Xponential Battery Materials (XBM), operating as XBM USA LLC, is an advanced battery materials company based in Los Angeles, California. Established in 2020, XBM is dedicated to developing sustainable cathode materials for next-generation lithium-sulfur (Li-S) and solid-state batteries. The company’s core mission centers on creating high-capacity, low-carbon footprint battery materials to enable the widespread adoption of electric vehicle and aviation technologies manufactured in the USA.
XBM focuses on leveraging abundant industrial byproducts, such as sulfur from petroleum refining and lignin/tannin from the paper industry, to produce its materials. This approach aligns with circular economy principles by converting waste streams into valuable battery components. By doing so, XBM aims to reduce dependency on foreign critical minerals, lower manufacturing costs, and enhance the environmental profile of battery production within the United States. The company positions itself as a partner for battery developers, contributing to a more sustainable and domestically sourced battery future.
Battery Technology
Xponential Battery Materials specializes in the development of its proprietary CarbonX Lithium-Sulfur (Li-S) Battery Technology Platform. This platform incorporates innovative materials designed to improve the performance and sustainability of batteries. A central innovation is the CarbonX High Capacity Sulfur Cathode Active Material. This material is engineered to result in lighter, more powerful, safer, and less expensive batteries compared to traditional lithium-ion batteries.
The CarbonX cathode materials are derived from industrial byproducts like tannin, lignin, and sulfur, emphasizing a sustainable and domestic supply chain. The technology aims to provide a reliable, U.S.-sourced supply of critical battery materials. XBM’s materials are intended for integration into various applications, including electric aviation, electric vehicles, consumer electronics (3C devices), wearables, power tools, and the defense sector. The company’s focus extends to developing solutions for sodium-sulfur (Na-S) cathode materials and solid-state battery technologies, utilizing its sulfur-based cathode chemistries to support these emerging battery types.
Recent Projects
Xponential Battery Materials has actively pursued strategic collaborations to advance its technology. In a 2025 Memorandum of Understanding (MoU), XBM partnered with Ampcera to jointly develop sulfur solid-state batteries. This collaboration aims for high energy density, low weight, and cost-effectiveness for electric vehicle applications, combining Ampcera’s solid-state electrolyte innovations with XBM’s CarbonX cathode materials to facilitate commercial-scale U.S. production of Li-S and Na-S solid-state cells.
Separately, in 2025, XBM signed another MoU with International Battery Company (IBC). This agreement focuses on integrating and scaling CarbonX Li-S cathodes in commercial solid-state battery manufacturing to further strengthen U.S. domestic battery supply chains. In 2024, XBM expanded its biomass-based cathode material line by incorporating lignin byproducts from the U.S. paper industry, alongside its existing tannin-based carbon hosts, demonstrating comparable performance and enhancing feedstock diversity.
