Particles caulked by built-in high stiffness frame with fast ion transport capability: A two-pronged approach to solve chemo-mechanical failure for high-performance Ni-rich cathode materials

A breathable inorganic–organic interface for fabricating a crack-free nickel-rich cathode with long-term stability

“…The surface modification of primary particles may help maintain the structural stability of the Ni-rich cathode. 30,31 The characteristic peaks from polyurea were recognized from the N 1s X-ray photoelectron spectroscopy (XPS) spectrum (Fig. S6, ESI†).…”
