description The invention relates to anodes of lithium ion batteries, the anodes comprising porous anode coatings with volumetric capacities of >= 800 mAh/cm3 and current collectors, the porous anode coatings being based on at least one active material (AM) in the form of particles, at least one binder, optionally graphite, optionally at least one other electroconductive component and optionally at least oneadditive, where the particles containing active material consist of at least 90 wt. %, in relation to the total weight of the particles containing active material, of an element selected from the group comprising silicon (Si), tin (Sn) and lead (Pb), characterized in that the porous anode coatings have a porosity [phi] in the region of 0.9*[phi]Opt
