Samsung Dramatically Increases Battery Capacity (Nearly Doubles It)

Samsung researchers have developed a new technology that enables them to coat silicon battery cathodes with high crystal graphene. This means that they can now virtually double the capacity of lithium-ion batteries! This energy density increase could almost double the range of electric vehicles without adding a single pound of weight. This could also double the electric-mode range of plug-in hybrid cars, significantly reducing reliance on their built-in gasoline engines.
