Airbus Defence and Sion Power Corporation signed a three-year collaborative agreement in order to which Sion Power will supply proprietary lithium sulfur (Li-S) batteries for use in Airbus Defence and Space’s Zephyr High Altitude Pseudo-Satellite (HAPS) aircraft.
The agreement extends the previously successful Zephyr 7 program in which Sion Power batteries were employed during the night, along with solar power during the day, to achieve record-breaking flights of more than 14 days without refueling or landing.
A few words about Zephyr
The Zephyr 7 aircraft had a wing span of 70 ft (22.5 m).
The Zephyr 8 aircraft is larger, with increased payload capacity, and will employ custom Li-S battery packs designed and assembled in Tucson Arizona. The Zephyr aircraft is at the forefront of the HAPS arena, holding 3 world records.
Zephyr aircraft have already flown in a number of different airspaces under challenging winter conditions. Airbus Defence and Space has obtained permissions to fly these aircraft in both commercial and military situations alike. No other HAPS system has as many flight hours, reliability and flexibility of operation.
About Sion’s battery pack
The battery packs utilize Sion’s unique, high specific energy Li-S technology and provide 350 Wh/kg, the highest available for a rechargeable battery.
* The company website indicates the possibility of 600 Wh/kg in the near future, but we saw this statement in the past and would like to see some progress, like at least 400 Wh/kg.
The Li-S battery packs are engineered to minimize total pack weight. Advanced electronic controls maintain battery conditions throughout the flights.
A fertile cooperation
Both companies are pleased to work with each other and hope that such cooperation will lead to mutual benefitting.
“We are extremely pleased and honored to collaborate with Airbus on advancing its strategically important HAPS program while building on the Airbus/Sion Power relationship established several years ago. Our experience working together has gained important momentum as Airbus Defence and Space program continues to lead the industry supplying advanced HAPS aircraft.”
“We are excited to be working with Airbus on this transformational program.”
“Our collaboration with Sion Power will enhance Airbus Unmanned Aerial Pseudo-Satellite vehicles important to our extensive portfolio of aircraft products. Sion Power is a world leader in light weight, high energy Li-S battery technology. Combining Airbus and Sion Power engineering expertise has proven to be a successful platform for our on-going success.”
Well, as far as we can see, expectations are quite high. Let’s wish them good luck and wait for more news from them.
If everything will go smoothly and this technology matures into 600 Wh/kg lasting pack, it might change the entire automotive industry.
