OQ Chemicals Introduces Innovative Oxvolt S221 for Battery Production

OQ Chemicals Unveils Oxvolt S221 for Superior Battery Manufacturing

OQ Chemicals has launched Oxvolt S221, an innovative co-solvent designed to revolutionize the production of lithium-ion batteries. This water-based electrode coating not only prevents cracking during the coating and drying phases but also meets the growing demand for high-performance and durable batteries in the e-mobility sector.

Benefits of Oxvolt S221 in Lithium-Ion Batteries

Ideal for high-energy graphite anodes, Oxvolt S221 has already received approval from various battery cell manufacturers. It plays a vital role as a film-forming and coalescing agent, ensuring a consistent and uniform coating on the graphite anodes. This improvement enhances electrode processing, resulting in fewer production failures compared to traditional water-based manufacturing methods.

Enhanced Slurry Processing

One of the remarkable properties of Oxvolt S221 is its ability to reduce slurry viscosity. By optimizing the mixing characteristics of the slurry, it improves electrode quality during and after the coating and initial drying processes. Unlike standard solvents, Oxvolt S221 is biodegradable and non-toxic, providing an eco-friendly alternative while maintaining efficiency. Added into the water as a minor co-solvent, it evaporates completely during drying, ensuring a clean final product.

Successful Pilot Tests with Oxvolt S221

In a pilot test conducted at CustomCells, Oxvolt S221 demonstrated significant advantages in the production of water-based graphite anodes. Dr. Claudia Fischer, Director of Global Business Development at OQ Chemicals, noted that there were no adverse effects on the battery cells' electrical properties or longevity. After extensive testing involving the C-rate and 300 charge cycles, performance levels remained consistent with those produced using conventional methods.

Promising Results for LFP Cathodes

Beyond graphite anodes, Oxvolt S221 has shown promising results when utilized as a co-solvent for LFP cathodes. This technology not only enhances processability but also underpins the development of high-performance, eco-friendly batteries designed for electric vehicles, emphasizing OQ Chemicals' commitment to sustainability.

Commitment to Supply Chain and Sustainability

Manufactured in the USA, Oxvolt S221 strengthens the supply chain for western industrial customers and aligns with the Inflation Reduction Act's requirements for US-based customers. OQ Chemicals actively supports the EU Battery Passport initiative, which aims to enhance the transparency of chemical usage in batteries and promote a more circular economy.
