Farasis Batteries With Silicon-Carbon Anode Get 25% Energy Boost
The new cells with Group14’s silicon-carbon anode reach 330 Wh/kg and 750 Wh/l.

Group14 Technologies, a Washington state based battery material startup founded in 2015, reports that its SCC55 silicon-carbon anode provides a significant 25% energy density boost.
Farasis Energy, a Chinese battery manufacturer, was able to utilize the SCC55 to increase the energy density of its lithium-ion EV pouch battery cells to 330 Wh/kg, which is almost 27% more than 260 Wh/kg achieved when using a traditional graphite anode.
The volumetric energy density is also high at 750 Wh/l and the cycle-life is “more than 1000 charge-discharge cycles.”
Those are serious numbers, delivered from a respectable company. Let’s recall that Farasis Energy is a well known name in the battery industry, backed by Daimler, which has owned about 3% of the company since 2020. It supplies batteries for Mercedes-Benz and Geely.
Group14 Technologies, on the other hand, is backed by Amperex Technology Limited (ATL), BASF, Cabot Corporation, Showa Denko and SK materials.
According to the press release, Group14 Technologies is ready to deliver the SCC55 from its “commercial-scale” Battery Active Materials (BAM) factory in Washington state.
Dr. Keith Kepler, CTO of Farasis Energy said:
The confirmation that the SCC55 silicon-carbon anode works as expected in EV-sized cells is not a big surprise, as we first heard about Farasis Energy’s development of sample cells in Spring 2021.
At the time, the company highlighted (source in German) several parameters of its upcoming Gen4 cells:
The only person who got all his work done by Friday was Robinson Crusoe.
Anything i post over three lines long please assume it is an article lol.
