University of Waterloo researchers have achieved a breakthrough in electric vehicle (EV) battery technology that addresses key barriers to EV adoption including charging time and longevity.
Developed by Waterloo Engineering professors Dr. Yverick Rangom and Dr. Michael Pope, both from the Department of Chemical Engineering, their innovation enables EV batteries to charge from zero to 80 percent in just 15 minutes instead of the usual one hour, and withstand up to 800 charging cycles.
The research focuses on re-engineering the anode, a key battery component traditionally made of graphite. The team developed a novel method to fuse graphite particles, improving electrical conductivity and enabling faster lithium-ion movement without compromising battery safety or longevity. This design is compatible with existing lithium-ion battery manufacturing processes, ensuring affordability and scalability for industry adoption.
“This innovation has the potential to make EVs more accessible to a wider audience,” said Rangom. “By enabling faster charging, smaller battery sizes, and longer lifespans, we can reduce costs and address concerns like range anxiety and the reliability of second-hand EVs.”
The technology could transform EV ownership for urban residents without home charging capabilities and improve the market for used EVs by enhancing battery durability. Pope emphasized the design’s practicality, stating, “We’re not reinventing the wheel. We’re using existing materials but rearranging them in smarter ways to deliver better performance at a lower cost.”
Next steps include optimizing manufacturing processes and testing prototypes to ensure industry readiness. The team is actively engaging stakeholders to bring this transformative solution to market.
