The Fulin Sodium-ion Battery Energy Storage Station entered operation on May 11 in Nanning, the capital of the Guangxi Zhuang autonomous region in southern China. Its initial storage...
In two years, China will have nearly 95 percent of the world''s capacity to make sodium batteries. Lithium battery production will still dwarf sodium battery output at that point,...
China is leading the way in battery innovation, particularly with its advancements in sodium-ion batteries. As a pivotal player in the global energy storage landscape, China''s strategic focus on sodium-ion technology is yielding significant benefits.
BYD started constructing its first sodium-ion battery plant in Xuzhou, a city about halfway between Beijing and Shanghai. The investment into the project is 10 billion yuan (USD 1.4 billion), and the planned annual output capacity is 30 GWh.
The first generation had an energy density of 160 Wh/kg, while the next one is expected to exceed 200 Wh/kg. Mass production of the new product is not expected before 2027. China switches on first large-scale sodium-ion battery China Southern Power Grid has deployed a 10 MWh sodium-ion battery in China''s Guangxi Zhuang region. It is the
The state utility says the 10 MWh sodium-ion battery energy storage station uses 210 Ah sodium-ion battery cells that charge to 90% in a mindblowing 12 minutes. The system comprises 22,000 cells.
Once the project reaches 100 MWh, it could release 73,000 MWh of clean energy each year. That''s enough to power 35,000 households and reduce carbon dioxide emissions by 50,000 tonnes annually.
In an interview with China Central Television, Gao Like, a manager at the Guangxi branch of China Southern Power Grid, said that the energy conversion efficiency of its sodium-ion battery energy storage system exceeds 92%. It''s comparable to the efficiency of common lithium-ion battery storage systems, at 85-95%.
Chen Man, a senior engineer at China Southern Power Grid, said [via the South China Morning Post] that once sodium-ion battery energy storage enters the stage of large-scale development, its cost can be reduced by 20-30%. He continued:
This can be achieved through further improvements in the sodium-ion battery structure, manufacturing process, material utilization, and cycle life, thus lowering the energy storage cost per kilowatt-hour of electricity.
Large-scale sodium-ion batteries are gaining momentum due to their lower cost and abundance of raw materials compared to lithium-ion batteries. The challenges with sodium-ion batteries have been lower energy density and shorter lifespans that can limit efficiency and long-term performance in large-scale applications.

China is leading the way in battery innovation, particularly with its advancements in sodium-ion batteries. As a pivotal player in the global energy storage landscape, China''s strategic focus on sodium-ion technology is yielding significant benefits. Sodium-ion batteries are emerging as a game-changer in the energy sector, and China''s rapid deployment highlights this development.
China has made remarkable strides in deploying sodium-ion batteries at a large scale. One notable project is the 10 MWh Sodium-ion Battery energy storage station by China Southern Power Grid in the Guangxi Zhuang region. This initiative is just a part of a broader 100 MWh project in the area. Similarly, Sineng Energy has connected the first phase of a massive 100MW/200MWh Sodium-ion Battery storage project to the grid. These large-scale deployments demonstrate the potential of sodium-ion technology for effective energy storage solutions.
China has identified sodium-ion technology as a crucial step towards energy independence. With vast reserves of sodium, China can reduce its dependence on imported lithium. Major companies like BYD are at the forefront of this endeavor, with strong government backing. BYD has constructed the world’s first mass-production facility dedicated to sodium-ion batteries, targeting an annual production capacity of 20GWh by 2025. These batteries promise similar range capabilities to Lithium-ion batteries but offer quicker charging times and higher energy densities.
The introduction of sodium-ion batteries is poised to transform global battery supply chains. With competitive advantages in cost and availability, these batteries offer new opportunities for energy storage solutions worldwide. China’s progress in Sodium-ion Battery technology signifies a critical moment in energy history, positioning the nation as a global leader in battery production. This advancement is not only reshaping the industry but also redefining global dynamics in the energy sector.
Beyond China, the global community is also investing heavily in Sodium-ion Battery research. The U.S. Department of Energy''s ARPA-E program is funding companies like 24M Technologies to develop sodium-ion batteries for Electric Vehicles. The Argonne National Laboratory leverages its expertise with Lithium-ion batteries to explore roadworthy sodium-ion solutions, utilizing the chemical kinship between sodium and lithium. These efforts highlight the worldwide interest in advancing sodium-ion technology.
In conclusion, China’s strategic initiatives, coupled with its substantial sodium resources, are positioning it as a leader in Sodium-ion Battery development. This represents a key pivot in sustainable energy storage, with the potential to impact global energy strategies significantly.
