Samsung develops ‘graphene ball’ to speed up battery charging
#SamsungElectronics’ research arm has successfully synthesized a ” #grapheneball” that can be used to make #lithiumion batteries last longer and charge faster, the company has said. @Samsung Advanced Institute of Technology ( #SAIT ) said using graphene ball material to make batteries will increase their capacity by 45 percent and increase their charging speed by five times. Current lithium-ion batteries take an hour to fully charge but this will be reduced to 12 minutes with the new tech, Samsung said. Batteries that use graphene ball can also maintain a temperature of 60 degrees Celsius that is required for use in electric cars, the company added.
