“Still Running at 29,000 Feet”: This Lithium Battery Survived -40°F for Days Without a Single Drop in Power

In recent years, the demand for reliable power solutions in extreme environments has grown significantly. As researchers and explorers venture into more remote and challenging terrains, the need for power systems that can withstand harsh conditions becomes paramount. A remarkable breakthrough has emerged from China, where Wiltson Energy has developed an advanced low-temperature lithium battery. This battery has proven its mettle on Mount Everest, powering scientific equipment for an impressive 12 days without interruption. This achievement highlights the potential of this technology to revolutionize power solutions in extreme environments.

Revolutionizing Cold Climate Solutions

Powering equipment in extremely cold environments has always posed significant challenges. Traditional lithium-ion batteries, such as ternary lithium and lithium iron phosphate (LFP), tend to falter in low temperatures. They often require additional heating elements to prevent freezing or failure, leading to increased complexity and energy consumption. Wiltson Energy has tackled this issue head-on by advancing the chemistry of low-temperature lithium iron phosphate (LiFePO₄) and integrating it into a robust battery module.

This innovative battery system was crucial during the Mount Everest mission, supporting the world’s highest automatic weather station and a critical ice core drilling unit. One of the most notable achievements was its ability to maintain over 80 percent discharge efficiency at -40°F, nearly matching its performance at room temperature. This ensured that essential scientific instruments operated without power loss, even at the summit of the mountain.

The battery’s capability to directly charge via solar power at 32°F further distinguished it from traditional systems. By eliminating the need for external heating systems, Wiltson’s battery reduces system complexity and energy consumption. Additionally, its durable cylindrical steel case minimizes the risk of pressure-related failures, ensuring stable and reliable performance in extreme conditions.

Monumental Achievement on Everest

Robert Xie, Wiltson’s chairman and CTO, described the successful powering of scientific equipment on Mount Everest as a monumental achievement. The mission showcased the unmatched reliability and performance of Wiltson’s low-temperature battery technology in one of the world’s most demanding environments. Xie emphasized that the battery’s ability to function without external heating systems simplifies energy infrastructure in remote and extreme settings, enhancing efficiency and ensuring long-term reliability for mission-critical operations.
