units and containing a molar percentage of residual double bonds of from 0.5 to 20%, iii) a mixture thereof.
