Summary: Li+/Na+ exchange is an effective method for preparing high-performance Mn-based layered cathodes for Li-ion batteries. However, the detailed structural changes during the ion-exchange process are less studied. This study combines in situ synchrotron X-ray diffraction, density functional theory calculations, and electrochemical tests to investigate the structural changes during the ion-exchange process of an Mn-only layered cathode. The findings reveal the thermodynamic favorability of Li+/Na+ exchange and the presence of two tandem topotactic phase transitions.

Summary: In this study, two different types of porous structures in high-voltage lithium, manganese-rich layered cathodes are revealed, along with the significance of the interface between the cathode and electrolyte in solid-state batteries. Nanopores are found near the interface, while nanovoids are formed during in situ Li+ extraction. Despite the development of nanovoids, the layered structure is preserved.

Summary: To tackle the capacity fade and safety concerns associated with oxygen redox in Li-rich layered cathodes, an integrated strategy involving interlayer regulation and delocalization of Li2MnO3-like domain is proposed. The controllable interlayer through atomic layer deposition minimizes lattice mismatch and prevents structural degradation during cycling, while compositional control of the Li2MnO3-like domain inhibits oxygen release and enhances the thermal stability of the electrode. The optimized cathode material demonstrates a capacity retention of 94.0% after 200 cycles and a multilayer pouch cell exhibits an outstanding cycling performance with 80.4% capacity retention after 710 cycles, along with verified safety features.

Summary: This study reveals the correlation between surface facet and surface stability of layered cathodes. It demonstrates that certain surface facets are more resistant to mechanical cracking and chemical corrosion, which is beneficial for high-performance rechargeable batteries. This finding deepens the understanding of the mechanism behind surface stability and suggests that surface facet regulation can optimize battery materials.

Summary: Li-rich Ni-rich Li1.08Ni0.9Mn0.1O2 oxides with core-shell architecture were synthesized to improve their high-voltage cyclability. The thermally-driven atomic interdiffusion between the Mn-rich shell and the Ni-rich core formed a thickness-controllable Li-rich Mn-rich shell, ensuring exceptional structural reversibility for the layered Li-rich Ni-rich core in long-term cycling. The optimized core-shell Li1.08Ni0.9Mn0.1O2 achieved a capacity retention of 96% after 100 cycles at 0.1 C in the voltage range of 2.7-4.6 V, providing a new avenue for rational design of advanced cathode materials for LIBs and beyond.

Summary: LRMO, as a cathode material for the next generation commercial LIBs, has high capacity, low cost, and environmentally friendly characteristics. The anionic redox reaction is the origin of its high capacity, but it causes voltage hysteresis and capacity decay. The application of LRMO is limited by the degradation caused by irreversible O loss and phase transition, and modification of unstable oxygen is needed to improve its performance.

Summary: Despite significant progress in the development of Ti3C2Tx (MXene) electrodes for high-power batteries and supercapacitors, the role of anions in electrochemical energy storage and their ability to intercalate between MXene sheets remains unclear. It has been demonstrated that the insertion of anionic species into MXene within the potential range of interest for capacitive energy storage is unlikely, possibly due to the strong negative charge on Ti3C2Tx sheets terminated by functional groups.
