Samsung's new 'graphene ball' tech promises 5x faster battery charging
28 Novembre, 2017, 01:05 | Auteur: Therese Cote
There's a research paper you can read if you can handle all the terminology, although the bottom line is that it claims a battery capacity increase of 45 per cent within a comparable size as today's cells, along with that five-fold increase in charging time, because of. graphene magic. "Batteries that use graphene ball can also maintain a temperature of 60 degrees Celsius that is required for use in electric cars".
For a battery that takes an hour to fully charge, the usage of graphene ball will reduce charging time to as little as 12 minutes. The team successfully synthesized graphene the so-called balloon, which potentially can be used for the production of batteries support much faster charging than now. They then used the obtained graphene balls as a material for the anode and the cathode in traditional Li-ion batteries.
