Sion Power Corporation has signed a three-year agreement to supply its proprietary lithium-sulfur batteries for use in Airbus Defence and Spaceâ€™s Zephyr High Altitude Pseudo-Satellite (HAPS) aircraft.
The HAPS is an aircraft that stays aloft for long periods of time, allowing it to perform many of the functions of a satellite, but more flexibly and cheaply. One of the challenges is supplying constant power, which is where the need for advanced batteries comes in.
Sionâ€™s batteries were successfully used in Airbusâ€™s Zephyr 7, which achieved record-breaking flights of more than 14 days. The Zephyr 8 aircraft is larger, with increased payload capacity. Sionâ€™s custom Li-S battery packs provide specific energy of 350 Wh/kg, which the company claims is the highest available for a rechargeable battery.
â€œSion Power is a world leader in lightweight, high-energy Li-S battery technology,â€ said Airbus VP Thomas Keupp. â€œCombining Airbus and Sion Power engineering expertise has proven to be a successful platform for our ongoing success.â€
