Imagine operating a drone in some of the coldest climates on Earth without worrying about the battery losing power. That’s exactly what a team at the Dalian Institute of Chemical Physics (DICP) has achieved. Backed by the Chinese Academy of Sciences, these researchers have developed a lithium battery that thrives in ultra-low temperatures, and they’ve put it to the test in the chilly conditions of Mohe City.
Reported by Science and Technology Daily, this innovative battery can power a UAV even when temperatures plummet to -32.8°F (-36°C). This opens up exciting new possibilities for aerial operations in freezing environments, from polar research to border monitoring and emergency rescues.
Cold weather usually spells trouble for batteries. They tend to lose power quickly due to increased electrolyte viscosity and sluggish ion transport. But the DICP team has cracked the code, ensuring UAVs can fly steadily and even perform complex maneuvers in harsh conditions.
Under the guidance of Chen Zhongwei, the team fine-tuned the electrolyte and revamped the anode materials. The result? A battery that works from -40°F to 122°F (-40°C to 50°C) without the pesky issue of lithium plating, which often shortens battery life and compromises safety.
Field tests have been promising, showing that the battery holds over 90% of its capacity after enduring extreme cold. This makes it one of the most adaptable options for UAVs and other demanding environments.
With less than a 10% energy loss at -40°F, compared to the usual 30-50%, this battery means fewer recharges for UAVs on icy missions. DICP is now focusing on scaling up production and teaming up with aerospace and defense sectors to add even more thermal management features.
Chen shared their vision, saying, “Our goal is to push the boundaries of lithium battery technology to ensure reliable energy solutions for the most demanding environments.” This breakthrough could redefine what’s possible for battery-powered devices in extreme climates.
