QYResearch has been closely monitoring the development of the porous carbon for silicon-carbon market. As new energy vehicle batteries, high-energy-density energy storage batteries, and mid- to high-end consumer electronics batteries continue to require higher energy density, faster charging capability, and longer cycle life, silicon-carbon anodes are progressing from advanced-material validation toward industrial-scale adoption. As a key carbon skeleton material in silicon-carbon anodes, porous carbon plays an important role in regulating silicon deposition, buffering volume expansion, optimizing ion-diffusion pathways, and improving cycle stability. It is evolving from a supporting material into a critical base material that increasingly defines the performance boundary of silicon-carbon anodes. This report examines product definitions, technology routes, market size, competitive dynamics, regional structure, application directions, and industry-chain developments in the global porous carbon for silicon-carbon market. Porous carbon for silicon-carbon refers to high-performance carbon skeleton materials used in silicon-carbon anode systems. These materials are generally produced from biomass, resin-based, pitch-based, coal-based, or related carbon precursors through carbonization, activation and pore formation, washing, drying, grinding, classification, and surface-regulation processes. These materials are characterized by high specific surface area, abundant pore volume, controllable pore structures, good electrical conductivity, high stability, and stringent batch-consistency requirements. Their primary function is to provide space for silicon deposition and dispersion within silicon-carbon anode materials. Through multilevel pore structures, porous carbon can buffer silicon volume expansion during lithiation and delithiation, improve electron transport and ion-diffusion efficiency, and enhance initial efficiency, rate performance, cycle life, and structural stability. From a material-performance perspective, the high specific surface area of porous carbon provides additional active sites and stronger silicon-loading capacity, while its complex pore network creates rapid lithium-ion diffusion channels. These characteristics help silicon-carbon anodes better balance high capacity with long-term cycle stability. Current silicon-carbon-related process routes mainly include mechanical ball milling, high-temperature pyrolysis, and chemical vapor deposition (CVD). Among these routes, CVD stores silicon within a porous carbon framework and uses internal voids to buffer expansion, demonstrating considerable potential in high-end silicon-carbon anode systems. Under this trend, porous carbon for silicon-carbon is becoming one of the most important focus areas in next-generation high-performance anode material systems.

The market scope primarily covers porous carbon skeleton materials used in silicon-carbon anode systems, particularly those applied in high-performance silicon-carbon composite routes. These materials include biomass porous carbon, resin porous carbon, pitch- and coal-based porous carbon, and other related high-specific-surface-area porous carbon materials. In 2025, global output of porous carbon for silicon-carbon was approximately 1,637 tons. The average selling price was approximately US$32,270 per ton, while the average gross margin was approximately 24.57%. From the demand perspective, market growth is mainly driven by accelerated adoption of high-energy-density power batteries, fast-charging battery upgrades, progress in silicon-carbon anode validation among leading battery manufacturers, and the performance upgrade of consumer electronics batteries. Power batteries represented the dominant application segment, accounting for more than 97% of total demand in 2025. Consumer electronics and other small-battery applications currently account for a relatively limited market share. However, these segments are expanding rapidly in premium portable devices, wearable devices, and high-rate battery applications. Overall, the industry remains in a high-growth stage, with future expansion expected to be driven by increasing power-battery volumes, deeper industrialization of silicon-carbon anodes, porous carbon structure optimization, and continued cost reduction. Competitive Landscape The global porous carbon for silicon-carbon market currently demonstrates a competitive structure characterized by Chinese suppliers dominating the supply side, overseas high-end carbon material companies maintaining technological expertise, and a growing number of domestic market entrants. Major global producers include Kuraray, Haycarb, Shengquan Group, Fujian Yuanli, Henan Dachao Carbon Energy Technology Co., Ltd., Sinosteel Maanshan General Institute of Mining Research, Aemcn, KBC Corporation, Ltd., Shanghai Tanyuan New Materials Technology Co., Ltd., Zhejiang Apex, Fujian Xinsen Carbon Co., Ltd., Bengbu Gifuli New Materials, Shenzhen Solide New Materials Technology Co., Ltd., Jiangsu PURESTAR Environmental Protection Technology Co., Ltd., Guangdong