A research team at Tsinghua Shenzhen International Graduate School (Tsinghua SIGS) has developed a new approach to significantly boost the energy density of lithium-sulfur batteries, potentially enabling drones and other low-altitude aircraft to achieve much longer flight times on a single charge. Their findings were published on May 6, 2026, inNatureunder the title Molecular skeleton programming of premediators in sulfur electrochemistry.Most conventional drones currently rely on lithium-ion ba
