Abstract (en)
[origin: WO2022090267A1] The present invention relates to an electrode comprising a current collector formed by a metal strip which is coated on at least one of the faces thereof with a composition of electrochemically active materials, the composition comprising at least one lithium manganese iron phosphate having the following formula: LixMn1-y-zFeyMzPO4 , where 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 in a mixture, with 0.8 ≤x ≤ 1.2; 0.5 ≤ 1-y-z < 1; 0.05 ≤ y ≤ 0.5 and 0 ≤ z ≤ 0.2; the current collector having undergone chemical pickling of at least one of the faces thereof.
