China’s sodium-ion batteries achieve major breakthrough

Completely block thermal runaway

According to a report by the Science and Technology Daily, on April 6, a team led by Hu Yongsheng from the Institute of Physics, Chinese Academy of Sciences, published a major achievement in Nature Energy: the team successfully developed a polymerizable nonflammable electrolyte (PNE) with self-protection functionality. For the first time in the world, it achieves a complete blockage of thermal runaway in ampere-hour-class sodium-ion batteries.

The team broke the traditional understanding that “flame-retardant electrolytes equal safety,” moved beyond a single line of defense, and built an intelligent safety protection system with a “three-in-one” design: thermal stability, interfacial stability, and physical isolation. When the battery temperature rises abnormally to above 150°C, the PNE automatically solidifies from liquid into a dense barrier—like building an “intelligent firewalls” inside the battery—to completely cut off the transmission path of thermal runaway.

值得一提的是，这一突破并未牺牲电池的高性能表现。The battery combines excellent wide-temperature performance (-40°C to 60°C) and high-voltage stability (>4.3V), and the materials are all mature industrialized products, with strong advantages in industrialization competitiveness.

This achievement has refreshed people’s understanding of battery safety. In the future, it will be applied in ampere-hour-class sodium-ion battery products of Zhongke Hainao Technology Co., Ltd., laying a solid foundation for the commercialization and implementation of sodium-ion batteries in areas such as electric vehicles, heavy trucks, and large-scale energy storage.

Commercial adoption of sodium batteries speeds up

Against the backdrop of ongoing deepening of the energy transition, sodium-ion batteries, with their wide operating temperature range performance, resource security, and economic potential, are becoming an important part of diversified energy solutions.

The core advantages of sodium batteries first show in the resource end. Lithium’s abundance in the Earth’s crust is only 0.006%, and 70% is concentrated in South America’s “Lithium Triangle”; whereas sodium’s abundance in the Earth’s crust reaches 2.75%, more than 400 times that of lithium. Sodium is abundant in seawater and table salt. Moreover, China’s sodium salt self-sufficiency rate is close to 100%, meaning it does not rely on imports, which can effectively avoid geopolitical risks related to lithium resources and the impact of price fluctuations.

From a cost perspective, after long-term process optimization and the formation of economies of scale, sodium batteries’ cost advantage will further stand out. Industry estimates suggest that once the supply chain scales up and matures, the overall cost of sodium batteries is expected to be 30% to 40% lower than that of lithium batteries.

Entering 2026, there are ongoing good news stories for commercial deployment of sodium-ion batteries in the power battery sector: in January, CATL released its first mass-produced sodium-ion batteries for light commercial vehicles; in February, the world’s first mass-produced sodium-ion passenger car made its debut and is planned to be上市 this year; and on March 30, BoNuo New Energy’s 2GWh phase-one annual sodium-ion battery project with an investment of 620 million yuan was completed and began production in Harbin.

On March 31, at the 2026 Global Sodium-ion Industry Ecology Conference hosted by Zhongke Hainao, the general manager of Zhongke Hainao, Li Shujun, said that it is expected that after 2028, the performance market will drive sodium-ion batteries to reach a 100GWh industrial scale, cell costs will be reduced to 0.3 yuan/Wh, and technological evolution will increase the energy density of energy-type sodium-ion battery products to above 180Wh/kg.

25 concept stocks report good earnings

According to statistics from Securities Times·Data Treasure, in terms of secondary market performance, as of the close on April 3, the average decline of sodium battery concept stocks since the start of the year was 1.03%. Of these, 6 stocks bucked the trend and rose by more than 10%, namely Baichuan Shares (百川股份), Minmetals Xineng (五矿新能), Weike Technology (维科技术), EVE Energy Technology (派能科技), T&K Technology (传艺科技), Huabao Xineng (华宝新能).

Baichuan Shares has accumulated a gain of 78.94% year-to-date, ranking first. The company’s subsidiary, Haiji New Energy (海基新能源), has made technical reserves and conducted related R&D for sodium-ion batteries, and has released finished products, but currently has not entered mass production.

Minmetals Xineng has gained 37.52% in total, ranking second. The company’s ultra-low-cost poly-anion sodium-ion cathode has entered the phase of pilot trial production at the hundred-kilogram scale.

Weike Technology has gained 30% in total, ranking third. The company began researching sodium batteries in 2019, has mastered key technologies related to material formula systems and production process conditions, and has established an engineering research center for sodium batteries. The sodium batteries developed by the company already have an energy density of above 160Wh/kg, and the cycle life can reach more than 6,000 cycles.

According to Data Treasure statistics, regarding performance data, based on annual reports, earnings bulletins, and the lower bound of forecast net profit (if there is no lower bound, the announced value is used), there are 25 sodium battery concept stocks with year-over-year growth in net profit (including turning from loss to profit) in 2025. Among them, 8 stocks turned from loss to profit, including Minmetals Xineng, Tianyuan Shares (天原股份), Shanshan Shares (杉杉股份), Dofull (多氟多), EVE Energy (鹏辉能源), and Chanyi Technology (传艺科技), etc.

EVE Energy expects 2025 net profit to be 170 million yuan to 230 million yuan, turning from loss to profit year over year. During the reporting period, the company’s products saw strong production and sales, sales orders increased, and operating revenue grew. The company initiated research on sodium batteries in 2021 and adopted a two-technology-route R&D strategy: poly-anion and layered oxide. At the same time, the company is among the first batch of entities nationwide to pass sodium-ion battery evaluation and in 2023 achieved first-generation commercial delivery, with products used in energy storage power station projects.
