Technical partner for Brazilian companies advancing critical minerals into qualified, battery-grade materials. From technical consulting and material validation to strategic R&D partnerships — bringing international battery materials expertise to local development.
Critical minerals only become valuable when they meet the strict purity, particle, and electrochemical specifications of battery manufacturers. We support partners through every TRL — from early characterization to customer qualification — aligned with the technology readiness levels required by major innovation grants.
Mineral characterization, impurity profiling, and feasibility for battery applications.
Purification, particle engineering, and chemical refinement to remove impurities.
Material meeting industry purity, density, and morphology specifications.
Electrochemical testing in coin and pouch cells; capacity, cycling, rate performance.
Protocol design and qualification strategy aligned with battery-grade specifications and customer requirements.
Layered oxides, polyanionic frameworks, and high-nickel chemistries — designed, prepared, and characterized at laboratory scale.
Hydrometallurgical and thermal routes for upgrading natural graphite to battery-grade specifications, with rigorous impurity control.
Si–C composite anodes for high-capacity applications. Particle engineering, surface coatings, and cycle-life optimization.
Particle shaping for tap density and rate performance. Material development and characterization from flake feed toward battery-grade specifications.
Galvanostatic cycling, EIS, CV, rate capability, and full electrochemical profiling from coin cells to pouch formats.
Biomass-derived hard carbon precursors for sodium-ion battery anodes. Leveraging Brazil's rich biogenic carbon sources to support the next wave of cost-effective, sustainable energy storage.
Beyond lithium-ion: sodium-ion, solid-state interfaces, alternative cathode formulations. Research-driven development for the next decade of energy storage.
Development of battery-grade materials, components, and intermediate products — spheroidized graphite, silicon-carbon composites, high-nickel cathodes, and lithium compounds.
Recovery of strategic metals from spent batteries and electronic waste. Characterization, hydrometallurgy, and re-qualification to battery-grade specs.
Supporting feedstock qualification, process-waste characterization, and downstream valorization of low-grade or marginal ore streams.
Low-carbon metallurgical routes, biomass-reduction processes, and alternative synthesis pathways for strategic metals — including biomass-to-anode graphite conversion.
Whether the goal is industrial adoption, customer qualification, or successful innovation funding — the same fundamentals matter. We help partners address the dimensions that determine technical and commercial outcomes.
Critical minerals are concentrated in a few countries — but the value of those minerals is captured wherever they are refined, qualified, and integrated into batteries. Nations that control only the upstream end remain exporters of low-value raw material; those that climb the chain build industrial capability, attract capital, and secure their place in the global energy transition.
Demand is accelerating — fast. Global EV sales are expected to surpass 50% of new vehicles by 2035, with countries like the UK, Canada, and major European economies legislating 100% zero-emission targets. Stationary storage is scaling alongside renewable generation. Decarbonization commitments and energy security policies are reshaping where battery materials will be sourced, processed, and qualified for the next two decades.
Yvinox operates between two complementary regions: a resource-rich south with vast graphite, lithium, nickel, and manganese reserves, and a technically mature north with the testing, validation, and qualification infrastructure that battery manufacturers require. Bridging the two is how raw mineral becomes strategic asset — and how national projects earn their place in global value chains.
Every recommendation is anchored in measured electrochemical data. We tell partners what the cells say — not what is convenient to hear.
A material that performs in a coin cell is a beginning, not an answer. Real value lives in scalable, reproducible, manufacturable processes.
Engagements run in English and Portuguese, with cultural fluency in research and applied technical contexts across Brazil and North America.
The earlier we engage, the more we can shape the technical approach and strategic direction. Whether you are evaluating feedstock, qualifying a battery-grade material, scoping an R&D collaboration, or assembling an innovation proposal — reach out.
