Design combines the best aspects of different compositions and structures into individual cathode particles
BY MICHAEL MATZ |OCTOBER 29, 2024
A breakthrough dual-gradient design for the batterys cathode substantially increases energy storage capacity, stability and lifetime while reducing costs. It could accelerate widespread adoption of electric vehicles and grid batteries.
The U.S. Department of Energys (DOE) Argonne National Laboratory has developed a new design that dramatically improves the performance and reduces the costs of lithium-ion batteries.
The design is likely to accelerate adoption of electric vehicles (EVs) and grid energy storage, facilitating global decarbonization efforts. It continues Argonnes decades-long history of leadership and innovation in battery research.
The dual-gradient particles were much more durable than the original Argonne design. After charging and discharging the material 500 times, it lost only about 2% of its storage capacity. Based on this finding, the team expects that the material can support a much longer battery lifetime.

❝This breakthrough material represents an across-the-board improvement for batteries. It features higher storage capacity, robust stability and heat tolerance at high voltages, and longer lifetimes. Its high energy density enables production of smaller, lower-cost batteries, supporting widespread adoption of EVs and grid batteries.❞ Khalil Amine, Argonne Distinguished Fellow and leader of Argonnes Advanced Battery Technology team

This breakthrough material represents an across-the-board improvement for batteries, said Amine. It features higher storage capacity, robust stability and heat tolerance at high voltages, and longer lifetimes. Its high energy density enables production of smaller, lower-cost batteries, supporting widespread adoption of EVs and grid batteries. Our patented design and fabrication process is ready to be licensed by industry.
