If this new anode design was combined with new concepts for lightweight versions of the cathode, such as one already proposed previously by Li, this work could lead to substantial reductions in the overall weight of lithium-ion batteries, say the researchers. For example, the researchers hope it could lead to cellphones that could be charged just once every three days, without making the phones any heavier or bulkier.
