To advance China’s dual-carbon goals and accelerate the energy transition, the 2023 Guiding Opinions of the Ministry of Industry and Information Technology and Other Five Departments on Promoting the Development of the Energy Electronics Industry (No. 181 [2022] of the Ministry of Industry and Information Technology), called for intensified efforts in industrializing new energy storage battery technologies, scaling up advanced energy storage products, and accelerating the development of emerging technologies such as sodium-ion batteries—along with corresponding standardization efforts.

To further strengthen new growth engines through integration of next-generation information technology and new energy and deepen supply-side structural reform of new energy storage, eight government departments including the Ministry of Industry and Information Technology (MIIT) and the National Development and Reform Commission released the Action Plan for Promoting High-Quality Development of the New-type Energy Storage Manufacturing Industry (No. 7 [2025] of the Ministry of Industry and Information Technology) in February 2025. The plan outlines efforts to optimize the industrial system, cultivate 3–5 ecosystem-leading enterprises, enhance product performance, expand application fields, and guide the industry toward high-end, intelligent, and green development. Sodium-ion batteries are a key focus area under the “New-Type Energy Storage Products and Technology” category of the action plan, highlighting the development of anode materials including high-performance hard carbon, and sieved carbon, and high-capacity cathode materials, as well as breakthroughs in system integration and application technologies for large-scale sodium battery energy storage systems.

The 4th Sodium-Ion Battery Industry Chain and Standards Development Forum

In recent years, sodium-ion batteries have gained momentum due to their abundant raw materials, low cost, strong temperature adaptability, and high safety profile. More than 200 companies have already entered the sodium-ion battery industrial chain.

To accelerate industrialization and promote standards development, the China Electronics Standardization Institute (CESI) and the China Energy Storage Alliance (CNESA) will jointly host the 4th Sodium-Ion Battery Industry Chain and Standards Development Forum in September 16-18, 2025 in Weihai, Shandong Province. The forum will focus on sodium-ion battery standards, technology R&D, and industry trends. Key leaders from the Department of Standards Technology Regulation of State Administration for Market Regulation (SAMR), MIIT, and senior experts and academicians are expected to attend.

At the forum, the sixth batch of certified sodium-ion battery units, the second batch of batteries that have passed 1000-cycle life testing, the first batch of low-temperature performance evaluation participants (tentative) will be released. CESI Laboratory is responsible for the testing, conducted in accordance with the T/CNESA 1006—2025: General Specification for Sodium-Ion Batteries, a CNESA group standard.

About Wendeng District, Weihai City, Shandong Province

Wendeng District, located in Weihai City, derives its name from the phrase “summoning scholars to ascend the mountain,” a reference to Emperor Qin Shi Huang’s eastward expedition. Covering a total area of 1,616 square kilometers, the district is home to a population of 548,000. Strategically positioned at the eastern tip of the Shandong Peninsula, Wendeng borders the Yellow Sea to the south and sits at the heart of the Qingdao–Yantai–Weihai economic triangle. Facing Korea and Japan across the sea, it serves as a core area of China’s national development strategy for the Shandong Peninsula Oceanic Economic Zone and the China–ROK Free Trade Zone Local Economic Cooperation Demonstration Area. Wendeng boasts a comprehensive multimodal transport network across land, sea, and air. Major highways such as the Weiqing Expressway, Wenrong Expressway, Wenlai Expressway, and National Highway 206 run through the district. It is also served by the Wendeng East Station on the Qingdao–Rongcheng intercity railway, Wendeng Station on the Jinan–Weihai railway, Wendeng South Station on the Laixi–Rongcheng high-speed railway, and Weihai Nanhai Station. Within a two-hour drive are five national Class I open ports and three international airports. Weihai International Airport, located in Dashuipo Town within the district, is a dual-use military and civilian airport operating over 590 flights weekly, with more than 20 domestic and international routes. A flight to South Korea takes just 45 minutes. Wendeng offers a first-class business environment. All administrative approvals can be processed through a single service window. Its innovative “Four Lists” service mechanism for supporting high-quality enterprise development has been recognized and promoted by the State Council’s inter-ministerial office for easing enterprise burdens. The district’s initiatives in business registration reform and enhanced regulatory oversight have also received commendation from State Council supervision efforts. The district has a solid industrial foundation, anchored by four key sectors: automotive and electromechanical equipment, new energy and new materials, pharmaceuticals and health foods, and electronic information. It is home to 250 industrial enterprises above the designated size and 143 enterprises that have been recognized at the provincial or national level as “Specialized, Refined, Differential, and Innovative” (SRDI), single-product champions, or high-growth “gazelle” companies.

The new energy and new materials sector focuses on niche areas such as battery electrolytes and electrode materials, photovoltaic power generation and equipment manufacturing, and pumped-storage hydropower. Wendeng has launched a diversified energy storage industrial base. The Wendeng Pumped Storage Power Station, the largest of its kind in the province by installed capacity, is now in operation. Wendeng is also Shandong’s only national pilot county for rural energy transformation. The automotive and electromechanical industry emphasizes critical components for commercial vehicles, new energy vehicles, special-purpose vehicles, and RVs. Its commercial vehicle parts cluster has been recognized as a national-level distinctive industrial cluster for small and medium-sized enterprises.

Its pharmaceutical and health food industry targets the development of medical materials, aesthetic medicine, modern Chinese medicine, innovative pharmaceuticals, and green, nutritious, and functional food products. The electronic information sector focuses on fiber optic cables and electronic components. The Nanhai New Area is a model eco-industrial zone that has won the UN-Habitat Award for Excellence in China. It has also been designated as a provincial-level eco-industrial park and a near-zero carbon zone.

Wendeng’s leading new energy and new materials sector is clustered around a one-square-kilometer industrial park, which has attracted more than ten major projects including Hanxing sodium-ion batteries, Nanhai New Energy anode materials, and Hengsheng lithium batteries. The district is building a multi-energy complementary system integrating wind, solar, energy storage and hydrogen production, alongside a source-grid-load-storage industrial ecosystem. In particular, a complete sodium-ion battery industry chain has been established, supported by supporting projects such as the Sinotrans Chemical Logistics Park, aiming to create an industry cluster with an output value exceeding RMB 10 billion. The Nanhai Port is planned to support a 300,000-ton main channel, with two 10,000-ton berths already completed. In the near term, the district will promote the construction of 50,000-ton general-purpose berths and port-rail links, providing efficient logistics support for raw material transport and product export in the sodium-ion battery sector.
