OCSiAI Announces New Generation High Solid Content Conductive Agent Product Now Available in the Chinese Market, with Plans to Expand to the European Market. Following OCSiAl's technological advancements, which have increased the production capacity of single-walled carbon nanotube powder, the new high solid content conductive agent offers a solid content increase of over 2 times compared to existing products, further reducing the cost of using single-walled carbon nanotubes and improving overall value.
By expanding the production capacity of single-walled carbon nanotube synthesis facilities, TUBALL BATT products achieve enhanced cost-effectiveness, further solidifying OCSiAl's leading position in the global single-walled carbon nanotube market. Furthermore, compared to existing solutions, the new generation conductive agent slurry boasts a 2.5-fold increase in single-walled carbon nanotube content, which helps further reduce the cost of lithium-ion battery products and improve the economic viability for Chinese battery manufacturers using high-quality single-walled carbon nanotubes sourced from Europe.
OCSiAl also provides high solids solutions. Compared to traditional conductive agents, such as multi-walled carbon nanotubes and carbon black, TUBALL BATT offers a higher cost-effectiveness ratio. Compared to multi-walled carbon nanotubes, single-walled carbon nanotubes require only 1/10 of the amount.

Effectively assists lithium-ion battery manufacturers in enhancing product performance.。The main advantage of the new conductive liquid product is its high concentration of single-walled carbon nanotubes.，Superior to current products2–2.5Multiply。
OCSiAl's Energy Project Leader and Senior Vice President, Andrej Seniut, explained: "The incorporation of single-walled carbon nanotubes into all series of single-walled carbon nanotube-based dispersions represents an industry-leading level of performance. Adding the same amount of single-walled carbon nanotubes to the battery electrode, now requires less solvent, enabling battery manufacturers to achieve higher solid content in their slurry. Furthermore, the high-solid dispersion is undoubtedly more cost-effective compared to existing products, significantly improving value for money."
In the manufacturing, transportation, storage, and battery production processes involving dispersed liquid materials, the reduction in material consumption leads to a corresponding decrease of 2-2.5 times in logistics costs, which promotes the sustainable development of the industry.
"Andrej Seniut added: "This new product can reduce the cost of using single-walled carbon nanotubes in the lithium-ion battery industry. In the future, next-generation lithium-ion battery products will offer significant cost advantages compared to using multi-walled carbon nanotubes or other single-walled carbon nanotube-based solutions currently available in the Chinese market, in addition to numerous performance advantages."
Currently, these two new products are being manufactured locally in China. In addition, the new OCSiAl factory located in Belgrade, Serbia, is also in the planning stages for producing new dispersion products.
OCSiAl manufactures high-quality single-walled carbon nanotubes under the TUBALL brand. Currently, TUBALL single-walled carbon nanotubes exhibit superior performance compared to other single-walled carbon nanotubes available in the Chinese market. The TUBALL single-walled carbon nanotubes have the following characteristics: diameter of 1.6(±0.4)nm; length exceeding 5μm and length-to-diameter ratio exceeding 3000.
OCSiAl provides high-quality single-walled carbon nanotubes with a carbon nanotube content exceeding 99%. The G/D ratio is an important indicator for assessing the quality and defect level of single-walled carbon nanotubes. Therefore, TUBALL single-walled carbon nanotubes are considered high-quality products.
OCSiAI's single-walled carbon nanotubes possess unique morphological, physical, and mechanical properties, including high length-to-diameter ratio and flexibility, making them ideal high-performance conductive and reinforcing materials. Unlike short and rigid multi-walled carbon nanotubes, single-walled carbon nanotubes establish robust, long-range conductive networks between active material particles, improving key battery characteristics such as enhanced cycle life, reduced DCR (DC resistance), improved rate performance, and internal cohesion between active materials. This is particularly important for systems with high volume expansion, such as silicon-based anodes, where OCSIAI's single-walled carbon nanotubes can significantly mitigate degradation issues, effectively facilitating the industrial application of silicon as a high-capacity anode material. Thanks to TUBALL single-walled carbon nanotubes, silicon-oxygen anodes can now explore up to 90% silicon content, enabling the industrialization of batteries with energy densities of up to 360 kWh/kg, and even higher breakthroughs.
In the positive electrode, a robust TUBALL single-walled carbon nanotube network can be achieved by: increasing the internal cohesion – strengthening the bonding between active material particles – which is currently widely used in thick coating systems.
In future thick coating systems, this product will contribute to the flexibility and stability of both ternary and iron phosphate thick electrodes.
OCSiAl headquarters is located in Luxembourg and has been deeply involved in the Chinese lithium-ion battery market for 8 years. In 2019, leading Chinese chemical manufacturers, Shenyang Huiting Nanotechnology Co., Ltd. (Huiting) and Shanghai Haiyi Trading Co., Ltd. (Haiyi), launched the large-scale production of TUBALL BATT, a dispersion liquid for single-walled carbon nanotubes for lithium-ion batteries, in China, aiming to enhance the resilience of the supply chain for single-walled carbon nanotube solutions in the Chinese market. Both companies are also committed to continuously expanding their production capacity to meet the growing market demand. Currently, both domestic manufacturers have increased their production capacity, and the combined annual production capacity of TUBALL BATT for lithium-ion batteries will reach 40,000 tons in 2023-2024.
