Caporus’ patented capacitor technologies enable reliable capacitive energy storage and filtering at the higher voltages and temperatures required by the next generation of high density power conversion systems. Caporus dielectrics employ Nanoscale Lamellar Porosity (NLP) to meet the increasingly demanding requirements for power conversion systems that are key to supporting the electrification of transportation and integration of distributed energy resources on the grid. Caporus is expanding its operations beyond facilities at Argonne National Laboratory to add a pilot plant in the southwest suburbs of Chicago that will support scaling production of its dielectrics and capacitor products.
Conamix is commercializing new low-cost high-energy materials for the global lithium ion battery market. The company’s materials are designed to drop-in to existing manufacturing infrastructure to both improve the energy density and lower the cost of lithium ion systems. Founded in 2014, the company is led by an experienced team of chemical and battery industry leaders and has intellectual property agreements with multiple leading global research institutions.

CorePower is driving magnetification by redefining the limits of magnetic solutions for EVs and the grid. The combination of advanced manufacturing processes and novel materials represents a long-awaited and significant advancement in efficiency and power density in power electronics and power conversion systems and has the potential to reduce the need for rare earth elements in electric motors.
Divigas has invented a new polymeric membrane (Divi-H), which can purify hydrogen up to a level of 99.95% purity from any feedstock composition, with best in class recovery rate, and is robust even under the most adverse feed conditions. Divi-H can be used in a wide range of applications, from fuel gas recovery to loop optimization through H2/CO adjustment and carbon capture, and can operate in refineries, petrochemical plants, ammonia plants, methanol production, metallurgical production, power-to-gas systems, gasifiers and many other locations.
Echion Technologies (Cambridge, UK) supplies its world-leading Niobium-based anode material, XNO®, to cell manufacturers looking to build lithium-ion batteries with market-leading safety, cycle-life, and fast-charging capabilities. XNO® enables batteries to fast charge safely in less than 10 minutes, with high energy density and a cycle life of more than 10,000 cycles.
XNO® materials are based on proprietary mixed Niobium oxide compositions and microparticle designs protected by 13 international patent families and are now being scaled-up to the multi-thousand tonne/year production scale. The differentiated technology helps cell manufacturers gain a technical and commercial advantage in high-value, fast-growing markets where end-users require the safety, low total cost of ownership, and unique performance mix offered by XNO®.
This includes industrial and commercial e-mobility markets: rail, marine, AGVs, mining trucks and other off-highway vehicles, opportunity-charging e-buses and other high-utilisation EV fleets. XNO® also provides a unique value proposition for the micro-battery market and specific applications for the ESS, motorsports, and medical markets.
Energy Vault creates renewable energy storage solutions designed to advance the global transition to a carbon free, resilient power grid and transform the world’s approach to utility scale energy storage. At Energy Vault, we work to combat climate change by enabling clean and reliable electricity through innovation in renewable energy storage. Utilizing a unique approach to the circular economy that integrates energy waste for beneficial reuse at unprecedented economics, Energy Vault innovates to accelerate the shift to a fully renewable world.
FluoRok (Oxford, UK) is reinventing fluorochemicals manufacturing and the way the world accesses fluorinated products such as Li-ion battery electrolyte salts and additives. FluoRok’s proprietary process bypasses for the first time the energy intensive intermediary hydrofluoric acid (HF), one of the most hazardous and difficult-to-handle chemicals on the planet. FluoRok’s solutions are safer, more sustainable, lower cost, and introduce for the first time the circular economy in fluorochemical manufacturing. Spun-out of the University of Oxford, UK in 2022, the team has decades of combined experience in fluorine chemistry and business development and is currently working towards their first pilot plant.
Iontra Inc, a Denver-based battery performance and safety technology company, has been in stealth mode for nearly a decade and is partnered with various OEMs to commercialize its breakthrough charging technology that will replace incumbent CC/CV charging and drastically reduce the development time of new batteries and battery-powered products. Iontra has found a fundamental way to materially reduce degradation in lithium batteries when charging or discharging, opening the door to more than two-fold improvements in charging speed and cycle life, improved capacity utilization, and safe cold-temperature charging.
Natron Energy’s mission is to transform industrial and grid energy storage markets by providing customers with lower cost, longer lasting, more efficient, safer batteries.
