2. Cooperation Background: Mutual Empowerment Under Industrial Transformation
Against the backdrop of the accelerated global energy structure transformation towards green and low-carbon development, PowerChina Jiangxi Provincial Hydropower Engineering Bureau New Energy Engineering Company's decision to reach a strategic cooperation with CNAE China Sodium-Ion Battery Group focuses on two core considerations:
"the irreplaceability of technical performance" and "the strategic forward-looking of large-scale energy storage applications".
This cooperation is not only a full recognition of CNAE's three core technical advantages of sodium-ion batteries—"safety, low-temperature resistance, and fast charging"—but also a key move by the central enterprise in its layout of the new energy track.
(1) PowerChina Jiangxi: The "Hard Power" of Central Enterprise Engineering
As a core engineering bureau under PowerChina, PowerChina Jiangxi has been deeply engaged in energy infrastructure construction for 67 years. Since establishing its New Energy Engineering Company in 2015, it has undertaken 32 photovoltaic power stations and 21 wind power projects, with a total installed capacity exceeding 3GW, including:
Benchmark Project: Qinghai Talatan 500MW Photovoltaic Project (China's first large-scale high-altitude photovoltaic base)
Technological Breakthrough: Independently developed "mountain photovoltaic intelligent construction robot" won the first prize of China Electric Power Science and Technology Progress in 2022
Energy Storage Layout: The 50MW/100MWh energy storage power station built and put into operation in Xinyu, Jiangxi in 2021 has an operating efficiency of 89.3%, ranking among the industry's top.
(2) CNAE China Sodium-Ion Battery Group: The "Technical Leader" in the Sodium-Ion Battery Industry
With its "Three-Resistance" battery technology, full-industry-chain layout, and global capacity expansion, CNAE China Sodium-Ion Battery Group has become a technical leader in the sodium-ion battery field and is widely recognized as a Top 2 practical leader in the industry.
Technological Leadership
CNAE China Sodium-Ion Battery Group adopts dual technical routes of polyanion and layered oxide, launching 32140 large cylindrical cells, 4695-type sodium-ion batteries, and 280 blade cells. The energy density of sodium-ion batteries has reached 142Wh/kg, and the third-generation layered oxide has an energy density of 167Wh/kg.
It also provides ecological energy storage solutions, adapting to diverse scenarios such as home energy storage, outdoor power supplies, and electric motorcycle batteries. Its energy storage systems cover home storage, industrial-commercial storage, and large-scale power stations, with low-temperature performance (normal operation at -40℃) meeting the needs of extreme environments.
Practical Leader
Currently, CNAE China Sodium-Ion Battery Group has built a 1GWh 32140 large cylindrical production line, which is operating at full capacity. The entire production line can achieve a daily output of more than 50,000 cells, with mass production scale ranking among the top in the sodium-ion battery industry.
This year, CNAE China Sodium-Ion Battery Group has launched the Phase II capacity expansion plan, which will add another 2GWh to the existing 1GWh capacity at the Yangzhou base.
In terms of project progress, CNAE China Sodium-Ion Battery Group is actively promoting the construction of the Phase II project.
It is expected that by the end of this year, CNAE China Sodium-Ion Battery Group will form an initial mass production scale of 3GWh; by March 2026,it will initially achieve a daily production capacity of nearly 150,000 cells.
3. Driving Globalization Through Innovation, Leading the Transformation of the Sodium-Ion Battery Industry
As a core enterprise in China's sodium-ion battery field, CNAE China Sodium-Ion Battery Group has always adhered to the development philosophy of "technology leadership, industrial service to the country, and global layout", committed to promoting the large-scale application of sodium-ion battery technology in energy storage and power fields through technological breakthroughs, capacity upgrades, and market development.
Amid the wave of accelerated transformation in the new energy industry, we take low cost, high safety, and environmental adaptability as core advantages, plan the future with a global perspective, and strive to rank among the world's top three sodium-ion battery enterprises by 2027, injecting strong momentum into the high-quality development of China's new energy industry.
The historical experience of large-scale expansion of Chinese industrial enterprises shows that capital support, government backing, and market recognition are the three pillars of industrial take-off.
CNAE China Sodium-Ion Battery Group deeply understands this and is promoting the maturity of the sodium-ion battery industry ecosystem with systematic strategies:
Capital Empowerment to Accelerate Capacity Expansion: Focus on the construction of Phase II of the Yangzhou production base, aiming to achieve a 3GWh capacity target in 2025. Large-scale production will significantly reduce marginal costs and further consolidate price competitiveness.
Leveraging Policies to Build an Industrial Ecosystem: Actively respond to the national "dual carbon" strategy, keep up with the pace of battery digital intelligence, seize policy dividends, and pave the way for the large-scale development of the industry.
Technology as the Spear, Reputation as the Shield: CNAE focuses on two main markets—sodium-ion battery product R&D and energy storage—and has signed orders exceeding 800 million yuan with enterprises such as Wuling Industry and Zhongcheng Dayou. Through cost-effective products and customized services, it gradually replaces traditional lead-acid batteries and lithium-ion batteries, winning customer reputation and market share.
4. International Strategy: From Leading China to Leading the World
China's new energy industry has stood at the global technological high ground. Although the technical development of sodium-ion batteries at home and abroad is converging, the domestic industrialization speed is far ahead.
Based on local technological advantages, CNAE China Sodium-Ion Battery Group is actively exploring the international market:
Focusing on production line commissioning and quality control upgrading, it has completed product certifications in target markets such as Southeast Asia and Europe, and established an overseas compliance system. The stable mass production at the Yangzhou base in Jiangsu has laid a capacity foundation for exports.
Starting from the second half of this year, CNAE China Sodium-Ion Battery Group will also target overseas markets and plan to fully expand its sodium-ion battery products in overseas regions such as Southeast Asia, Europe, the Middle East, and parts of Africa.
In the initial phase, it will focus on high-demand scenarios such as electric tricycles and overseas home energy storage in Southeast Asia, quickly implement projects through localized cooperation, and shape a brand image of "high safety, long lifespan, and low cost".
At the same time, through a combination of international exhibitions, benchmark projects, and high-end product exports, it will fully demonstrate the technical value of Chinese sodium-ion batteries, break the overseas market's dependence on traditional battery paths, establish a new benchmark for "Made in China", and achieve localized overseas applications.
