At the recently concluded Smart Energy Week in Japan, the UltraXel team proudly presented our wide-temperature lithium battery solutions designed for extreme environments. From freezing -40°C to scorching +85°C, our advanced battery technologies deliver consistent performance, safety, and durability where traditional batteries cannot.

The event offered a valuable opportunity to connect with international customers and partners, and we were truly impressed by the rising demand for wide temperature batteries across multiple industries. In particular, sectors such as robots, AGVs (Automated Guided Vehicles), and underwater flashlights are increasingly seeking heat resistant batteries, cold resistant batteries, and outdoor batteries capable of operating reliably under extreme conditions.

Throughout the exhibition, we also discovered a growing interest in energy solutions for applications including T-Box power supply, E-Call batteries, BBU batteries, GPS tracker batteries, cold chain batteries, outdoor security camera batteries, seismic monitoring batteries, logging tool batteries, and defense batteries. These markets share a common challenge: ensuring stable and safe energy in both high-temperature and ultra-low-temperature environments.

UltraXel’s wide temperature lithium battery technology is designed precisely to address these challenges. Whether in desert heat, arctic cold, deep-sea environments, or outdoor industrial conditions, our solutions enable critical systems to perform reliably where power matters most.


Thank you, Japan! The Smart Energy Week exhibition allowed us to not only showcase our latest innovations but also explore exciting opportunities for future collaborations. We look forward to working with global partners to accelerate the adoption of wide-temperature battery solutions for extreme environments. We’ll see you very soon!
