摘      要：The prototype material,Li_(1.23)Ru_(0.41)Ni_(0.36)O_(2),is proposed to gain the deep and comprehensive understanding of chemical and structural changes of the novel layered/rocksalt intergrown *** X-ray absorption spectra and resonant inelastic X-ray scattering reveal that both cationic and anionic redox evolves in the charge compensation process of the intergrown material,while synchrotronbased extended X-ray fine structure spectra and in situ X-ray diffraction measurements demonstrates that the intergrown material undergoes minimal local-and long-range structural variations at deep de/*** work highlights the great potential of the intergrown structure to inspire the design of advanced cathode materials for lithium-ion batteries.
