Smartphone batteries with twice the life may arrive in 2017
A type of lithium battery that could make gasoline-powered cars obsolete is on track to be commercialized, according to MIT News. The "lithium metal" batteries, developed by MIT spin-off SolidEnergy, can reportedly pack the same energy as a standard lithium-ion cell in half the size. "Or, we can make a battery the same size as a lithium ion battery, but now it will last twice as long," says SolidEnergy CEO Qichao Hu.
