Discussion

Bluesky: @volts.wtf David Roberts · 1d ago · 199 ♥ Today on Volts: in lithium-ion batteries, the cathode has been evolving for 30 years, but the anode has remained stubbornly graphite. Now silicon anodes, which promise 5X the energy density & charging speeds, are finally reaching commercial viability.
