摘要 时间是盟友，更是壁垒。 2025 年的夏天，硅基负极进入了它的第二轮扩产周期。 反向赌注的开始 时间倒回至两年前，彼时硅基负极赛道热度初显。 基于多孔碳骨架和硅烷气、采用 CVD （化学气相沉积）法制备新型硅碳负极，能够实现高膨 胀率瓶颈的攻克，最终兼顾比能与循环性能——这一全新工艺路线的确定，让硅碳负极的产业 化前景豁然开朗。 在同样的积极气氛中，有一家硅基负极做出了一个让许多投资人费解的反向赌注。 彼时， 作为中科院物理所硅基负极唯一产业化平台的天目先导，已经基于长久以来纳米硅、 CVD 工艺上的先发认知与技术突破，完成了早期的产业探索。 第一轮是路线之争： 谁敢在多孔碳骨架上押注 CVD ，谁先把比容量做上去； 第二轮开始变成结构之争： 谁能在万吨级扩产、出海布局和头部客户绑定之间建立起真正的 护城河。 半年内，超过四百亿元的投资、四十万吨以上的规划产能涌入这一赛道，硅基负极从 "少数人 的选择题"变成"多数人的标配项"： 比容量普遍突破 2000mAh/g ，是传统石墨的五倍有余；百公斤级的流化床设备已进入产线 验证；部分企业甚至宣布自建、绑定上游硅烷气产能，以示其垂直整合的决心。 作为终端企业 ...

Core Viewpoint - The article discusses the strategic move of Shengquan Group to issue up to 2.5 billion yuan in convertible bonds, with 2 billion yuan allocated for the industrialization of green energy battery materials, particularly silicon-carbon anodes, indicating a significant commitment to the new energy sector [4][5]. Group 1: Company Strategy and Financials - Shengquan Group plans to produce 10,000 tons of silicon-carbon anodes and 15,000 tons of porous carbon annually, with production expected to start in the third year after a two-year construction period, projecting an average annual sales revenue of 3.948 billion yuan and a net profit of 756 million yuan [4]. - In the first half of the year, Shengquan Group achieved a revenue of 5.351 billion yuan, a year-on-year increase of 15.67%, and a net profit of 501 million yuan, up 51.19% year-on-year [5]. - The company has developed two technical routes for porous carbon materials, utilizing phenolic resin and restructured resin, to penetrate the mainstream battery supply chain [5][6]. Group 2: Industry Context and Competitive Landscape - The silicon-carbon anode is a key direction for enhancing lithium battery energy density, but its industrialization faces challenges related to process stability and cost [6][7]. - Shengquan Group's strategy includes a vertical integration approach, ensuring a stable supply of porous carbon, which is crucial for the production of silicon-carbon anodes, potentially giving it a competitive edge in the market [6][7]. - The industry is expected to see a significant increase in silicon-carbon anode production capacity between 2025 and 2026, with several leading companies, including Bettery and Putailai, also advancing their projects [7]. Group 3: Technological Advancements - Shengquan Group's unique biomass refining technology and resin preparation process have led to the development of competitive porous carbon materials, which enhance the uniformity of silicon deposition and improve the energy density of silicon-carbon anodes [8]. - The company’s spherical porous carbon technology is globally leading, featuring uniform and controllable pore structure, making it suitable for high energy density applications such as semi-solid and solid-state batteries [8].
