Nasa invents ‘incredible’ battery for electric planes

Nasa has invented a new type of high-performance battery that researchers claim could be used to power fully electric airplanes.
The US space agency made the breakthrough following
investigations into solid-state batteries, which hold more energy and are
lighter than industry-standard lithium-ion batteries.
Solid-state batteries also perform better in stressful
environments, as they are less prone to overheating, fire and loss of charge
over time, however they typically cannot discharge energy at the same rate as
li-ion batteries.
Until now, this has made them unsuitable for powering large
electronics, such as electric vehicles, as they require batteries capable of
discharging their energy an incredibly fast rate.
This issue was solved by researchers at Nasa’s Solid-state
Architecture Batteries for Enhanced Rechargeability and Safety (SABERS) unit,
who were able to increase the battery’s discharge rate by a factor of 10 using
innovative new materials that have yet to be used in batteries.
A novel vertical-stack design also allowed SABERS researchers to
create a solid-state battery capable of powering objects at a capacity of 500
watt-hours per kilogram – roughly double that of an electric car.
“The possibilities are pretty incredible,” said Rocco Viggiano,
principal investigator for SABERS at Nasa’s Glenn Research Center in Cleveland.
“We’re starting to approach this new frontier of battery
research that could do so much more than lithium-ion batteries can... Not only
does this design eliminate 30 to 40 per cent of the battery’s weight, it also
allows us to double or even triple the energy it can store, far exceeding the
capabilities of lithium-ion batteries that are considered to be state of the
art.”
The new battery has already generated interest from government,
industry and academia, with SABERS researchers partnering with several
organisations to continue developing the technology.
The ultimate aim is to use it to pioneer a new era of
sustainable aviation that eliminates carbon emissions and noise from planes.
Nasa has already made significant progress in this area through
its experimental X-57 aircraft, nicknamed Maxwell, which replaces fuel-powered
propellers with an all-electric propulsion system.
