"Next-Generation Tin-Based Metal Alloy Anodes for Li-ion Batteries: Safer, Thinner, and Cleaner Energy Storage"
Current industrial anode technologies — predominantly graphite and silicon-carbon based systems—are increasingly limited by structural, electrochemical, and environmental constraints. Powder-based architectures require binders and solvents, thick electrode coatings (100–250 μm) for high energy application, and energy intense drying/calendering steps, resulting in suboptimal gravimetric and volumetric energy density, poor thermal/electrical conductivity and limited recyclability.
ONLi presents a next-generation anode platform based on a proprietary, non-powder, ultra-thin (6–20 μm) metal alloy architecture, formed directly on copper via a binder-free, solvent-free deposition process. The resulting anode layer exhibits high adhesion through diffusion bonding and delivers electrical and thermal conductivity several orders of magnitude greater than conventional systems. At the active material level, ONLi achieves up to 1.8× gravimetric and 8× volumetric energy density compared to graphite, while operating without lithium metal plating risk under fast charging (2C -3C) conditions.
The technology is fully compatible with roll-to-roll (R2R) manufacturing lines and designed for cleanroom-free production. Extensive materials science development, including thermal stability, electrochemical cycling, and interface analysis, has validated ONLi’s performance and safety profile. A comprehensive techno-risk analysis confirms the maturity of the platform for pilot-line prototyping. The ferromagnetic nature of the ONLi alloy anode enables straightforward magnetic separation during end-of-life processing, significantly simplifying recycling and enhancing material recovery compared to conventional non-magnetic electrode systems.
Market entry will initially target compact, high-performance applications such as e-motorcycles and light mobility systems, where thermal management, form factor, and energy density are critical. ONLi’s superior thermal conductivity significantly enhances heat dissipation, extending cell lifetime and improving safety margins in densely packaged systems.
Ongoing work includes industrial scaling via modular production units, and extending the architecture to Na-ion chemistries via an alloy oxide-based cathode concept—paving the way for a full-cell ONLi ecosystem. With demonstrated manufacturability and a strong roadmap toward TRL7, ONLi offers a disruptive and sustainable alternative to legacy anode technologies in the evolving battery value chain.