Dowstone Technology Co., Ltd., Shanghai Putailai New Energy Technology Co., Ltd., Do-Fluoride New Materials Co., Ltd., Xuancheng Silike New Materials Co., Ltd., Beihai Sence Carbon Materials Technology Co., Ltd., and Jiangxi Kete Carbon Based New Material Co., Ltd. According to QYResearch statistics, first-tier suppliers in 2025 primarily included Shengquan Group, Fujian Yuanli, Henan Dachao Carbon Energy Technology, Sinosteel Maanshan General Institute of Mining Research, Aemcn, and Shenzhen Solide. Together, these companies accounted for approximately 92.15% of global sales volume, indicating a high level of market concentration at the current stage. The core competitive strengths of leading suppliers are primarily reflected in carbon precursor selection, activation and pore-forming technologies, pore-size and pore-volume design, ash and metallic impurity control, consistency management, and joint development capabilities with downstream customers. First-tier companies have generally entered the validation systems of mainstream silicon-carbon anode companies or battery-material customers, establishing significant first-mover advantages and delivery capabilities. Second-tier players mainly originate from sectors including activated carbon, carbon materials, environmental adsorption materials, anode materials, and new energy materials. These companies are gradually entering the market through production-line modification, customer sampling, and new-project construction. As additional capacity comes online and new entrants expand, competition is expected to intensify. However, companies with strong capabilities in high-pore-volume structural design, low-impurity control, stable mass production, and downstream compatibility are expected to retain competitive advantages. Product Structure and Applications In terms of product structure, porous carbon for silicon-carbon can first be classified by raw-material type into biomass porous carbon, resin porous carbon, and pitch- or coal-based porous carbon. Biomass porous carbon is derived from renewable feedstocks such as coconut shells, bamboo, rice husks, sawdust, and starch. It offers broad raw-material availability, relatively low cost, and flexible supply responsiveness, making it suitable for cost-sensitive and rapidly iterating market requirements. Resin porous carbon is typically produced from phenolic resin or similar precursors. It benefits from mature processing technologies, controllable chemical structures, good pore uniformity, and strong batch consistency. This route offers clear advantages in high-performance anode systems, although its cost remains relatively high. Pitch porous carbon is produced from petroleum coke, coal-based materials, or related carbon sources. It provides a balance between cost, structural strength, and scalability, making it one of the most promising routes for future market growth. Based on the 2025 market structure, these three technology routes are developing in parallel, while pitch-based and high-pore-volume routes are receiving increasing market attention. By activation process, the market can be divided into steam activation and alkali activation. Steam activation is a mature process with a relatively lower environmental burden and is suitable for large-scale continuous production. Alkali activation is more effective in achieving high specific surface area and highly developed pore structures; however, it requires stricter management of washing, purification, residue handling, and environmental treatment. By pore volume, products can be divided into products with pore volume of ≤1.0 cm³/g and products with pore volume of >1.0 cm³/g. By specific surface area, products can be classified as ≥2,000 m²/g or <2,000 m²/g. High-pore-volume and high-specific-surface-area products are generally more beneficial for increasing silicon loading and ion-diffusion efficiency. However, they must also balance compacted density, structural strength, side reactions, and initial efficiency. In application terms, power batteries remain the absolute core demand segment. Consumer electronics and other applications remain smaller in scale but demonstrate stronger growth potential in premium niche scenarios. Regional Landscape and Market Opportunities From a regional perspective, China has become the most important global production and application center for porous carbon for silicon-carbon. According to QYResearch research, China accounted for approximately 94.76% of global capacity in 2025, while Japan accounted for approximately 5.24%. By 2026, China’s share is expected to increase further to approximately 97.87%, while Japan’s share is expected to decline to approximately 2.06%. By 2032, China is expected to remain dominant, accounting for approximately 97.26% of global capacity. Japan is projected to account for approximately 2.15%, while the rest of the world is expected to represent approximately 0.60%. This regional structure reflects China’s relatively complete industry-chain coordination capabilities across power batteries, silicon-carbon anodes, carbon-material