Sion Power To Supply Airbus DS With 350 Wh/kg Li-S Batteries
Airbus Defense and Space continues to use 350 Wh/kg energy dense lithium sulfur (Li-S) batteries supplied from Sion Power in its new project.
They are developing a successor for Zephyr 7, the High Altitude Pseudo-Satellite (HAPS) aircraft, which can stay in the air many days.
In the press release, Sion Power is still stating 350 Wh/kg as the highest value for rechargeable batteries. 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.
If this technology matures and will enable for high power, long lasting pack, it could change the automotive industry.
“This 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. 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.”
John Kopera, Sion Power’s Vice President, Commercial Operations said:
“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.”
Dr. Dennis Mangino, Sion Power CEO, added:
“We are excited to be working with Airbus on this transformational program.”
Thomas Keupp, Vice President and Head of Portfolio Management at Airbus, stated:
“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.”
