Utah's halloysite clay deposits hold a domestic answer to the EV battery anode problem — nano-silicon from a natural nanostructured mineral, no complex synthesis required.

Summary
Provo-based Ionic Mineral Technologies turns naturally tubular halloysite clay into nano-silicon battery-anode material. Its Utah ore could be a genuine cost advantage, while alumina and critical-metal co-products hedge the economics if battery-grade silicon alone cannot carry the operation.
Impact
The graphite anode in virtually every lithium-ion battery today is sourced predominantly from China. Silicon has roughly 8x the theoretical charge-storage capacity of graphite and would enable longer-range EVs, faster charging, and smaller or lighter batteries across every application. Ionic MT's Ionisil nano-silicon is positioned as a drop-in anode material that battery manufacturers can blend with graphite; at 15% silicon loading, the company claims doubling of anode capacity.
The supply chain impact case: if Ionic MT succeeds at scale, it shifts a piece of the EV battery supply chain from China-dependent graphite to a US-domestic silicon source. This is directly relevant to defense procurement priorities and domestic manufacturing policy objectives.
Three co-products from a single halloysite feedstock reduce the production economics risk: Ionisil nano-silicon (energy storage), IonAL high-purity alumina (battery separators, ceramics), and rare earth and critical technology metals recently discovered at Silicon Ridge.
What They Are Building
Ionic MT is building a vertically integrated operation spanning geology, mining, materials processing, and anode material supply. The technical work centers on converting raw halloysite clay into battery-grade nano-silicon through a process that leverages the mineral's natural tubular nanostructure rather than requiring synthetic nanoengineering. Scaling production from lab to 1,000+ metric tons annually while maintaining consistent anode-grade quality is the unsolved manufacturing problem the Series B is funding.
What They Need Now
Hiring centers on hydrometallurgy and separation-process chemical engineering (acid leaching, impurity removal, crystallization, solids handling for high-purity materials). Broader needs still include process engineers and electrochemists across mining-to-cell development, plus supply-chain and business-development people who understand automotive and defense procurement qualification cycles.
Who Could Help
Battery cell OEM qualification engineers who can run Ionisil against graphite benchmarks in real cell formats; automotive supply chain procurement contacts who understand anode qualification timelines; DOE critical materials program managers; and investors experienced with mining-to-materials vertical integration.
Utah Context
Juab County, Utah holds Ionic MT's key mineral deposits — a geographic asset that no amount of capital can replicate elsewhere. The Provo headquarters places the company in Utah County's engineering and technology cluster, with access to Brigham Young University and regional manufacturing talent.
Utah's role in the critical minerals supply chain is growing: halloysite, lithium (from geothermal brines and hard rock deposits), and rare earth co-products from various mining operations collectively make Utah a potential node in domestic battery supply chains being reorganized in response to China trade policy.