processing, equipment manufacturing, and customer validation. Future market opportunities are expected to be concentrated in three key areas. First, growing demand from new energy vehicles and high-end power batteries for higher-energy-density anode materials will support the volume expansion of silicon-carbon anodes and directly stimulate demand for porous carbon. Second, increasing requirements from leading battery companies for low-expansion, long-cycle, and fast-charging silicon-carbon materials will promote the upgrade of porous carbon toward higher pore volume, higher specific surface area, and stronger consistency. Third, while consumer electronics and wearable devices currently have a smaller market base, they are highly sensitive to lightweight design, high-rate capability, and energy density. This creates differentiated growth opportunities for porous carbon materials. Overall, regional competition is shifting from simple capacity expansion toward comprehensive competition based on customer qualification, process compatibility, product stability, and cost optimization. Industry Chain and Future Outlook The upstream industry chain for porous carbon for silicon-carbon primarily includes biomass feedstocks such as coconut shells, bamboo, rice husks, sawdust, and starch; resin precursors such as phenolic resin; pitch-based feedstocks including petroleum coke and coal-based materials; and auxiliary materials such as steam, alkali activation agents, inert gases, cleaning agents, and purified water. The industry chain also involves core production equipment, including carbonization furnaces, activation furnaces, grinding and classification systems, washing and drying systems, and surface-modification equipment. The midstream segment covers porous carbon production and quality control, with core processes including precursor pretreatment, carbonization, activation and pore formation, ash and metallic impurity control, particle-size adjustment, pore-structure design, surface functional-group regulation, and consistency management. Downstream customers mainly include silicon-carbon anode material companies, anode manufacturers, battery-material companies, and battery-cell manufacturers. End-use applications include new energy vehicle power batteries, energy-storage batteries, premium consumer electronics batteries, and other high-performance lithium-ion battery applications. From the perspective of value distribution across the industry chain, the principal barriers are concentrated in pore-structure design, activation and pore-forming processes, purification and impurity control, batch consistency, and compatibility with downstream silicon-carbon systems. Porous carbon is not a standardized activated-carbon product. Its value in silicon-carbon anodes lies in balancing silicon-loading capacity, low expansion, structural strength, conductive pathways, and cycle stability, which requires a significantly higher level of material design and process control. Future industry-chain evolution is expected to include further upstream expansion by anode-material companies, stronger joint development between carbon-material suppliers and downstream customers, and differentiated competition among biomass-based, resin-based, and pitch-based routes across varying cost and performance ranges. From the perspectives of the policy environment, industry barriers, and market challenges, key hurdles in the porous carbon for silicon-carbon industry include high-temperature activation process control, pore-volume and specific-surface-area adjustment, ash and metallic impurity management, stable mass-production capability, customer validation cycles, and environmental and safety treatment. For downstream power-battery customers, consistency, swelling rate, initial efficiency, cycle life, and rate performance are all critical evaluation indicators. A single outstanding performance metric is insufficient to establish sustainable competitiveness. In addition, the cost of alkali-activation washing and wastewater treatment, the relatively high raw-material cost of resin-based routes, and the need for further optimization of high-end pitch-based routes represent practical industry challenges. Looking ahead, the porous carbon for silicon-carbon market is expected to continue evolving toward higher pore volume, higher specific surface area, lower impurity content, stronger consistency, lower cost, and improved downstream compatibility. Power batteries will remain the primary growth engine, while consumer electronics and other high-performance small-battery applications will provide supplementary growth. As silicon-carbon anodes continue to penetrate mainstream battery systems, porous carbon is expected to evolve from a supporting material into a critical base material that defines the performance boundary of silicon-carbon anodes. Companies with advantages in precursor resources, pore-forming technology, customer co-development, and large-scale manufacturing are expected to achieve larger market shares and more stable profitability during the next stage of industry expansion.
