Fast-Charging, Wide-Temperature, Low-Cost, Durable Batteries Enabled by Cobalt- and Nickel-Free Cathodes and Cell Engineering
Virginia Polytechnic Institute and State University (Virginia Tech) will develop fundamentally disruptive electric vehicle (EV) batteries that combine cobalt- and nickel-free cathodes, electrolytes that enable fast-charging and all-weather operation, and coal-derived, high-capacity anodes. The Virginia Tech team will use theoretical modeling and advanced materials and cell characterization techniques to guide the system-level integration of battery components. The synergistic integration of these novel materials and chemistries into batteries, together with techno-economic and environmental impact analyses, offer the potential to improve the affordability, convenience, reliability, and safety of EVs. The technology’s reliance on earth-abundant and low-cost raw materials significantly mitigates supply chain risks while cathode cost will be reduced by excluding cobalt and nickel. Finally, using a coal/carbon/silicon anode will partially alleviate environmental issues of coal waste and can reduce anode cost compared with a conventional graphite anode.
