According to Xiangjiang Guotou, recentlyXiangjiang New Area Industry**Completed the completion of Hunan Sodium New Materials, hereinafter referred to as "Sodium New Materials").Pre-A round of investmentThis round of financing will be mainly used for R&D innovation, capacity expansion and talent introduction. According to the data, Sodium New Materials was established in December 2022 and is a technological innovation enterprise cooperated by Wasion Group's related industries and Central South University, focusing on the research, development and production of hard carbon anode materials for biomass-based sodium-ion batteries. 
As early as 2012, the team began to lay out the research of sodium-ion batteries, and in February 2023, the company's R&D base was put into operation, the construction of the pilot production line of hard carbon anode materials was started in March, and the construction of the 10,000-ton production base was started in September. In January 2024, the pilot production line of Nake New Materials will be put into operation, which is located in the Lugu Manufacturing Demonstration Park, Xiangjiang New District, Changsha City, Hunan Province, with a construction area of 6,000 square meters, and the production line can be formed after reaching productionThe annual production capacity of 1,000 tons of biomass-based hard carbon anode materials。In the next three years, Nake New Materials is expected to increase investment by 1.3-1.5 billion yuan to build a 50,000-ton hard carbon anode material production base and form a standard quantitative base with an annual output value of 2 billion yuan. The company has gathered a professional team of development and industrialization led by Professor Tang Yougen, director of the Hunan Provincial Key Laboratory of Chemical Power Sources of Central South University, and has developed multiple generations of market-competitive hard carbon anode material products. Among them, the first-generation low-cost sodium electrohard carbon anode material has a specific capacity of more than 300mAh g, and the first effect is about 90%, which has the advantages of low cost and high cost performance. The specific capacity of the second-generation hard carbon anode material is more than 330mAh g, and the first effect is about 92%, which has the advantages of good performance, low cost and balanced cost performance. The specific capacity of the third-generation high-end customized hard carbon anode material can reach 400mAh g, and the first effect is greater than 88%.Excellent performance. The technical advantages of Nake new material products are mainly reflected in five aspects: Purification technology: acid and alkali washing to remove metal impurities, improve cycle life and safety; Cross-linking curing and pre-carbonization technology: improve the carbonization rate, adjust the micropore structure, and improve the hard carbon capacity and power performance; Spherical technology: reduce the specific surface area of hard carbon materials, improve the first coulombic efficiency, and increase the tapping density; Surface modification technology: use deoxidation, coating and other means to improve the efficiency of the first coulomb; Incoming material inspection and control technology: screening high-quality biomass carbon sources through molecular weight, crystallinity and other parameters. Up to now, Natech New Materials has completed the sales and delivery of tonnage hard carbon anode materials, and completed multiple rounds of sample delivery and verification to more than 15 companies such as CATL, BYD, Trina Energy Storage, EVE Lithium Energy, Tianneng Group, Hunan Cube, Hunan Desay, Changde Kunyu, etc., and has also reached a strategic cooperation agreement with Xingheng Power. Tianna Technology completed tens of millions of yuan in financing
On February 4, Wuhan Tiannai Technology Co., Ltd. officially announced the completion of tens of millions of yuan in angel ++ round of financing, which was invested by Fuyang Fuhe Angel Investment ** Partnership (Limited Partnership) and will be mainly used for production line construction. So far,Tianna Technology has received financing of nearly 100 million yuanIn December 2022, Tianna Technology also received an angel round of financing, with investors including Meituan, Jinglin, Hefei Innovation Investment, etc. According to the data, Tianna Technology was established in 2017, mainly engaged in the design, research and development, production and sales of high-safety, low-cost, long-life sodium-ion battery anode materials, and at the same time developed sodium cathode materials, electrolytes and sodium battery cell technology, providing a complete set of solutions for sodium battery upstream materials. The company's project team has many years of experience in the research and development of hard carbon materials and technology precipitation, using chemical small molecule polymerization + high-temperature carbonization process, supplemented by PDF characterization technology to regulate the hard carbon micro-nano structure, and guide the direction of product iterationWe have developed high-performance products with a first effect of more than 90% and a specific capacity of more than 400mAh g. Since its establishment, the company has completed the R&D and pilot test of a number of hard carbon anode material products, and the products have been sent to a number of downstream battery cell factory customers for sample testing and approval. companyA production base of 2,000 tons of anode materials has been builtIt is expected to be put into production in the first quarter of 2024 and can be sold in batches, and the Pre-A round of financing will be launched on an elective date. The R&D headquarters of Tianna Technology is located in Wuhan Optics Valley, and Hefei Tiannada Materials undertakes the production of sodium-ion battery powered cathode and anode materials, and Fuyang Tiannada Energy undertakes the production of sodium-ion battery energy storage cathode and anode materials. 
In February 2023, Tianna Technology invested in the establishment of a wholly-owned subsidiary, Hefei Tianna, which is located in the Equipment Manufacturing Industrial Park, High-tech Zone, Lujiang County, Hefei City, Anhui Province, and will invest about 7500 million yuan, the construction of 50,000 tons of sodium-ion battery power hard carbon anode production line. In July, Fuyang Tianna Energy was established, the company is located in Fuyang Hefei Modern Industrial Park, Fuyang City, Anhui Province, with a total investment of about 1.5 billion yuan, and will build a 100,000-ton sodium-ion battery energy storage hard carbon anode production line. More than 10 hard carbon anode material companies have been supported by capital
According to the incomplete statistics of the starting point of sodium electricity, in addition to Tianna Technology and Nake New Materials, there are dozens of sodium electric hard carbon anode material companies such as Baisige, Guoke Tanmei, Jia Na Energy, Carbon Jia Technology, Rong Na New Energy, Dongjian Sodium Storage, Hanxia Technology, Carbonn and so on. 
There are many technical routes for sodium electrode materials, but in terms of comprehensive performance and cost, biomass hard carbon is the most promising sodium electrode material for mass production. According to estimates, the hard carbon anode accounts for about 25% of the cost of sodium batteries, and the main enterprises with mature product technology are Japanese companies such as Kuraray and Kurea Chemical, with an import cost of more than 200,000 tons, and the current domestic production capacity is relatively limited, so the anode material has become one of the main factors restricting the large-scale production of sodium batteries. At present, more than 45 enterprises have launched a layout in the field of sodium electric hard carbon anode materials, with a total planned production capacity of more than 600,000 tons, of which Shengquan Group, Tianna Technology, Guoman Sodium Electricity, Rongna and other enterprises have a planned layout of more than 100,000 tons, and more than 230,000 tons of sodium electrode anode material projects will be signed and started in 2023 alone. With the advancement of the industrialization of sodium battery anode, related orders have gradually begun to rise, and Biruman Nadian has won a large-scale purchase order of 100,000 tons of sodium battery anode materials from Hongxinda. Technological breakthroughs, large-scale production and material cost reduction of sodium battery anode materials are one of the keys to the development of sodium battery industry, and with the support of capital, the industrialization of sodium battery anode materials will be accelerated, and the industrialization process of sodium batteries will also be promoted.
