About

About XBM USA LLC Founded in 2020 and over the past 5 years, Xponential Battery Materials (XBM USA) has been working to develop CarbonX™, a superior, sustainable lithium-sulfur (Li-S) Cathode Active Material (CAM). The company is working with US OEMs developing next-generation high-performance and low-weight eAreospace and EV battery applications. CarbonX pairs step-change performance with a fully domestic, low-risk supply chain, offering ~2× the cathode capacity vs today’s NMC or LFP cathodes at ~40–50% lower $/kWh, using abundant U.S. industrial byproducts, (sulfur from petroleum refining and tannin/lignin from paper and pulping), as core base materials that helps mitigate polysulfide shuttle, enabling stable high-capacity operation and longer cycle life. The result is a circular-economy CAM manufactured entirely in the United States and sourced across the Americas. CarbonX’s ~40% cathode savings can translate to up to ~25% reduction in total battery cell cost. XBM expects initial commercial deployments in eAreospace, EV and consumer battery markets.
