China, a land of innovation, is set to mark a decisive turning point in the field of batteries with the launch of a colossal centre dedicated to sodium-ion cells. This technology, promised a bright future, could well transform the global energy landscape by 2026.
An ambitious project
Many believe that 2026 will be the pivotal year for sodium-ion batteries. This type of technology, which could rival traditional lithium-ion batteries, is already the subject of palpable excitement. In China, Eve Energy, a major player in battery manufacturing, has recently announced the construction of a centre dedicated to the research and development of these cells. This site will not be limited to theoretical studies: it will also commence mass production of these revolutionary accumulators.
Located near the company’s headquarters in Huizou, this centre is expected to achieve a production capacity of 2 GWh per year by the end of 2026. An ambition that reflects Eve Energy’s desire to propel this technology to unexplored heights by developing manufacturing processes suited for large volumes.
A large integrated centre
Eve Energy is not just building a simple factory; it plans to integrate all stages of production and research on-site. The complex will also include a space dedicated to artificial intelligence and robotics, essential tools for optimising manufacturing. With an impressive area of 50,000 square metres, this campus is set to become “the main Chinese hub for the industrialisation of sodium batteries and the integration of artificial intelligence and robotics“, as the company proudly states.
By November 2025, Eve Energy has established itself among the industry leaders, ranking fifth among battery manufacturers in China and ninth globally. With an installed capacity of 3.59 GWh and a market share of 3.84%, the company is well-positioned to capitalise on this new technology.
A growing sector
Eve Energy is not alone in this frantic race towards the future of batteries. Other industry giants, such as CATL, are also interested in sodium-ion cells. Their Naxtra model, for example, uses this technology to offer an energy density of 175 Wh/kg, thus competing with the performance of lithium iron phosphate batteries.
BYD, for its part, positions itself as a key player in the field. Currently the second-largest producer globally behind CATL and Eve Energy, the Shenzhen-based company has recently begun construction of a Gigafactory. Set to produce up to 30 GWh per year from 2024, this factory is expected to reach its full capacity in the coming years. An ambition that reflects the current dynamics of the sodium-ion battery market.
These companies are not only putting pressure on their competitors, but they are also paving the way for an energy revolution. Research on sodium-ion batteries could potentially reduce costs while offering competitive performance. A real boost for the automotive industry and renewable energies.
