Claim:
1. An anode for a lithium-ion battery comprising: a current collector; a separator; an active material layer between the current collector and the separator having a collector-facing surface, a separator-facing surface and side walls extending around a perimeter of the active material layer, the active material layer comprising alloying particles and a carbon material; and a conductive net of carbon material surrounding the active material layer on at least the side walls of the active material layer and the separator-facing surface of the active material layer, the conductive net having net openings sized to retain the alloying particles and the carbon material within the conductive net while allowing lithium ions and electrons to pass through, the conductive net maintaining electrical contact between the carbon material and the alloying particles during lithiation and delithiation of the alloying particles.
