Abstract
A rechargeable electrochemical cell comprising a negative electrode and a positive electrode is described. The positive electrode comprises a product having as overall formula Lip(NiMnCoMAlA)O, wherein M signifies one or more elements from the group Mg, Ti, Cr, V and Fe, wherein A signifies one or more elements from the group F, C, Cl, S, Zr, Ba, Y, Ca, B, Sn, Sb, Na and Zn, and wherein 0.9<(x+y+z+m+n+a)<1.1, b<0.02, 0.9<p<1.110, 0.30<x<0.95, (y+z)≥0.09, 0≤m≤0.05, 0≤a≤0.05, and 0≤n≤0.15. The negative electrode comprises composite particles, wherein the composite particles comprise silicon-based domains in a matrix material. The individual silicon-based domains are either free silicon-based domains that are not or not completely embedded in the matrix or are fully embedded silicon-based domains that are completely surrounded by the matrix material.
