Chicago-based Volexion has started commercial shipments of its graphene-coated cathode active materials to leading battery manufacturers around the world. The shipments mark a critical step forward for the company as it transitions from R&D into real-world deployment. Early recipients include top-tier automotive OEMs, international cell manufacturers, and U.S.-based energy storage developers, with more shipments already in progress.
The materials address a key issue in lithium-ion battery performance: cathode degradation caused by repeated cycling and structural stress. By applying a thin, protective graphene layer to cathode particles, Volexion aims to enhance cycle life, improve energy density, and reduce degradation without requiring changes to existing production infrastructure.
Rather than developing new chemistries, the company’s technology enhances existing platforms by extending their useful life and improving performance.
According to CEO Joseph Adiletta, “Every lithium‑ion battery is fighting a slow battle against its own chemistry; cathode materials wear down as they work. Our graphene coating shields those materials from that breakdown. It’s a drop‑in solution that extends life, boosts performance, and enables next‑generation chemistries without costly retooling.”
The coatings can be applied using widely available equipment, allowing quicker adoption across different parts of the battery supply chain.
Volexion’s graphene solution supports a wide range of cathode chemistries, and this versatility makes it well-positioned to serve multiple market segments, from electric vehicles to consumer electronics and grid-scale storage.
As part of its go-to-market strategy, Volexion is working directly with manufacturers to integrate the graphene coating into their existing processes. Close to a dozen companies—including materials suppliers, battery developers, and OEMs—are currently evaluating the technology across diverse applications. The approach reflects growing industry interest in scalable solutions that enhance current lithium-ion platforms rather than replace them entirely.
Volexion expects to scale production volumes over the next several years, aligned with individual customer roadmaps and product cycles.
President and COO Damien Despinoy framed this milestone as a pivotal step in the company’s broader commercialization efforts. “Our customers’ increasing demand for scalable solutions for current and next-generation battery problems has driven deliveries across geographies, chemistries, and applications. This is just the beginning — and, with an easily scaled solution, we are ready to go.”
Future growth will likely focus on supporting high-demand applications such as EVs, drones, grid storage, and defense technologies. The next test will be whether the technology can scale efficiently while delivering on promised gains in real-world conditions.
Backed by Clean Energy Ventures and Earth Foundry, and built on research from Northwestern University and Argonne National Laboratory, Volexion is pursuing a pragmatic commercialization path. Its focus on performance improvements—rather than complete platform overhauls—could offer a more capital-efficient way to support the battery industry's shift toward high-performance, longer-lasting systems.
