With a decade of effort, significant progress has been achieved in the synthesis, processing, and applications of MXenes. Metal ions play many crucial roles, such as in MXene delamination, structure regulation, surface modification, MXene composite construction, and even some unique applications. The different roles of metal ions are attributed to their many interactions with MXenes and the unique nature of MXenes, including their layered structure, surface chemistry, and the existence of multi‐valent transition metals. Interactions with metal ions are crucial for the energy storage of MXene electrodes, especially in metal ion batteries and supercapacitors with neutral electrolytes. This review aims to provide a good understanding of the interactions between metal ions and MXenes, including the classification and fundamental chemistry of their interactions, in order to achieve their more effective utilization and rational design. It also provides new perspectives on MXene evolution and exfoliation, which may suggest optimized synthesis strategies. In this respect, the different effects of metal ions on MXene synthesis and processing are clarified, and the corresponding mechanisms are elaborated. Research progress on the roles metal ions have in MXene applications is also introduced.

“…The peak located at 0–0.5 V can be ascribed to the insertion of the Li + insertion in the carbon lattices [27] . In the initial anodic scan, the peak at 1.96 V can be corresponded with the delithiation of Li x Nb 2 O 5 [32,33] . Furthermore, in the subsequent cycles, the CV curves of Nb 2 O 5 /C submicrostructures are almost overlapped, implying a reversibility for Li + storage in the Nb 2 O 5 /C composites.…”

Nb2O5 possesses superior fast Li+ storage capability for LIB anodes, benefiting from its fast pseudocapacitive behavior and low volumetric change within the cycling processes. However, the poor electric conductivity for Nb2O5 restricts its reaction kinetics and rate property. Herein, Nb2O5/carbon (C) submicrostructures are fabricated by solvothermal method followed by calcination process. The Nb2O5/C submicrostructures exhibit outstanding rate behavior and cyclic performance (332 (194) mAh g−1 after 1000 cycles at 1 (5) A g−1). The superior electrochemical property is attributed to the distinctive structure for Nb2O5/C submicrostructures, in which Nb2O5 nanoparticles uniformly distributed within Nb2O5/C composite can protect Nb2O5 nanoparticles from agglomeration, and the porous carbon matrix can enhance electron/ion conductivity. This work furnishes a novel strategy for fabricating Nb2O5/C submicrostructures with superior Li+ storage performance, which can be potentially used to design other metal oxide/C submicrostructures for second battery anode.

Prussian blue analogues (PBAs) are believed to be intriguing anode materials for Li + storage because of their tunable composition, designable topologies, and tailorable porous structures, yet they suffer from severe capacity decay and inferior cycling stability due to the volume variation upon lithiation and high electrical resistance. Herein, we develop a universal strategy for synthesizing small PBA nanoparticles hosted on two-dimensional (2D) MXene or rGO (PBA/MX or PBA/rGO) via an in situ transformation from ultrathin layered double hydroxides (LDH) nanosheets. 2D conductive nanosheets allow for fast electron transport and guarantee the full utilization of PBA even at high rates; at the meantime, PBA nanoparticles effectively prevent 2D materials from restacking and facilitate rapid ion diffusion. The optimized Ni 0.8 Mn 0.2 -PBA/MX as an anode for lithium-ion batteries (LIBs) delivers a capacity of 442 mAh g −1 at 0.1 A g −1 and an excellent cycling robustness in comparison with bare PBA bulk crystals. We believe that this study offers an alternative choice for rationally designing PBA-based electrode materials for energy storage.
