Higher capacity batteries

The batteries in Amateur Radio handhelds never seem to last long enough, but now a new storage material may provide the answer.

ScienceDaily reports that researchers at the Institute for Chemistry and Technology of Materials have developed a new method that utilises silicon for lithium-ion batteries.
Its storage capacity is ten times higher than the graphite substrate which has been used up to now, and promises considerable improvements for users.
