Abstract: The present invention provides anode materials, methods of producing them, anodes, methods of producing them, electrochemical cells, and lithium-ion batteries, where the anode material comprises a silicon monoxide nanoparticle. In certain embodiments, the silicon monoxide is porous or mesoporous. In certain embodiments, the porous or mesoporous silicon additionally comprises other materials within its pores, such as lithium.
Abstract: The present invention provides electrochemical cells and batteries having one or more electrically conductive tabs and carbon sheet current collectors, where the tabs are connected to the carbon sheet current collectors; and methods of connecting the tabs to the carbon based current collectors. In one embodiment, the electrically conductive tabs are metallic tabs.
