Video: Samsung to make batteries charge faster and last longer with new 3D graphene. People often credit their ideas to inexplicable eureka moments. But sometimes it’s just a matter of being in the right place at the right time. Almost two years ago, Rafa Terradas was thinking about developing an innovative bicycle, unlike anything else on the market. At the time, he was also collaborating with the Spanish National Research Council, CSIC, on a project using artificial intelligence and robotics to help autistic children communicate with their environment. There, he met members of the research group from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) dedicated to graphene, which is a super-thin material that’s stronger than steel, more conductive than copper, and flexible. The institute was then working on the storage of energy using grapheme. Tech entrepreneur Terradas, founder of startup builder Napptilus Tech Labs, saw an opportunity to develop graphene batteries for electric vehicles. The startup he created, Earthdas, has now developed a battery for charging electric bikes and motorcycles in just five minutes, at home and without the need for any specific installation. Ultimately, the technology could be used to enable really fast charging for larger vehicles, such as when they’re stationary at traffic lights. It uses paste-like electrolytes based on graphene, which improve “energy density capacity”, and offer a 12 times faster charging time than lithium-based equivalents, says Terradas. The first prototypes built by the company, located in the Pier01 of Barcelona, the hub hosting most of… [Read full story]
