Author: Liu Ze typesetting: Dotting the "map" of the industry Shouting for the industry's "sodium" --- 2024 starting point sodium electricity national research and interview activities are in full swing. The 2024 National Research and Interview Activity is organized by the National Research and Interview ActivityMengshi Technology, Shangshui Intelligence, Rute Technology, and Pushida are sponsored and supportedIt will continue to be carried out from January 2024 to March 2024 to conduct research and interview exchanges with leading enterprises in various subdivisions of the sodium battery industry chain, conduct in-depth research on the development and dynamics of the sodium battery industry, report and publicize high-quality enterprises, and promote the development of the sodium battery industry into a new stage. On March 5th, the starting point sodium electricity research group walked into the sodium source and had in-depth exchanges with Liu Honggan, deputy general manager of the company. 
Figure: Group photo of the starting point sodium power research group and China sodium source) China sodium source energy storage technology was established in April 2021, mainly engaged in the research and development, production and sales of sodium-ion battery anode materials. In November 2022, Changzhou Zhongnayuan New Material Technology Co., Ltd. was established in LiyangIt has launched hard carbon products with a capacity of 330mAh g and a first effect of 92%, with an annual production capacity of 1,000 tons, and the goal is to achieve 10,000 tons of intelligent factory production and operation in 2024. The research and development of sodium source is mainly responsible for the chief scientist Professor Hong Zhensheng, who is a doctor of materials chemistry and has been engaged in the research of sodium-ion battery electrode materials for a long time, has published a total of 90 SCI articles, and has 25 national invention patents authorized by the first inventor. Liu Honggan said that at present, domestic high-quality hard carbon depends on Japanese imports, and it is expensive, which restricts the industrialization process of sodium-ion batteries and the independent and controllable technology. In view of the pain points of the industry, the solution of the medium sodium source is to select low-cost resin as raw material to solve the problem of ash content and consistency; Modify the raw materials and improve the rate of the product; Increase the processing technology of the product, provide the stability of the product, and extend the number of cycles; shorten the processing time, reduce the processing cost, and improve the cost performance of the product; Targeted development of specific products to broaden the product application market. Liu Honggan introduced that resin-based hard carbon has the advantages of high capacity, high initial efficiency, high tap density, short manufacturing time, simple and low cost, wide range of raw materials and high purity, high product consistency, and is conducive to large-scale manufacturing. The raw material of resin-based anode material is a petrochemical by-product chemical synthesis resin, with an annual output of tens of millions of tons and a raw material purity of 9999%, stable cost. The result is a product with a high capacity (300 350) and high consistency. The cost is controllable and moderate (comparable to the cost of lithium battery anode artificial graphite). Liu Honggan said that according to the experience of lithium battery cathode and anode, with the improvement of the capacity of sodium battery cathode materials, high-capacity anode materials can meet the needs of sodium battery development in the future. The anode material developed by the company has high capacity, high consistency, easy large-scale production, controllable cost and high cost performance, which is in line with the future development direction of sodium electricity. At present, Zhongnayuan has established daily exchanges with the chairman, general manager and R&D director of nearly 40 companies in the domestic sodium-ion battery industry, and has supplied samples to nearly 30 companies.
