OUR PORTFOLIO OF COMPANIES
Volta manages a portfolio of technology investments across technology categories and maturity stages to balance risk and maximize impact.
Ionic Materials is a materials technology company that enables next-generation solid-state batteries. Its breakthrough polymer is the first solid electrolyte to fully function at room temperature and be compatible with lithium and alkaline-based batteries, and enable new and advanced electrode chemistries to significantly improve battery safety, performance and cost. Developed by a world-class team of polymer scientists, Ionic Materials is headquartered in Woburn, MA.
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.
Solid Power is an industry-leading developer of all solid-state rechargeable batteries for electric vehicles and mobile power markets. Founded in 2012 as a spin-out from the University of Colorado Boulder, Solid Power replaces the flammable liquid electrolyte in a conventional lithium-ion battery with a proprietary sulfide solid electrolyte. As a result, Solid Power’s all solid-state batteries are safer and more stable across a broad temperature range, can provide a 50-100% increase in energy density compared to the best available rechargeable batteries, enable cheaper, more energy-dense battery pack designs and are compatible with traditional lithium-ion manufacturing processes. Solid Power has extensive partnerships with both BMW and Ford to jointly develop all solid-state batteries using the company’s Louisville-based megawatt-hour-scale (MWh) production line. In addition to Volta, Solid Power is backed by prominent investors including Samsung, Hyundai, Ford, and Solvay.
Nanoscale Components has developed a novel, cost-effective process to pre-lithiate lithium-ion battery electrodes. This process enables cell manufacturers to use high-specific capacity materials such as silicon to make cells with higher energy density and improve the cycle life of those materials.
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. Natron’s battery products are based on a unique Prussian blue chemistry and can integrate into a wide variety of energy storage applications ranging from critical backup power systems to EV fast charging and behind-the-meter applications. Natron’s batteries are UL1973 recognized and have passed rigorous UL9540A fire testing, offer higher power density, faster recharge and significantly longer cycle life than other energy storage technologies. Natron builds its batteries using commodity materials on existing cell manufacturing lines. Natron is backed by leading venture capital investors including ABB Technology Ventures, Chevron, Khosla Ventures, Nano Dimension, Prelude Ventures and Volta Energy Technologies.
