The use of tin-decorated mesoporous carbon as an anode material for rechargeable lithium batteries

A sonochemical process has been developed for the insertion of tin nanoparticles into mesoporous carbon, giving a product which was used as a building block for the anode of a rechargeable Li battery; the electrode could deliver a reversible capacity of 400 mAh gr(-1) (C + Sn) at 100% cycling efficiency, which is higher than that of graphite electrodes.
