While the values for an electric motor are desirable, a propulsion system on an aircraft also needs to be compared relative to the weight of the energy source carried onboard, which is contained in the batteries.
NASA and its industry partners are exploring six different electrical propulsion architectures for electrified aircraft concepts, including an all-electric system configuration, three hybrid electric system configurations, and two turboelectric system configurations All-electric aircraft systems use batteries as the only source of propulsion power.

For an electric propulsion system, the use of many fans lowers the power required of each motor. This potentially makes the aircraft practical sooner, as smaller motors can be used instead of waiting for the development of larger motors. Partial turboelectric systems are also being studied.
Batteries have been proposed for powering electric aircraft, either as stand-alone systems or hybridized with other power generation systems. Batteries offer modular building blocks for a wide variety of operational concepts in centralized or distributed power systems.
The key challenge to battery-powered propulsion systems for aviation is to increase battery specific energy. Current lithium-ion battery cells typically achieve 150-250 Wh/kg, while commercial lithium-sulfur cells currently achieve over 350 Wh/kg.
