Core Viewpoint - Daoshi Technology is shifting its fundraising focus from a planned project for ternary precursor production to a new project for single-walled carbon nanotubes, indicating a strategic move to capture market share in this high-demand sector [3][5]. Fundraising and Project Details - The company has approved a change in the use of 300 million yuan of unallocated funds from the original plan for a 100,000-ton ternary precursor project to a new project for producing 120 tons of single-walled carbon nanotubes [3][4]. - The new project, managed by Jiangmen Haoxin New Energy Co., has a total investment of 600 million yuan and an estimated construction period of three years [4]. Market Dynamics and Demand - Single-walled carbon nanotubes (SWCNTs) are characterized by superior performance and higher technical barriers compared to multi-walled carbon nanotubes, with current supply unable to meet demand [5][6]. - The global market for SWCNTs is dominated by OCSiAl, which holds over 90% market share, while domestic players like Tianai Technology are also expanding production capabilities [5][9]. - The demand for SWCNTs is expected to rise significantly, particularly in the lithium battery sector, where their use as conductive agents is projected to grow from 18.4% in 2024 to over 20% in 2025 [5]. Production Capacity and Future Outlook - Daoshi Technology aims to achieve an annual production capacity of 50 tons by Q1 2026, with plans to reach 120 tons within the following year [5]. - Tianai Technology is also ramping up production, with a 450-ton project expected to begin operations in Q4 of this year [8][9]. - The overall market for SWCNTs is projected to grow from $1.37 billion in 2024 to $1.55 billion in 2025, reaching $3.63 billion by 2032, with a compound annual growth rate of 13.0% [18]. Technological Advancements - Daoshi Technology has reportedly overcome challenges in the low-cost, large-scale production of SWCNTs, positioning itself to meet the high-end market demands [5]. - Tianai Technology has developed continuous production techniques for SWCNTs, enabling it to supply high-quality products for various applications, including lithium-silicon batteries [9][12]. Applications and Industry Trends - The increasing demand for high-capacity and fast-charging lithium batteries is driving the need for SWCNTs, with projections indicating significant market growth in the cylindrical battery sector [12][13]. - The potential for SWCNTs extends beyond lithium batteries, with ongoing research into applications in lithium-sulfur and sodium-ion batteries, indicating a broadening market scope [15][18].
