Argonne developed a breakthrough cathode additive technology that compensates for initial lithium loss during SEI layer formation, paving the way for next-generation, high-energy-density batteries.
Argonne’s Gradient Cathode Technology was the recipient of a 2025 R&D 100 Award. The unique design combines a compositional and structural gradient into a “dual-gradient” particle, leading to improved stability at high voltages.
In a study published in Nature Energy, researchers demonstrated nickel-rich cathode compositions for rechargeable batteries that are free of the costly element cobalt.
