Researchers at the University of Auckland have developed a new battery material that could significantly improve electric vehicle (EV) performance by increasing range on a single charge and extending battery lifespan.
The innovation focuses on high-entropy oxide battery materials, which combine multiple metal elements into a single, stable structure capable of storing lithium more efficiently than conventional materials.
Using a “bottom-up” synthesis method, the team combined five metals and subjected them to calcination, producing a new anode material—the part of the battery where lithium is stored that can hold more energy while maintaining performance over numerous charging cycles.
If successful, the material could replace graphite, the standard anode in lithium-ion batteries, which are central to EVs and energy storage systems. Improvements in battery technology could also support broader carbon-neutral and clean energy initiatives.
The research team includes scientists with expertise in chemical and materials engineering, and the technology is being prepared for commercialization through a joint venture supported by academic and private investors.
This development marks a promising step toward more efficient, longer-lasting batteries for electric vehicles and renewable energy storage.
