On February 18, the "thousands of trillions" major projects in Zhejiang Province were put into operation and put into operationZhejiang Zhongning Silicon Industry silicon carbon anode materials and high-purity silane series products project also started on the same day. Zhejiang Zhongning Silicon Industry silicon carbon anode materials and high-purity silane series products project is located in Quzhou, Zhejiang, with a total investment of 52800 million yuan, after the project is put into operation, it will form an annual production capacity of 40,000 tons of silicon carbon anode materials. 
Zhejiang Zhongning Silicon Industry Co., Ltd. is the first domestic enterprise to produce electronic-grade polysilicon by silane method, and is also a holding subsidiary of the listed company Duofluoride. According to the 2023 semi-annual report of Duofluoride, in the main financial information of important non-wholly-owned subsidiaries, the net profit of Zhongning Silicon ranks first among the 11 non-wholly-owned important subsidiaries of Duofluoride, which is an important part of its layout of new energy materials. It is understood that Zhongning Silicon Industry is a pioneer enterprise in the field of high-purity nano silicon powder in China. In 2019, the company built a production line with an annual output of 200 tons of nano silicon powder and 100 tons of silicon carbon materials, and the purity of the high-purity nano silicon powder produced by the company is as high as 9999% with a particle size between 20-100nm. The controllable and large-scale preparation of nano-silicon powder also provides a guarantee for Zhongning Silicon Industry to realize the subsequent production of silicon-carbon anode materials for lithium-ion batteries. Silicon carbon anode has the advantages of high theoretical capacity, high first charge and discharge efficiency, low process cost, etc., and is an important development direction of the next generation of anode materials.
In January this year, CATL published an international patent application titled "Silicon Carbon Composite Materials and Negative Electrode Pieces Containing Them". Prior to this, BYD also applied for a patent called "silicon anode material and its preparation method, anode piece, battery and electrical equipment".
In addition, old anode material companies such as beiteri, Shanshan Co., Ltd., and Putailai have realized the production capacity of silicon carbon anode.
At present, Shanshan Co., Ltd. has realized the industrial application of silicon-based anode products, and its integrated base of silicon-based anode materials with an annual output of 40,000 tons of lithium batteries has also settled in Ningbo.
Beiteri's silicon-based anode material has broken through to the third generation of products, and the specific capacity has been increased to 1500mAh g.
Putailai also said that its technology in the pretreatment of silicon carbon anode raw materials is at the forefront, with good product stability and high technical maturity, and is widely recognized by leading key customers.
Institution**, with the mass production of high-density power battery products using silicon carbon anode by special battery companies, the silicon carbon anode market will usher in a blowout, and the global shipment of silicon carbon anode will reach 14 in 202590,000 tons.
