The Zhuhai Weilan semi-solid battery production line project, which has been put into production, is located at the Haida New Energy Base in Zhuhai City. It is driven by Guangdong Weilan Energy Technology Co., Ltd. to rapidly convert technological achievements. The company was jointly established by Guangdong Energy Group and Beijing Weilan New Energy Technology Co., Ltd. (the solid-state battery technology industrialization platform of the Institute of Physics, Chinese Academy of Sciences, and a national-level specialized and innovative "little giant" enterprise).

It is understood that the production line manufactures 314Ah large-capacity semi-solid-state batteries, which innovatively apply nano solid-state electrolyte technology, significantly increasing the thermal runaway initiation temperature and achieving a comprehensive upgrade in safety performance. By adopting a hybrid solid-liquid electrolyte formulation and in-situ curing technology, the batteries further enhance thermal stability and cycle stability, ensuring safe and stable operation even in extreme environments. Additionally, the 314Ah large-capacity semi-solid-state battery extends the thermal runaway trigger test time by over 40% compared to traditional batteries, reaching industry-leading safety performance levels.

During the ceremony,Zhang Fan, Secretary of the Party Committee and Chairman of Guangdong Energy Group.In the speech, it was stated that the group is fully committed to implementing the provincial party committee and provincial government’s strategic deployment of making the new energy storage industry a strategic pillar industry for the province's "manufacturing-led" development. The group is comprehensively implementing the "123 High-Quality Development Strategy" and systematically constructing a full industrial chain development layout for solid-state battery storage, which includes "innovation research and development - intelligent manufacturing - scenario applications."

Semi-solid battery production line

The newly launched Guangdong's first semi-solid-state energy storage battery production line has given birth to the world's first mass-produced high-capacity 314Ah semi-solid-state battery. This landmark achievement is the result of a collaboration between Guangdong Energy Group, Zhuhai City, Beijing Weilan, and Haistar Company. It marks a crucial step forward for the group in the field of high-end new energy manufacturing. It will surely provide safer and more efficient energy solutions for energy storage scenarios on the source-network side and urban user side, and contribute to the cultivation and growth of Guangdong's new energy storage industry.

The Group will fully leverage the professional platforms of the energy storage company, Guangdong Weilan Energy Company, and the fund company to innovate demonstration application scenarios and promote achievements. It aims to create a batch of semi-solid battery demonstration application projects with industry influence and technological leadership, becoming a vanguard in driving the development of new quality productivity in the energy sector. This will continuously inject green momentum into local economic development.

Su Hu, Vice Mayor of Zhuhai CityThe Zhuhai Municipal Party Committee and Municipal Government actively implement the development strategy of the new energy storage industry in Guangdong Province, promote the action plan for the development of the solid-state battery industry, and create a benchmark, innovative, and demonstrative solid-state battery industry cluster.

Currently, Zhuhai City is focusing on key technologies such as solid electrolyte materials, ultra-thin solid electrolyte membrane preparation, and semi-solid-state batteries with energy density exceeding 350Wh/kg. The city plans to integrate local enterprise resources, promote collaborative innovation across the upstream and downstream of the industrial chain, and strive to establish a pattern centered on the production and manufacturing of semi-solid and solid-state batteries. This initiative aims to drive the coordinated development of supporting enterprises in separator materials and production equipment, thereby building a closed-loop ecosystem of "R&D-production-application."

The commissioning of Guangdong's first semi-solid-state energy storage battery production line marks the mass production of the world's first 314Ah large-capacity semi-solid-state battery product. Inject strong momentum into the breakthrough of Zhuhai's solid-state battery industry development, and provide a solid foundation for the Guangdong-Hong Kong-Macao Greater Bay Area to build a world-class advanced manufacturing cluster.

Wang Xiaoyun, member of the Party Committee and Deputy Director of the State-owned Assets Supervision and Administration Commission of Guangdong ProvinceThe provincial Party committee and government have listed the new energy storage industry as a strategic pillar industry for "making制造业当家" (becoming the mainstay of manufacturing), and are fully committed to building an ecosystem for the energy storage industry. Currently, the completeness of the energy storage industrial chain in the province ranks among the top in the country.

The commissioning of Guangdong's first semi-solid-state energy storage battery production line marks another milestone in the province's efforts to implement the national "dual carbon" goals and the strategic deployment of building a new power system, advancing the transition to green energy.The launch and operation of this production line will further enhance Guangdong's R&D capabilities in cutting-edge technologies such as semi-solid and solid-state batteries, supporting the Guangdong-Hong Kong-Macao Greater Bay Area in building a world-class energy storage industry cluster.

The Provincial SASAC will continue to support Guangdong Energy Group in giving full play to the combined advantages of provincial state-owned enterprises in terms of capital, policy, and market. It will join hands with national high-tech enterprises and national specialized, refined, new "little giant" enterprises to achieve strong alliances and complementary advantages, and accelerate the investment and development layout of strategic emerging industries in the new energy storage sector of Guangdong Province.

The responsible comrades from the Guangdong Provincial Development and Reform Commission, Guangdong Provincial Industrial and Information Technology Department, Guangdong Provincial Emergency Management Department, Guangdong Provincial State-Owned Assets Supervision and Administration Commission, Guangdong Provincial Market Supervision Administration, and relevant departments of Zhuhai City, as well as heads of various departments at the group headquarters, relevant management units, and representatives from related enterprises attended the ceremony.
