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 aircraft seats two. [26] It will have a range of 100 mi (160 km) and a maximum flight time of approximately one hour. The X-57's designers hope to reduce by five-fold the energy necessary to fly a light aircraft at 175 mph (282 km/h; 152 kn). [14] A threefold reduction should come from the switch from piston engines to battery-electric. [21]
The 787 battery contract was signed in 2005, [27] when LiCoO 2 batteries were the only type of lithium aerospace battery available. Still, since then, newer and safer [ 28 ] types (such as LiFePO 4 ) and LiMn 2 O 4 (lithium manganate), which provide less reaction energy during thermal runaway , have become available.
In 2017, a second pressurized model was to be an extended-range ER executive aircraft available by 2023 for $2.9 million, with a more powerful aluminum-air battery with a lithium-polymer buffer, a cabin pressurized to 1,200 m (4,000 ft) at FL 280, G5000 avionics, a 444 km/h (240 kn) cruise and 1,367 km (738 nmi) range.

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).
The Zephyr is a series of high-altitude platform station aircraft produced by Airbus. They were designed originally by QinetiQ, a commercial offshoot of the UK Ministry of Defence. In July 2010, the Zephyr 7 flew for 14 days. In March 2013, the project was sold to Airbus Defence and Space. In the summer of 2022, the Zephyr 8/S flew for 64 days.
For the record: 7:04 a.m. Oct. 28, 2024: An earlier version of this article said a lithium-ion battery fire occurred on Interstate 15 near Bakersfield.It was near Baker. For more than two days, a ...
As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032.
