Self‐Induced Concentration Gradient in Nickel‐Rich Cathodes by Sacrificial Polymeric Bead Clusters for High‐Energy Lithium‐Ion Batteries

A high-energy nickel-rich cathode with primary particle concentration gradient is developed via a simple, one-step process involving a sacrificial polymeric-bead cluster. The primary particles' gradients and internal buffer space in the secondary particles are successfully formed without any surface coating reagents. It is demonstrated that the cathode material has a high specific capacity and thermal stability.
