New Airbus lab in Shenzhen to push battery technology for electric aerial vehicles; collaboration with BYD
In China, the recently opened Airbus China Innovation Center (ACIC) battery lab is looking to power a new generation of electric-powered aerial vehicles.
Asia is the global epicenter of battery development and production, with Japan and Korea as the worldwide leaders. However, China is rapidly catching up to the traditional heavyweights. China’s ascension to battery development superpower has been vertiginous—the country is expected to produce 70% of the world’s EV batteries by 2021.
This is why Airbus has selected the Airbus China Innovation Center (ACIC) in Shenzhen as the location for a new battery lab. Opened in August 2019, the lab will not only tap into the rich ecosystem of Shenzhen—China’s tech hub but also into the ecosystem across China and Asia to test batteries for a range of applications, from electric propulsion to electrical systems.
Despite the impressive progress made in recent decades, the untapped potential of batteries still remains significant. This includes the development of new materials and chemical combinations. The ACIC battery lab is focused on tapping into these possibilities, in addition to running safety and durability tests, and finding solutions to long-standing battery challenges.
One challenge is thermal runaway. Thermal runaway is an unstoppable chain reaction in a battery that causes rapid overheating and can lead to fire. It is rare, but can happen to computers or phones. In 2016, millions of electronic devices had to be recalled after a battery fault caused units to overheat and explode. Although lithium-ion is considered the most effective technology currently available for rechargeable batteries, the battery recalls are a reminder that it is not without safety concerns, which limits its use in aviation.
To develop new battery solutions that can be applied to commercial aviation, the ACIC team will collaborate with local partners in Shenzhen, including BYD, one of the world’s largest electric vehicle and battery makers. The team will also work closely with the Airbus Battery CoC, the TEIE team in Toulouse that develops new battery solutions for aerospace applications.
Having a battery lab in China is the perfect complement to our electrical lab in Toulouse. The ACIC lab will focus on testing the latest cells and battery technologies to emerge from China, which will reduce time to market.—Valéry Gineste, Head of TEIE
If the aviation industry is to drive progress on the electrification of flight, improving the safety and performance of batteries is crucial. Specifically, the success of urban air mobility and hybrid-electric future aircraft hinges on the development of high-performance and safe battery technology. This is a core focus for the ACIC battery lab, which will work to develop batteries for electric propulsion, a prerequisite to power this new class of aerial vehicles.
Better batteries will help to enable tomorrow’s aerial vehicles. New urban air vehicles, as seen in the case of Vahana and CityAirbus, will require batteries that are not only extremely light and powerful, but also reliable and cost efficient.—Mustang Guo, ACIC Project Manager
The ACIC battery lab will also look at how to safely replace nickel cadmium with superior lithium-ion batteries to power aircraft systems, without the need for restrictive heavy casing.
Further exploration areas will soon follow as the lab quickly ramps up the scope of its work.
