Graphene and Tin composite material can be used to make better battery electrodes

Researchers from the Lawrence Berkeley National Laboratory have created a graphene and tin composite material that can be used to make battery electrodes. Tin turns into nanopillars when heated at 300 degrees - and these nanopillars 'widen the gap' between graphene layers. This leads to better performing electrodes (faster charging).

This is still an early stage technology - current prototypes only last for about 30 charge cycles.
