"increase the battery’s discharge rate by a factor of 10 using innovative new materials that have yet to be used in batteries... eliminate 30 to 40 per cent of the battery’s weight, it also allows us to double or even triple the energy it can store, far exceeding the capabilities of lithium-ion batteries that are considered to be state of the art... experimental X-57 aircraft, nicknamed Maxwell, which replaces fuel-powered propellers with an all-electric propulsion system"
