In news that could greatly extend the range of electric cars, researchers have shown that replacing the conventional graphite electrodes in lithium-ion batteries with silicon nanotubes can produce a battery that can store ten times more charge. The researchers developed a silicon anode that, aside from extending the range of electric cars, could also make gasoline-electric hybrid vehicles more efficient by allowing them to run in electric mode for longer periods.
