As the global thrust toward sustainable energy solutions gathers pace, the quest for advanced, eco-friendly energy storage options has surged to the forefront of technological innovation. Arohora Energy Technology Co. Ltd. (Arohora) is meeting the surge in demand with its game-changing sodium salt batteries. Renowned for its exceptional safety and eco-friendly design, these batteries have received widespread acclaim for achieving zero ambient emissions and being free from highly toxic materials throughout the supply chain.
Each sodium salt battery developed by Arohora embodies a leap in energy storage technology, delivering a theoretical specific energy of 790 Wh/kg. More than just numbers, the real-world application of these batteries reveals an impressive capacity range of 135 to 200 Wh/kg at the cell level and 220 Wh/L for the battery packs. These batteries stand out for their high energy density and exceptionally low internal resistance, which enables them to endure overcharging and deep discharge cycles without any loss in performance. The sodium salt batteries shine with a 100 percent coulombic efficiency and a remarkable lifespan—exceeding 15 years with a cycle life of over 4,500 at 80 percent depth of discharge.
Arohora’s commitment to sustainability is integral to its design philosophy. The company reduces environmental impact upon disposal by using 100 percent recyclable materials that eliminate the need for high-temperature melting.
The batteries’ fully sealed structure is engineered to resist external temperature fluctuations, which enhances their durability and operational reliability.
“Our batteries are designed with safety as a core principle from the start,” explains Yongmin Zhu, CEO of Arohora. “While other batteries prioritize functionality first and then enhance safety, our approach ensures safety from the beginning without compromising performance.”
This safety-first approach is tested under the most demanding conditions, proving Arohora’s batteries ideal for critical uses, from uninterruptible power supplies (UPS) and backup power to large-scale energy storage systems (ESS).
Looking ahead, Arohora is on the brink of launching the world’s first 720V high-voltage sodium salt battery designed for grid-scale energy storage. The production line for this groundbreaking product is nearing completion, with final installation and debugging underway. Once operational, it will have a production capacity of 500 MW—the largest globally—and state-of-the-art automation and integration capabilities.
A Game-Changing Approach to Cost and Efficiency
The name “Arohora” reflects the company’s versatile capabilities and exceptional qualities, blending elements from “aurora,” “Sahara,” and “aloha” to signify the remarkable performance of its energy storage products across diverse environments, from extreme cold and heat to humid island conditions. This versatility is visually represented in the firm’s logo, featuring three warm-colored circles—orange, yellow, and white. It symbolizes the high-temperature operation of solid batteries and the company’s multidimensional development path—one generation of production, one of reservation, and one of R&D.
Yongmin emphasizes, “No one type of battery can be used in all working scenarios. Our sodium salt batteries cover areas other batteries cannot, providing our customers with a safe, reliable, and versatile energy solution.” This commitment to safety was notably showcased on July 10th, 2024, when Arohora’s batteries withstood gunfire from a 12.7mm heavy machine gun at 50 meters during a controlled safety test, demonstrating exceptional resilience with no penetration, smoke, or fire.
Arohora’s commitment to safety is further emphasized through its rigorous quality management program, which involves proactive risk identification and thorough independent examinations conducted by both the Experiment and Test Center and the Quality Department. In addition, Arohora’s focus on cost-effectiveness is a standout feature. By maintaining the entire supply chain within China—from sourcing materials to production and management systems—Arohora has significantly cut costs. The company has achieved a milestone by reducing the cost of sodium batteries to 50 percent less than their lithium counterparts, and it sees potential for even greater cost efficiencies in the future.
The company believes there is room for optimization as it continues refining its batteries. Arohora’s dedication to continuous innovation and technological advancements is illustrated through its various pilot projects.
For instance, in February 2024, Arohora partnered with China Unicom on a project in Genhe, Inner Mongolia—often referred to as the cold pole of China, where temperatures average between -33°C and -37°C from December to February. The collaboration successfully demonstrated the stability and reliability of Arohora’s batteries in extreme cold, ensuring consistent performance even when temperatures plunge well below -20°C. Another upcoming pilot in Tulufan, Xinjiang—China’s hottest region—will further test these batteries in temperatures reaching 40°C, highlighting their robustness in severe climates.
Similarly, Arohora is engaged with the State Grid Corporation of China to complete another significant pilot project. Here, Arohora’s sodium salt batteries undergo rigorous testing across various grid applications. These trials are crucial for demonstrating the batteries’ performance and reliability, ultimately paving the way for their broader adoption across multiple industries.
Experts Fueling Next-Gen Energy Innovations
To stay at the cutting edge of technological advancements in energy storage, Arohora collaborates with top research institutions like the Chinese Academy of Sciences (CAS) and its affiliated institutes. Globally, it maintains an ongoing dialogue with the Fraunhofer Institute in Germany, a leading center for scientific research.
“Continuous cooperation with top research institutions allows us to stay innovative and develop cutting-edge solutions. These collaborations are vital for our long-term success and for meeting the unique needs of our customers,” explains Yongmin.
Beyond these collaborative research efforts, Arohora finances targeted research and development (R&D) projects tailored to specific customer requirements. This customer-centric approach enables the rapid deployment of new technologies, with Arohora often sharing patents with clients to accelerate their implementation.
A notable example is Arohora’s collaboration with a leading automotive manufacturer to develop sodium salt batteries for electric buses intended to operate in extreme weather conditions. The partnership has not only led to the creation of a new battery prototype. However, it has also resulted in several joint patents, highlighting Arohora’s ability to advance battery technology through collaborative innovation.
Arohora’s technological R&D and core team are driven by experts from prestigious Chinese universities, research institutions, and renowned enterprises such as China Aerospace Science and Technology Corporation, Aviation Industry Corporation of China Ltd., and Bosch. Their collective expertise ensures that Arohora can effectively translate scientific research into practical, high-quality energy storage solutions.
The team has enabled Arohora to establish China’s only production line for sodium salt batteries with completely independent intellectual property rights.
