SMM March 17 News:
In the era of rapid technological advancement, innovation in battery technology has become a key driver of global energy transformation. On January 20, 2025, Yancheng Sanhexin Technology Co., Ltd. was officially established. This dynamic and innovative company, focusing on polymer technology, successfully launched a battery anode material product—super hard carbon, marking a significant breakthrough in the lithium battery and sodium-ion battery fields.
Since its inception, Yancheng Sanhexin Technology has concentrated on the battery anode material sector, striving to address industry challenges through polymer technology innovation. The company has gathered top-tier scientific research talent in the industry and, through the team's professional expertise and relentless efforts, has overcome multiple technical challenges in a short period. Following the successful synthesis of kilogram-scale materials on February 20, the company achieved a breakthrough in the preparation of hundred-kilogram-scale materials on March 10, with product-related data meeting design requirements.
Super hard carbon demonstrates outstanding performance in lithium battery and sodium-ion battery tests. Lithium battery tests show a reversible capacity of up to 852mAh/g, leading the industry. Its high specific capacity provides stronger energy assurance for industries such as EVs and consumer electronics, significantly enhancing EV driving range and alleviating users' range anxiety, while also greatly extending the usage time of portable electronic devices. In sodium-ion battery tests, super hard carbon achieves a reversible capacity of 600mAh/g, effectively addressing the issue of low volumetric density in traditional hard carbon, which impacts the overall energy density and cost-effectiveness of sodium-ion batteries. With the growing global demand for renewable energy and the tightening of lithium battery resources, its excellent performance provides strong support for the commercialization of sodium-ion batteries, with broad prospects in ESS, EV low-temperature applications, and other fields.
On the cost side, super hard carbon has significant advantages, with costs around 60,000 yuan. Compared to traditional high-end anode materials, it ensures high performance while effectively controlling costs, reducing procurement costs for battery manufacturers, enhancing product market competitiveness, and promoting the adoption of the new energy industry.
In technology R&D, the company leverages its polymer technology advantages to finely tune the microstructure and chemical composition of super hard carbon. By designing polymer chain segment structures, introducing specific functional groups, and combining them with CVD technology, the company optimizes the pore structure and electronic transmission channels of hard carbon materials, improving the diffusion coefficients of lithium and sodium ions and enhancing the charge-discharge efficiency and C-rate performance of electrode materials.
In market applications, super hard carbon has attracted the attention of numerous battery companies and research institutions. Many companies have provided high praise after trials and expressed intentions for collaboration. With the growing demand in the new energy battery market, it is expected to see widespread application in the lithium battery and sodium-ion battery fields.
Looking ahead, Yancheng Sanhexin Technology will continue to focus on high-tech fields, developing more high-performance battery anode material products based on super hard carbon. The company will also strengthen cooperation with research institutions, universities, and other enterprises to contribute to global energy transition and green development.
