Core Viewpoint - The announcement of the share reduction by the controlling shareholder of Daoshi Technology coincides with the company's technological breakthroughs in solid-state battery materials, raising questions about the company's short-term outlook and investment in R&D [1][2][3]. Group 1: Shareholder Actions - The controlling shareholder, Rong Jihua, plans to reduce holdings by up to 15.42 million shares, representing 1.97% of the total share capital, citing "personal funding needs" [1]. - After the reduction, Rong Jihua's shareholding will decrease from 16.19% to approximately 14.2% [1]. Group 2: Technological Developments - Daoshi Technology has made significant progress in solid-state battery core materials, achieving a breakthrough in sulfide electrolyte conductivity of over 1 mS/cm and stable production at the 100-gram level [1]. - The company has established a comprehensive material solution covering the entire solid-state battery industry chain, including single-wall carbon nanotube conductive agents and silicon-based anodes [1]. Group 3: Financial Performance - In 2024, Daoshi Technology's revenue is projected to be 7.752 billion, a year-on-year increase of 6.25%, with a net profit of 157 million, marking a turnaround [2]. - However, R&D expenditure for 2024 is expected to be 239 million, down 16.7% year-on-year, with R&D spending as a percentage of revenue at only 3.1%, significantly below the industry average of 5%-8% [2]. Group 4: Market Context and Challenges - The global solid-state battery market is expected to reach a scale of 100 billion by 2030, with Daoshi Technology at a critical technological breakthrough point [3]. - The company aims to achieve stable supply of kilogram-level sulfide electrolytes by 2025, but current production levels are insufficient compared to industry needs [2][3]. - The company faces headwinds in its main businesses of lithium battery materials and ceramic materials, with a decline in output of ternary precursors and a drop in ceramic material sales due to a sluggish recovery in the real estate sector [2].

【DT新材料】 获悉，4月23日， 道氏技术 发布公告，2025年第一季度，公司实现营业收入为17.58亿元，同比下降12.17%；归母净利润为4273.36万 元，同比大幅上升206.86%；扣非归母净利润为3576.83万元，同比大幅上升266.60%。 受全球新能源材料市场竞争加剧及下游需求阶段性波动影响。尽管公司 三元前驱体和阴极铜 出货量同比增长（三元前驱体出口1.8万吨，+137%）， 但产品价格受行业供需格局调整承压，导致收入规模收缩58。受益于 金属铜市场价格高位运行 （刚果子公司阴极铜产量19,674吨，+61%）及存货跌 价准备减少，叠加规模化生产摊薄成本，推动毛利率显著改善，支撑净利润高增。 | | 本报告期 | 上年同期 | 本报告期比上年同期增减 | | --- | --- | --- | --- | | 营业收入(元) | 1,758.117,781.59 | 2.001.701.468.85 | -12.17% | | 归属于上市公司股东的净利 | 43.733.567.84 | 14,252,078.70 | 206.86% | | 润(元) | | | | | 归属于上市公司 ...

下游新能源汽车和储能市场发展日益成熟，对锂离子电池性能要求逐步提高，推动锂离子电池技 术向高能量密度、高安全性更新迭代升级。导电剂作为锂电池的组成材料，锂电池的更新迭代对 导电剂性能也提出了更高的要求。碳纳米管是由单层或多层的石墨烯层围绕中心轴按一定的螺旋 角卷曲而成一维量子材料，作为新型导电剂，具有导电性强的优异功能，比传统导电剂（如炭 黑、导电石墨等）能更好地提高正极活性物质的导电性，能够提升电池能量密度，提升电池循环 寿命。碳纳米管的长径比、碳纯度作为影响导电性的两个核心指标，直接决定了碳纳米管的产品 性能，碳纳米管管径越细，长度越长，导电性能越好。 碳纳米管根据石墨烯层数差异可以分为单壁碳纳米管和多壁碳纳米管。 单壁碳纳米管优势体现为： 5）弹性好、机械性能高：单壁碳纳米管具有更强的柔韧性，能够更好的弯曲、扭曲或扭结，其 弹性模量和抗拉强度显著优于多壁碳纳米管。 6）导热性好：单壁碳纳米管的单位质量导热系数高于多壁碳纳米管，同时二者都能够承受 750°C以上的高温。 单壁碳纳米管大规模化量产目前还存在以下难点： ①产品性能难以精准调控：单壁碳纳米管的性能与其直径和手性密切相关。大部分样品是由多种 具有 ...
