One of Prof. Sadoway's postdocs, Qichao Hu, is preparing to commercialize a new lithium battery with double the capacity of modern models.
"The battery essentially swaps out a common battery anode material, graphite, for very thin, high-energy lithium-metal foil, which can hold more ions — and, therefore, provide more energy capacity. Chemical modifications to the electrolyte also make the typically short-lived and volatile lithium metal batteries rechargeable and safer to use. Moreover, the batteries are made using existing lithium ion manufacturing equipment, which makes them scalable." - MIT News
