Samsung's Graphene Balls Promise Five-Times-Faster Battery Charging

By Gary Cutlack on at

Here's a new battery technology that doesn't sound like a fictional, thousand-years-away dream -- graphene balls. It's the latest thing from researchers at the Samsung Advanced Institute of Technology, who promise the dream of a full charge for your needlessly large smartphone in around 12 minutes.

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.

Hee's something about it that means literally nothing to us: "Its hierarchical 3D structure with the SiOx nanoparticle center allows even 1 wt% graphene-ball to be uniformly coated onto a nickel-rich layered cathode (LiNi0.6Co0.1Mn0.3O2) via mild Nobilta milling."

That sounds very hard, so it's probably still a decade away. [Samsung via FT]
