This work is focused on the relationship between electrochemical performance and morphology of LiNi1/3Co1/3Mn1/3O2 (NCM) in an aqueous rechargeable lithium battery, and provides a reference for the selection of novel battery materials. In this work, NCM microrods, microspheres, and nanoblocks were successfully synthesized by solvothermal, coprecipitation, and sol–gel methods, respectively. Of the three samples, NCM nanoblocks, which are formed by agglomeration of a large number of nanoparticles, show the best electrochemical performance. During cycling, the NCM nanoblock exhibits an initial discharge capacity of 137.4 mAh g−1 and an impressive capacity of 130.8 mAh g−1 after 20 cycles at a current density of 1C (=160 mA g−1). Even at a high current density of 50C, this NCM nanoblock provides a capacity of 50.1 mAh g−1, which shows the great potential of the nanoblock as a cathode in aqueous rechargeable lithium‐ion batteries.

Sun's works have shown that the rate performance of layered cathode materials can be enhanced by increasing the percentage of exposed {010} active planes . However, it is still a huge challenge to prepare layered materials with exposed {010} planes, as these high‐energy facets are easy to be vanished during synthesis…”

“…In contrast, as displayed in Figures S4 and S5 in the Supporting Information, the morphology of O3‐NaNM is a brick‐like structure and the thicknesses (around 205.8 nm) of {010} active facets are lower than that of O3‐NaLNMCM (around 384.7 nm). It is worth noting that the increased thickness of {010} active facets of O3‐NaLNMCM could provide more channels for the fast and efficient transportation of Na + , resulting in superior electrochemical performance . Moreover, the unique multiple‐layer oriented stacking nanosheet structure could greatly enhance the rate performance because of the short diffusion distances and increased electrode–electrolyte contact area.…”

Exposing {010} Active Facets by Multiple‐Layer Oriented Stacking Nanosheets for High‐Performance Capacitive Sodium‐Ion Oxide Cathode

et al. 2018

As one of the most promising cathodes for rechargeable sodium-ion batteries (SIBs), O3-type layered transition metal oxides commonly suffer from inevitably complicated phase transitions and sluggish kinetics. Here, a Na[Li Ni Mn Cu Mg ]O cathode material with the exposed {010} active facets by multiple-layer oriented stacking nanosheets is presented. Owing to reasonable geometrical structure design and chemical substitution, the electrode delivers outstanding rate performance (71.8 mAh g and 16.9 kW kg at 50C), remarkable cycling stability (91.9% capacity retention after 600 cycles at 5C), and excellent compatibility with hard carbon anode. Based on the combined analyses of cyclic voltammograms, ex situ X-ray absorption spectroscopy, and operando X-ray diffraction, the reaction mechanisms behind the superior electrochemical performance are clearly articulated. Surprisingly, Ni /Ni and Cu /Cu redox couples are simultaneously involved in the charge compensation with a highly reversible O3-P3 phase transition during charge/discharge process and the Na storage is governed by a capacitive mechanism via quantitative kinetics analysis. This optimal bifunctional regulation strategy may offer new insights into the rational design of high-performance cathode materials for SIBs.
