Researchers at the Samsung Advanced Institute of Technology (SAIT) have managed to develop a "graphene ball" which could transform the way we think about batteries. In a statement on Tuesday, South Korean tech giant Samsung described the graphene ball as a "unique battery material" which allows a 45 percent increase in capacity, as well as charging speeds that are five times faster than standard lithium-ion batteries.

Electric sportscar startup Fisker (Anaheim, CA) has filed a patent for a 3D solid state battery structure that can charge in one minute (above). The design could hold 2.5 times the energy of today’s lithium ion cells and charges each layer simultaneously. However the patent has not been published, leading critics to highlight some of the potential problems. Charging a solid state battery pack with a 500 mile range in just one minute would take several megawatts of energy in a very short time, placing a huge, and unmeetable, requirement on the charging sub-systems and infrastructure. Transferring such large amounts of energy would also have safety implications.
