Lithium-silicon batteries get vote of confidence with Sila’s Mercedes deal

For years, scientists and engineers predicted that lithium-ion batteries would get a boost if they could just add more silicon. In the lab, the prediction held, but only for a short period of time. The material had a downside — it became brittle after repeated charging.
Sila seems to think it’s solved the problem. The startup, along with its strategic partner Mercedes-Benz, announced that its silicon anode material is scheduled to appear in an electric G-Class in 2025. That suggests not only that is Sila confident that its technology can meet the automaker’s high requirements, but also that it
