With the rapid development of electric vehicles, energy storage stations, and smart devices, lithium-ion batteries have become the core energy carriers of modern technology. However, as application scenarios expand, the low-temperature shortcomings of lithium-ion batteries are becoming increasingly apparent. When temperatures drop below zero, traditional lithium-ion batteries often suffer from sharp capacity loss, charging difficulties, and reduced discharge efficiency—commonly referred to as “low-temperature shock.” These issues seriously restrict their applications in extremely cold environments. How to maintain efficiency, stability, and safety at sub-zero temperatures has become a critical industry challenge.
As an innovation pioneer in energy technology, UltraXel has successfully overcome this global challenge through its self-developed ultra-low-temperature lithium-ion battery technology, providing reliable power solutions for electric vehicles, drones, energy storage stations, and polar exploration equipment.

Industry Pain Point: The Low-Temperature Bottleneck of Lithium-Ion Batteries
The performance degradation of conventional lithium-ion batteries in low-temperature environments is a complex and multi-factor issue. When operating temperature drops from 77°F to -4°F(25℃ to -20℃), the capacity retention of ordinary lithium-ion batteries is often less than 50%, charging time extends by 2–3 times, and discharge power decreases by more than 60%. This decline is mainly caused by the following factors:
Electrolyte Viscosity Increase and Ion Transport Blockage At low temperatures, the viscosity of carbonate-based electrolytes rises sharply, significantly slowing lithium-ion mobility. When the temperature falls below -4°F(-20 ℃), ionic conductivity is reduced to just one-fifth of normal levels, severely hindering charge transfer.
Electrode Kinetics Deterioration The electrochemical reaction rate of electrode materials decreases exponentially with temperature. Graphite anodes, in particular, face greater resistance to lithium-ion intercalation at low temperatures, increasing the risk of lithium dendrite formation, which not only shortens battery life but also poses safety hazards.
Increased Interfacial Resistance and Polarization The solid electrolyte interphase (SEI) exhibits sharply higher resistance at low temperatures. The higher activation energy required for lithium-ion transfer leads to significant polarization and rapid discharge performance decline.
These limitations create a series of real-world challenges:
Electric vehicles suffer drastic range loss in cold regions;
Drones experience sharply reduced flight time or fail to operate in low temperatures;
Grid energy storage systems operate inefficiently in winter, with unstable output.
At this critical stage of global energy transformation, the industry urgently needs a lithium-ion battery with wide-temperature adaptability.
