（文章来源：证券日报） 证券日报网讯瑞丰高材10月27日在互动平台回答投资者提问时表示，电池负极材料是黑磷重要的下游应 用领域，公司已经围绕电池负极材料做了大量研发工作。通过将黑磷与石墨等材料按优化比例进行机械 球磨复合，可制备高性能磷碳负极材料。公司也同步在做磷碳负极材料的性能测试，包括非固态电池和 固态电池体系。实验结果表明，磷碳负极材料可以匹配应用到固态电池体系中。公司高度重视黑磷业务 的发展，但目前尚处于产业化的初期阶段，短期内预计不会对公司业绩产生重大影响。 ...

Group 1 - The company has conducted extensive research on battery anode materials, particularly focusing on black phosphorus as a significant downstream application [2] - The company has developed high-performance phosphorus-carbon anode materials by optimizing the mechanical ball milling process with black phosphorus and graphite [2] - Performance testing of phosphorus-carbon anode materials is being conducted for both non-solid-state and solid-state battery systems, with results indicating compatibility for solid-state applications [2] Group 2 - The company places high importance on the development of its black phosphorus business, although it is still in the early stages of industrialization [2] - Short-term expectations indicate that the black phosphorus business will not have a significant impact on the company's performance [2]

Core Viewpoint - 瑞丰高材 is focusing on the industrialization of black phosphorus as a negative electrode material, which has significant advantages over traditional materials like graphite and silicon-carbon [1][2]. Group 1: Black Phosphorus Technology and Advantages - Black phosphorus has a theoretical specific capacity seven times that of graphite, and its volume expansion during lithium intercalation is approximately 200%, which is lower than that of silicon-based materials [1]. - The company is advancing the industrialization of black phosphorus, with a ton-level pilot production line expected to be operational in the third quarter of this year [1][2]. - The optimized phosphorus-carbon negative electrode exhibits excellent long-cycle stability and can be used in solid-state battery systems [1]. Group 2: Challenges and Innovations - The low-cost industrialization of black phosphorus faces significant challenges, particularly in controlling high-temperature and high-pressure environments [2]. - 瑞丰玥能, the company's subsidiary, has nearly ten years of technical reserves and has successfully improved the reaction conditions, increasing product yield and efficiency [2]. Group 3: Business Segments and Financial Performance - 瑞丰高材 has four main business segments: plastic additives, polyester materials, new energy materials, and synthetic biological materials [3]. - The engineering plastic additives segment is projected to achieve revenue of 107 million yuan in 2024, representing a year-on-year growth of 212% [3]. - The company is also working on increasing the production capacity of its recognized products, such as right-handed sugar acid [3].
