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.
OneD’s SINANODE™ technology platform fuses nano-silicon into commercial graphites – increasing the performance of EV batteries while lowering costs. Silicon nanowires provide 3,250 mA/g of reversible capacity and avoid the expansion and breakage issues of other solutions such as silicon oxide. The result is faster charging, longer range, and affordable EVs.
With over 240 patents, OneD Battery Sciences has joint development agreements with many industry partners including GM, which is also an investor.
Smart Wires develops and implements digital technologies that advance the delivery of affordable, clean electricity on grids around the world. Smart Wires’ technology quickly unlocks gigawatts of new capacity on the existing power grid by intelligently routing power to travel across underutilized power lines.
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.
