Sand-Based Battery Has Three Times the Capacity of Standard Li-Ion Cells

By Gary Cutlack on at

Engineering researchers at the University of California claim to have come up with a new lithium-ion battery tech that squeezes three times as much capacity into the space of one of today's cells, using nanoscale silicon formed from sand as part on the process.

The battery uses heavily processed sand that's milled and reduced down to an extremely pure nano-silicon form, a component that has a "sponge like consistency" ideal for improving battery density and, hopefully, tripling the power reserves we might see in some ideal future. [UCR via Azonano]
