Abstract

In this work showed the possibility of creation high capacity thin-film lithium batteries with the Si-CNT nanocomposite anodes. Synthesized multiwall carbon nanotubes were covered by amorphous silicon with magnetron sputtering. Developed method of formation nanostructured composite is simple, efficient and compatible with widely spread equipment. As s result, designed anode structures with deposited Si thickness of 260 and 390 nm exhibit high specific capacities (more than 2500 mAh/g) and significantly improved cycling stability versus silicon films.
