Samsung's latest patent promises graphene batteries that last longer, charge faster
17

Samsung has just received a patent for an odd 'graphene ball' invention that might be quite beneficial to smartphone batteries. Developed by SAIT (Samsung Advanced Institute of Technology), the invention introduces batteries with extremely high volumetric energy density, reportedly lasting roughly 45% more than their current-gen counterparts, which could easily become the next big breakthrough on the scene.
Finally, the graphene ball batteries are reportedly capable of maintaing workload temepratures of around 60 degrees Celsius, making them a prime candidate for use in future electric cars.
