The problem is well-documented: silicon expands during cycling, fractures mechanically, loses conductivity, and fades fast. Solving that means controlling surface chemistry at the particle level. UCT silanes are doing exactly that in next-generation EV battery development. ![600 x 308 CD Blog UCT - UCT Silanes in Action](https://blog.chromatographydirect.com/hs-fs/hubfs/Canva%20images/600%20x%20308%20CD%20Blog%20UCT%20-%20UCT%20Silanes%20in%20Action.png?width=600&height=310&name=600%20x%20308%20CD%20Blog%20UCT%20-%20UCT%20Silanes%20in%20Action.png) ## The Technology OneD Battery Sciences (OneD Material LLC) developed SINANODE® technology, integrating silicon nanowires into EV-grade graphite anodes. To stabilise these anodes and monitor their behaviour precisely, OneD incorporated dual reference electrodes into test pouch cells, enabling direct measurement of both anode and cathode potentials rather than just total cell voltage. This prevents potential drift during formation and cycling. But the real stability gains come from surface treatment. ## Where UCT Silanes Deliver Silicon composite anodes are highly moisture-sensitive. Moisture degrades performance and shortens cycle life. OneD addressed this using UCT's **(tridecafluoro-1,1,2,2-tetrahydrooctyl) trichlorosilane (T2492)** to create hydrophobic surfaces on silicon-containing particles. The result: a moisture-resistant coating that protects the anode during electrode processing and improves long-term stability. Beyond moisture resistance, functional silanes tailor particle surface chemistry to control interactions with binders, electrolytes, and other electrode components. Better surface interactions mean better electrode uniformity and better performance. OneD's patent lists **64 UCT silane products** applicable to achieving specific surface properties, demonstrating the breadth of what's possible with the right chemistry. ## The Results The patent reports enhanced capacity retention over extended cycling, reduced reference-electrode potential drift, and more stable silicon-containing anodes. As silicon nanowire and thin-film deposition techniques advance, UCT silanes remain an enabling technology for next-generation lithium-ion batteries. ## Why Chromatography Direct We're so much more than chromatography.
