A sodium-ion Battery project has been launched in Qingdao North Coast Data Center (QNCDC), making it the first application of its kind in big data centers. The project aims to improve energy efficiency and support the development of green data center infrastructure.

Green Power, the technology provider, has been working on sodium-ion technology for three years. It is described as a combination of layered oxide and polyanion systems, which has resulted in multiple technological innovations and breakthroughs. The polyanion system has achieved a highly stable configuration with increased energy density and a longer battery life of over 6000 cycles. Meanwhile, the layered oxide system has developed a high-voltage system with an energy density of 150Wh/kg and a cycle life of up to 3000 cycles.

Aside from reducing energy costs, the sodium-ion battery project will also contribute to ancillary services that improve the reliability and stability of the power grid. Sodium-ion battery technology is considered one of the most commercially advanced non-lithium battery technologies. It is expected that the global annual production capacity will reach around 1GWh this year and rise to 5-10GWh by 2025.

Previously, the world’s first sodium-ion gigafactory was opened in China by China Three Gorges Corporation in December 2022. The sodium-ion battery space continues to see significant advancements, including fundraising efforts by Altris in Sweden, the establishment of a 100MWh sodium solid-state battery factory in Germany, and investments in technology provider Natron Energy by United Airlines.
