Li-ion Identification For the Next Generation of Cathode Recycling

OnTo’s end-to-end solution will demonstrate (in partnership/collaboration with relevant industries) collection of lithium-ion batteries through recycling of cathode material. The DISCC project will prototype 1) deactivation of batteries 2) identification 3) sorting using automated techniques, 4) cutting with waterjet technology and 5) Cathode-Healing™ to produce valuable cathodes from scrap batteries.

Transition Metal Oxide Powders Made from Flame Spray Pyrolysis for Li-Ion Batteries

In 2012 the U.S. Department of Energy introduced its EV Everywhere Grand Challenge, with a stated goal of enabling “plug-in electric vehicles (PEVs) that are as affordable and convenient for the American family as gasoline-powered vehicles by 2022.” This requires a reduction in battery costs from the current $500/kWh to around $125/kWh. Most approaches have been to eliminate vehicle weight through lightweighting and to improve the energy density of battery materials. But what if we were able to just make the materials cheaper instead? To this end we introduce a green, low-cost method of producing cathode materials using an integrated flame spray pyrolysis process.

Moving Beyond 4-Hour Li-Ion Batteries: Challenges and Opportunities for Long(er)-Duration Energy Storage

This report is a continuation of the Storage Futures Study and explores the factors driving the transition from recent storage deployments with four or fewer hours to deployments of storage with greater than four hours. The report specifically builds on the first publication in the Storage Futures Study series, The Four Phases of Storage Deployment: A Framework for the Expanding Role of Storage in the U.S. Power System, that established a conceptual framework of roles and opportunities for new, cost-competitive stationary energy storage over the course of four phases of current and potential future storage deployment. This latest publication delves into Phases 2 and 3 when solar photovoltaics and storage increase the value of each other, and lower costs and technology improvements enable storage to be cost-competitive while serving longer-duration applications.
