New Lithium Battery Triples Capacity and Charges Fully in Just Ten Minutes

The number one technological hurdle separating humanity from the Jetson Future we deserve is developing a reliable power supply. Even today, we’re barely even able to keep out phones alive through the evening commute. But a radical departure in Lithium ion battery technology could help keep our power-hungry gadgets online for days, not hours.

Conventional Lithium ion batteries, the rechargeable cells what power everything from phones to Priuses, generate current by shuttling positive lithium ions between microscopically thin sheets of carbon graphite located at each electrode. But as these sheets age, their capacity and discharge performance degrades. This is especially true in the new generation of lithium-silicon cells (silicon replacing toxic cobalt as the battery’s anode)—the mechanical stress of accepting and discharging electrons causes these silicon sheets to crack over time.
