The company has provided lithium-ion batteries to military aircraft and high altitude unmanned aerial vehicles. EaglePicher also developed the first human-implantable lithium-ion battery. The company has nine North American manufacturing and research and development sites and over 900 employees.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
The company claims that the battery packs have an expected lifespan of 1500 hours and cost US$7000 each, with the aircraft carrying 3-5 battery packs, giving two to two and half hours endurance. The batteries can be recharged in 3–4 hours from a 220 volt outlet.
In January 2020, Wright Electric revealed that it was constructing a 1.5 MW electric motor and 3 kV inverters intended to power a 186-seat Wright 1 aircraft with a range of at least 300 nmi (560 km) that could enter into service from 2030. Ground testing of the motor is planned for 2021 and flight testing for 2023.
It is powered by a 345 VDC, 20 kWh battery pack, in two 70 kg (150 lb) each, liquid-cooled lithium batteries by Pipistrel, connected in parallel for fault tolerance. [1] [2] [7] One battery is mounted in the nose and one behind the cabin for balance. They take 2 hours to recharge from 30% to 100% capacity, and allow an endurance of up to 50 ...
Lilium invested in Ionblox for its silicon-dominant anode battery technology, which it believes offers uniquely high energy and power density (12C with 3.8 kW/kG at 50% charge and 3.0 kW/kG at 30%) needed for hover and take-off phases, even at low charge levels. [14] The target range is 280 km (150 nmi).
