Construction begins on Shanshan’s integrated project for producing 40,000 tons of silicon-based anode materials per year

Thread Content

According to a message on Shanshan’s official WeChat account, an event was held in Ningbo, Zhejiang, to mark the simultaneous commencement of major construction projects. The start of work on key projects such as the Shanshan lithium battery silicon-based anode material integrated production facility will further enhance Zhejiang Province’s entire new energy industry chain. It is reported that the total investment in this integrated silicon-based anode material project is 5 billion yuan, covering all stages from raw material processing, reaction synthesis, intermediate product processing, surface modification to final product manufacturing. The project is constructed in two phases; the first phase is planned to have an annual production capacity of 10,000 tons, with a construction period of approximately 12 months ； The second-phase project is planned to have an annual production capacity of 30,000 tons, with a construction period estimated at 12 months. Once fully built, it will be able to produce 40,000 tons of silicon-based anode materials for lithium batteries per year, with an estimated annual output value of 10 billion yuan. Silicon-based anode materials are key materials for the anodes of next-generation lithium-ion batteries, representing a critical technological advantage in this industry. Currently, in the fields of power tools, high-end electronics, and battery packs, the penetration rate of silicon-based anodes is increasing rapidly. With the gradual mass production of 4680 large cylindrical batteries, silicon-based anode materials are set to experience rapid growth. At present, there are very few companies in China that have truly achieved mass production and bulk supply of silicon-based anodes; most companies are still in the planning, pilot production, or research and development stage. Shanshan Technology was the first to develop silicon-based anodes, the first to achieve mass production of them, and the first to gain recognition from and receive orders from customers around the world. Ningbo Shanshan Silicon-Based Materials Co., Ltd. stated that this project represents Shanshan’s first R&D and production facility for pure, high-capacity silicon-based anode materials. Partial equipment commissioning for the project is scheduled to take place in the second half of this year, with partial operation starting in 2024 and full operation achieved by 2026. The successful expansion of this 40,000-ton integrated production facility will provide strong momentum for the rapid development of the new energy market, thereby breaking the dominant supply position held by foreign companies in the field of silicon-based anode materials.
