Location: Taxkorgan, Xinjiang, 3,600 m above sea level
Ambient temperature: -10°C to 0°C
Atmospheric pressure: 85-90 kPa
Application equipment: a wireless intercom, a bionic bird UAV, and an intelligent launch system.
Portable Power Supply:
A 300 Wh portable power supply using Li-S batteries weighs less than 900 g; a lithium-ion battery of equivalent energy weighs about 2.15 kg—a 60% weight reduction. Application verification was completed and received unanimous praise.
Driving Reconnaissance-Strike UAV Significantly Improves Aircraft Endurance
In December 2021, Li-S power batteries drove a 10 kg-class fixed-wing reconnaissance-strike UAV to achieve 95 minutes of loitering flight time—2 to 3 times that of a lithium-ion battery of equivalent weight. Li-S battery technology provides longer endurance for UAV operations in air-ground reconnaissance, water resources, coal, and petroleum fields.
Drives Tethered UAV to First Place in Qinghai-Tibet Plateau Bidding Comparison Test
Near-Space Solar UAV Energy Storage Battery
Compared with NMC lithium-ion battery packs of the same weight, the Li-S battery pack increases the battery endurance capacity by 50%, laying a technical foundation for day-and-night flight of near-space solar UAVs.
A 5,000 m flight platform equipped with Li-S battery packs performed excellently in key technical indicators such as endurance, maximum discharge power, and average power, extending UAV operating time by about 2 hours 40 minutes.
