Hide and seek between atoms: Findings illuminate mechanism of high-nickel cathodes for lithium-ion batteries

Researchers have developed a method to understand and stabilize high-nickel cathode materials in lithium-ion batteries, crucial for electric vehicles. By using deep learning and advanced microscopy, they analyzed cation mixing, which affects battery performance. They found that doping with metals like aluminum, titanium, and zirconium enhances structural stability and performance. Titanium was the most effective, improving discharge capacity and retention. This research provides insights into optimizing high-capacity cathode materials for better battery performance.
