Head of Marketing

About Coreshell: Coreshell is redefining what’s possible for electrification by tackling the true barrier to progress: batteries. From EVs to drones, humanoids, and delivery robots, performance and usefulness all hinge on power. Coreshell’s battery technology replaces graphite with abundant U.S.-sourced silicon, delivering ~30% more capacity, faster charging times, and cutting lifecycle emissions nearly 30%. Already gaining traction in EVs, the technology integrates with existing lithium-ion manufacturing, lowers costs by over 25%, and provides the only scalable, domestic alternative to foreign--controlled graphite. By extending range, runtime, safety, and affordability, Coreshell is enabling the future of electrification from electric vehicles and robotics to energy storage and beyond while anchoring sustainable electrification at scale.
