Rechargeable batteries are most important energy storage devices in modern society with the rapid development and increasing demand for handy electronic devices and electric vehicles. The higher surface-to-volume ratio two-dimensional (2D) materials, especially transition metal dichalcogenides (TMDCs) and transition metal carbide/nitrite generally referred as MXene, have attracted intensive research activities due to their fascinating physical/chemical properties with extensive applications. One of the growing applications is to use these 2D materials as potential electrodes for rechargeable batteries and electrochemical capacitors. This review is an attempt to summarize the research and development of TMDCs, MXenes and their hybrid structures in energy storage systems. The strong demand for futuristic energy-storage materials and devices are exceptionally increasing owing to the request of more powerful energy storage systems with excellent power density and better cycle lifetime.1,2 For this reason, serious efforts have been undertaken to improve the electrode performance to achieve significantly improved the capacity, high rate capability and longer cycle life.3 Recently, 2D materials (TMDCs and MXene) have attracted intensive research activities due to their potential for broad applications.4-6 TMDCs represent a family of layered materials MX 2 (where M = one layer of transition metal and X = chalcogens) as shown in Figure 1a. [7][8][9] Figure 1b represents, three main structural polytypes, 1T, 2H and 3R of TMDCs. All three polytypes have layered structures with six fold trigonal prismatic coordination of transition metal atoms by the chalcogens within the TMDC layers. The term 1T, 2H and 3R represents the presence of one (1), two (2) and three (3) layers in the tetragonal (T), hexagonal (H) and rhombohedral (R) unit cell respectively. Interestingly, TMDCs own varied electronic structure, thus possess insulating (HfS 2 ), semi-conducting (MoS 2 , WS 2 ), semi-metallic (VS 2 , TiS 2 ), and superconducting (TaSe 2 , NbSe 2 ) behaviors which make them more attractive. Figure 1c, represents the exfoliation process of bulk TMDCs by lithium, sodium or potassium ion intercalation into the interlayer space and form ion-intercalated compounds, which can be further sonicated in water or organic solvents to produce single/few layer TMDC dispersions. More excitingly, the layers of TMDCs are connected with weak van der Waals interactions which enable them to serve for wide range of energy applications including energy generator, 10 energy storage 11-14 and catalysis. [15][16][17][18][19] On the other hand, MXenes 20 are produced from the MAX phase which is defined with the composition M n+1 AX n , where M = transition metal (i.e. Ti, V, Cr, Nb), A = group A element (i.e. Al, In, Sn, Si), X = carbon/nitrogen, and n = 1-3. Careful inscription of the group-A element from the MAX phase resulting in the production of MXene 20-24 as shown in Figures 1d-1e. One of the most studied applications of these 2D materials is to use t...

Lithium-ion batteries are widely used as reliable electrochemical energy storage devices due to their high energy density and excellent cycling performance. The search for anode materials with excellent electrochemical performances remains critical to the further development of lithium-ion batteries. Tungsten-based materials are receiving considerable attention as promising anode materials for lithium-ion batteries owing to their high intrinsic density and rich framework diversity. This review describes the advances of exploratory research on tungsten-based materials (tungsten oxide, tungsten sulfide, tungsten diselenide, and their composites) in lithium-ion batteries, including synthesis methods, microstructures, and electrochemical performance. Some personal prospects for the further development of this field are also proposed.

Intergranular cracking of Ni‐rich layered LiNi1‐x‐yCoxMnyO2 (1‐x‐y ≥ 0.8) cathode particles deteriorate the chemo–electro–mechanical stability of high‐energy lithium‐ion batteries (LIBs), thus presenting a challenge to typical modification methods to establish robust structures with highly efficient lithium‐ion storage. Herein, the ZrTiO4 (ZTO) as an epitaxial layer to enhance mechanical stability of ultrahigh‐Ni LiNi0.9Co0.05Mn0.05O2 (NCM90) is reported for the first time. Intensive exploration from structure characterizations (X‐ray absorption spectroscopy and in situ X‐ray diffraction techniques), multi‐physics field analysis, and first‐principles calculations disclose that the conformal ZTO layers and Zr doping effectively suppresses the internal strain and the release of lattice oxygen, which prodigiously restrains the local stress accumulation during whole (de)lithiation processes, thereby maintaining good mechanical stability of the materials. Meanwhile, the protective ZTO layer also prevents electrolyte erosion, thus keeping an intact surface structure of NCM90. Notably, ZTO‐modified NCM90 achieves significantly improved cyclability under high‐voltage (4.5 V) operation, expressing a 17% increase in capacity retention (71% vs 88%) after 100 cycles. Overall, this work reveals the role of internal strain in the original degradation behavior and effectiveness of surface engineering strategy to solve the challenge, emphasizing that the conformal surface protection mitigates the internal stress of Ni‐rich NCM by anchoring the lattice oxygen.
