High Nickel Positive Electrode Materials Modified By Dry Particle Fusion

High-energy-density Ni-rich cathode materials suffer from the critical challenge of poor capacity retention due to micro-cracking and interfacial reactivity with electrolyte. Addition of foreign elements to some Ni-rich materials is known to stabilize their capacity over cycling. In this work, we established that the benefit of these elements coating on Ni-rich hydroxide precursors before synthesis is universal in presence of major dopants used …
