Beschreibung
Zusammenfassung:	A method for manufacturing an anode active material and/or an anode for a lithium cell and/or lithium battery, in particular for a lithium-ion cell and/or lithium-ion battery, and/or for manufacturing such a lithium cell and/or lithium battery. In order to improve the cycle stability of the lithium cell and/or lithium battery, in the method at least one polymerizable monomer, and/or at least one polymer constituted from the at least one polymerizable monomer, is reacted with at least one silane compound having at least one polymerizable and/or polymerization-initiating and/or polymerization-controlling functional group, and anode active material particles, in particular silicon particles, are added. Also described is an anode active material, an anode, and a lithium cell and/or lithium battery.
