“…Therefore, we have reason to believe that the NCSe@TiVCT x heterostructure cathode has the potential for high-performance Mg ion storage. As shown in Figure 6a, we compared the various characteristics of the NCSe@TiVCT x heterostructure cathode with various RMB electrodes as reported in a previous study [8,9,27,36] and Table S1 [31,[36][37][38][39][40][41][42][43][44] in Supporting Information, we compared the NCSe@TiVCTx heterostructure with various reported cathode materials for RMBs for a variety of characteristics, particularly the cyclability, confirming that the NCSe@TiVCT x heterostructure cathode shows advantageous applied practical potential.…”

Magnesium‐ion batteries (MIB) have gradually attracted attention owing to their high theoretical capacity, high safety, and low cost. A bimetallic metal–organic framework self‐sacrificing template and a co‐assembly strategy are used to prepare a high‐performance, stable cycling NiSe2‐CoSe2@TiVCTx (NCSe@TiVC) heterostructure MIB cathode that can be used as a flexible integrated unit to power future self‐powered systems. Benefiting from the synergistic effect of TiVCTx MXene and NCSe, the NCSe@TiVC heterostructure electrode has a discharge‐specific capacity of 136 mAh g−1 at 0.05 A g−1 and high cycling stability of over 500 cycles; the assembled pouch‐cell device as flexible integrated unit exhibits good practicability. The magnesium ion storage mechanism is also validated using quantitative kinetic analysis, ex situ XRD, and XPS techniques. Density functional theory analysis indicates the most stable Mg‐atom adsorption sites in the heterostructure. This study broadens the possibilities for applying the TiVCTx MXene heterostructure to energy storage materials and future self‐powered flexible systems.

“…Mg, on the other hand, is known to be a challenging metal for battery applications, with slow diffusion, troublesome electrolyte-electrode kinetics and problems with proton intercalation and electrolyte decomposition, [5][6][7] and has only demonstrated the equivalent of Mg 0.004 Ti 3 C 2 T 2 (≈1 mAh g −1 , 25 cycles) when tested on micron sized Ti 3 C 2 T x . [3] Employing spacer groups to increase interlayer distance [8] and/or nano sizing the MXene [9,10] has shown increased capacities, but it can be difficult to determine whether these capacities are due to reversible Mg 2+ intercalation, or due to surface reactions, proton intercalation and/or cointercalation of electrolyte as with the case of MgCl + intercalation. [5,6,11] Much is unknown about MXene interlayer chemistry.…”

The 2D layered Ti3C2T2 MXene is known for its diverse chemistry and has been investigated as potential anode and cathode in Li, Na, and Mg batteries. Ti3C2T2 layers can stack in at least two different ways depending on the termination group chemistry. In addition, stacking and termination groups influence the diffusivity and energy of ions intercalated in the MXene. How stacking influences the diffusivity, and how intercalated ions influence the stacking stability are not fully understood. In this study, density functional theory simulations explore Li, Na, and Mg ions intercalated in Ti3C2T2 stacked in four different ways; two are experimentally verified, and previously discussed in literature, and two with limited experimental evidence. It is shown that the stacking can reduce diffusion by 8–20 orders of magnitude. It is also explained how the termination group chemistry and the intercalated Li/Na/Mg ions change the relative stability of the stackings. The stacking's influence on diffusion properties is explained by examining the coordination of the ions at different points along the migration path. It is suggested that Ti3C2T2 with significant fluorine termination can be well‐suited for especially Na anode use, and regardless of termination is unsuited as Mg cathode.

Lithium-ion batteries (LIBs) have gained significant market share in the field of consumer electronics, grid storage, and hybrid electric vehicles, because of its exceptional energy densities per unit volume (area or weight) compared to other electrochemical energy storage systems. However, they do approach its maximum practical capacities and efforts are underway to explore future battery systems with enhanced energy density than LIBs. There has been growing interest in incorporating multivalent ions such as Zn 2+ , Mg 2+ , and Al 3+ , since they offer greater volumetric energy densities than its monovalent counterparts like LIBs and sodium-ion batteries. It has long been acknowledged that replacing lithium with magnesium (Mg) ions in battery systems has many potential benefits such as low cost, excellent rate capability, high energy density, ease of handling, and eco-friendly. Yet, a few breakthroughs has been made in the advancement of rechargeable magnesium batteries (RMBs) since its first discovery in 2000. The success of RMBs has been hindered by the slow electrode kinetics and also the formation of passive layers on Mg metal surfaces seriously affecting its performance during Mg 2+ ion magnesiation/demagnesiation. This chapter provides comprehensive knowledge on the background of rechargeable Mg batteries, principles, and cell configuration, discussing key advancements made in the last two decades in terms of its electrode materials and electrolytes. Finally, a brief note on future research strategies is outlined. Highlights• Mg-ion batteries may replace Li-ion batteries to meet the demands of both consumer and industrial energy storage.
