主　　题：Cation mixing Layered oxide cathodes Lithium-ion batteries Electrochemical performance 

摘      要：High-performance lithium-ion batteries(LIB)are important in powering emerging *** are regarded as the bottleneck of increasing battery energy density,among which layered oxides are the most promising candidates for ***,a limitation with layered oxides cathodes is the transition metal and Li site mixing,which significantly impacts battery capacity and cycling *** recent research on Li/Ni mixing,there is a lack of comprehensive understanding of the origin of cation mixing between the transition metal and Li;therefore,practical means to address ***,a critical review of cation mixing in layered cathodes has been provided,emphasising the understanding of cation mixing mechanisms and their impact on cathode material *** list and compare advanced characterisation techniques to detect cation mixing in the material structure;examine methods to regulate the degree of cation mixing in layered oxides to boost battery capacity and cycling performance,and critically assess how these can be applied *** appraisal of future research directions,including superexchange interaction to stabilise structures and boost capacity retention has also been *** will be of immediate benefit in the design of layered cathodes for high-performance rechargeable LIB and,therefore,of interest to researchers and manufacturers.
