Jakarta, INTI – Researchers from China have achieved a major breakthrough in lithium battery technology with high energy density, capable of operating in ultra-low-temperature environments. This innovation has proven successful in a drone flight test conducted in China's northernmost city, where temperatures reached minus 36 degrees Celsius.
This achievement opens new opportunities for exploration in low-temperature regions, such as polar expeditions, border patrols, disaster rescue operations, and logistics in extreme environments. The testing was conducted by a team from the Dalian Institute of Chemical Physics (DICP), under the Chinese Academy of Sciences (CAS), as reported by Science and Technology on Sunday, March 16, 2025
Successful Flight Test: Stability and Optimal Performance
The battery developed by the DICP team demonstrated outstanding performance during testing. The hexacopter drone used in this experiment was able to hover stably, follow complex navigation routes, and maintain voltage without experiencing sudden power loss.
"This successful test marks a new breakthrough in high-performance drone power battery technology," said Chen Zhongwei, the lead researcher from DICP. Chen added that the drone could achieve a quick startup and navigate extreme environments without obstacles, reinforcing the battery's reliability in low-temperature conditions.
Technological Innovation: The Key to Durability in Extreme Temperatures
One of the biggest challenges in developing lithium batteries for low-temperature environments is the drastic performance drop caused by extreme cold. To address this, the research team utilized an innovative electrolyte formulation and modified anode materials, enabling the battery to deliver stable power output within a temperature range of minus 40 to 50 degrees Celsius.
Additionally, the implementation of adaptive thermal management technology and low-temperature impedance optimization has reduced the battery capacity degradation to less than 10 percent at minus 40 degrees Celsius. This figure is significantly better than the industry standard, which typically experiences a 30-50 percent decline under similar conditions.
"This breakthrough significantly extends the mission duration for drones operating in polar or high-altitude regions, minimizing the need for frequent recharging," explained Chen.
Next Steps: Expanding Applications
With this achievement, the research team plans to continue refining the battery technology to expand its applications, including various equipment operating in extreme environments.
"We will continue enhancing the battery’s capabilities to broaden its applications in extreme environmental conditions," added Chen.
This success marks a significant advancement in battery technology, opening new opportunities for exploration and operations in low-temperature environments that were previously challenging.
Conclusion
This breakthrough in lithium battery technology represents a major step forward in the drone industry and equipment operating in extreme conditions. With superior durability and stability compared to industry standards, this innovation can support crucial operations such as polar exploration, rescue missions, and logistics in difficult terrains. Moving forward, further developments will unlock broader applications across various sectors that require reliable power solutions in extreme environments.
