Batteries made with silicon instead of graphite — the commonly used material in battery anodes today — have been shown to enable significantly higher energy density and faster charging.
“Silicon anode has 10 times higher energy density than graphite,” according to CEO Kang Sun of Amprius Technologies, one of the companies working on the technology.
“We’ve demonstrated that we can charge to 80 percent in under six minutes,” added Jon Bornstein, the company’s chief operating officer. Amprius is already working with Airbus, the U.S. Army, AeroVironment and BAE Systems on early iterations of its silicon-anode batteries.

Is it easy to switch battery production plants to a new method easily? I certainly hope so.
