MagniX, a U.S. electric propulsion systems developer, revealed plans to produce the new lithium-ion Samson range of batteries for aviation applications, AIN reported. The new batteries are expected to deliver an energy density of 300 watt-hours per kilogram, with a service life of over 1,000 discharge cycles. MagniX intends to use these batteries in energy storage for its family of electric propulsion systems with power ranging from 350 to 650 kilowatts.
