Manufacturers are showing it is feasible to design practical all-electric aircraft, but the constraints on their size and range will be relaxed only if batteries can advance beyond the current severe limitations on their performance. The battery field is littered with broken promises, but several next-generation designs are in the early stages of commercialization that offer higher energy density than today’s lithium-ion (Li-ion) models—a crucial parameter for aircraft. Options ...
