On the evening of March 31, Fal Sheng had issued a risk-warning announcement stating that the fluctuation range of the company’s stock price has seriously deviated from the company’s fundamentals. There is a risk of overheating market sentiment and irrational speculation. If the company’s stock price rises further, the company may apply to the Shenzhen Stock Exchange for a suspension to examine the matter. Investors participating in trading may face significant risks.

China’s sodium-ion batteries achieve a major breakthrough, completely cutting off thermal runaway

According to Science and Technology Daily, on April 6, the Hu Yongsheng team from the Institute of Physics of the Chinese Academy of Sciences published a major breakthrough in 《Nature·Energy》. The team successfully developed a polymerizable non-flammable electrolyte (PNE) with a self-protective function. For the first time in the anode-level sodium-ion batteries globally, they achieved a complete prevention of thermal runaway.

The team broke from the traditional understanding that “flame-retardant electrolytes equal safety.” Instead of relying on a single line of defense, they built a “three-in-one” intelligent safety protection system: thermal stability—interfacial stability—physical isolation. When the battery temperature rises abnormally to above 150°C, the PNE automatically solidifies from liquid into a dense barrier, like an “intelligent fire wall” built inside the battery, completely cutting off the propagation path of thermal runaway.

Notably, this breakthrough does not sacrifice the battery’s high performance. The battery combines excellent wide-temperature performance (-40°C to 60°C) and high-voltage stability (>4.3V). Moreover, the materials are mature industrialized products, giving the battery significant advantages in industrialization competitiveness.

This achievement updates people’s understanding of battery safety. In the future, it will be applied to the anode-level sodium-ion battery products of CeraHai Sodium Technology Co., Ltd., laying a solid foundation for the commercialization rollout of sodium-ion batteries in areas such as electric vehicles, heavy-duty trucks, and large-scale energy storage.

Sodium battery commercialization accelerates

Against the backdrop of ongoing deepening of energy transition, sodium-ion batteries—thanks to their wide operating temperature range, resource security, and potential for economic advantage—are becoming an important component of diversified energy solutions.

The core advantages of sodium batteries first show up on the resource side. Lithium’s content in the earth’s crust is only 0.006%, and 70% is concentrated in South America’s “lithium triangle.” By contrast, sodium’s content in the earth’s crust is as high as 2.75%, more than 400 times that of lithium. Sodium is abundant in seawater and table salt. In addition, China’s self-sufficiency rate for sodium salts is close to 100%, so there is no need to rely on imports, effectively avoiding geopolitical risks and price fluctuations associated with lithium resources.

In terms of cost, after long-term process optimization and the formation of economies of scale, sodium batteries’ cost advantages are expected to become even more pronounced. Industry estimates suggest that once the industry chain reaches scaled maturity, the total cost of sodium batteries is expected to be 30% to 40% lower than that of lithium batteries.

Entering 2026, good commercial news for sodium-ion batteries in the power battery sector has continued to emerge. In January, CATL released its first mass-produced sodium-ion battery for light commercial vehicles. In February, the world’s first mass-produced sodium-electric passenger vehicle made its debut and is planned to be listed this year. On March 30, BoNa New Energy’s RMB 620 million first-phase annual production project of 2GWh sodium-ion batteries was completed and began operations in Harbin.

On March 31, at the 2026 Global Sodium-ion Industry Ecosystem Conference hosted by CeraHai Sodium, the company’s general manager Li Shujun said that after 2028, the performance market will drive sodium-ion batteries to reach a 100GWh+ industrial scale. The cell cost will fall to 0.3 yuan/Wh, and technological evolution will increase the energy density of energy-type sodium-ion battery products to over 180Wh/kg.

Earnings updates for 25 concept stocks

According to Securities Times · Data Orchard statistics, regarding secondary-market performance, as of the close on April 3, the average decline of sodium-battery concept stocks year-to-date was 1.03%.
