X-BATT launches Glassact silicon oxycarbide anode with 800 mAh/g target

By AI, Created 6:30 PM UTC, May 22, 2026, /AGP/ – X-BATT unveiled Glassact™, a domestically made silicon oxycarbide anode designed to deliver higher energy, faster charging and better stability than graphite. The company says the spherical material could help battery makers scale safer, higher-capacity lithium-ion cells for EVs, grid storage and other uses.

Why it matters: - X-BATT is targeting one of lithium-ion batteries’ biggest tradeoffs: higher energy density without the swelling and stability problems that have limited silicon-heavy anodes. - The company says Glassact™ could more than double graphite’s capacity while supporting safer, higher-energy cells for EVs, grid storage, defense and consumer electronics. - The material is designed and manufactured in the U.S., which could matter for domestic battery supply chain efforts.

What happened: - X-BATT unveiled Glassact™, a spherical silicon oxycarbide (SiOC) anode, on May 22, 2026, in Orlando, Florida. - The company says Glassact™ is a domestically manufactured anode powder engineered for scalable production. - X-BATT published performance targets upfront, including more than 800 mAh/g reversible capacity, more than 8C charge rates with more than 80% of nominal capacity retained, less than 8% cyclic swelling and more than 8,000 cycles at greater than 80% depth of discharge. - CEO Bill Easter said the material is meant to more than double the energy of graphite at a cost structure that scales.

The details: - X-BATT forms a proprietary pre-ceramic resin into nearly perfect microspheres with tightly controlled size distribution, then converts the spheres into ceramic at high yield. - The process reduces the costly back-end powder processing that competing materials often require. - Each sphere contains a conductive carbon scaffold, a glassy ceramic matrix tuned for lithium storage and a protective outer shell that helps keep the electrolyte stable. - The structure is made through low-temperature, short-residence pyrolysis furnaces. - X-BATT says the result is high capacity, high conductivity, fast charging and improved stability without the swelling associated with pure-silicon anodes. - SiOC is described as thermally and chemically stable and not prone to swelling during charging. - The spherical morphology and low surface area are intended to widen the safety margin. - X-BATT produces the spheres through a scalable emulsion process using feedstocks and equipment already proven in adjacent industries.

Between the lines: - X-BATT is leading with targets instead of broad performance claims, which signals an attempt to address skepticism in the battery materials market. - The company is framing Glassact™ as a manufacturing story as much as a chemistry story, with emphasis on domestic production, scalable equipment and fewer processing steps. - The pitch suggests X-BATT is aiming at battery makers that want silicon-like performance without the reliability penalties that have slowed adoption.

What’s next: - X-BATT is positioning Glassact™ for use in EVs, grid storage, defense and consumer electronics. - The company will need to prove the published targets in real cells and at production scale. - X-BATT says the production approach is built for scale, suggesting a future push toward commercial partnerships and qualification work.

The bottom line: - Glassact™ is X-BATT’s bet that a spherical ceramic silicon anode can deliver silicon-level gains with graphite-like practicality.
