Chemists in Canada have used a carbon framework to form an electrode in lithium-sulfur batteries that results in charge capacities several times greater than standard lithium ion batteries.
The researchers say that the electrode, which is based on a framework of ordered carbon rods and fibres, behaves like a 'mini electrochemical reaction chamber.'
