A novel mathematical framework unlocks unlimited customization of full concentration gradient in high-nickel cathodes for improved safety and stability
High-nickel cathodes are promising for improving the energy density of lithium-ion batteries (LIBs). However, their high nickel concentration leads to intense side reactions, degrading safety and stability. While full concentration gradient (FCG) design can address this issue, current approaches limit design flexibility.
Now, researchers have developed a novel mathematical framework that, combined with an automated reactor system, allows unlimited customization of FCGs with independent parameter control, leading to LIBs with enhanced safety and stability.
With the recent global push toward renewable energy and electric vehicles, the demand for lithium-ion batteries (LIBs) is rising rapidly. The performance and stability of LIBs largely depend on the cathode material, which can account for nearly 40-45 percent of the total battery cost.
