“…From the table, our measured volumetric capacity is comparatively higher than all but three of the reported literature values and is attributed to the higher bulk density of our hybrid structure. The table also shows that our volumetric capacity is lower than some reported values and this is due to the large thicknesses of the bulk framework. Generally, a hybrid framework with an initial thickness of 3.0–2.5 mm is used, which is then compressed to 0.20–0.15 mm in a coin cell.…”

“…The hybrid structure delivered an initial areal capacity of 6.54 mAh cm −2 and after 50 cycles it still retained at 4.0 mAh cm −2 , indicating excellent cyclic stability (Figure 5h) Further, a comparative study of the areal capacity of our 3D hybrid electrode with other electrodes is listed in Table S2 in the Supporting Information. The table also shows that our volumetric capacity is lower than some reported values [54][55][56] and this is due to the large thicknesses of the bulk framework. Using the total electrode volume in our calculations, we obtained a volumetric capacity of 158, 213, and 267 mAh cm −3 to correspond, respectively, to an areal mass loading of 7.41, 10.8, and 13.9 mg cm −2 for our trilayer CNT/ MoSe 2 /C∼3 framework ( Figure S8, Supporting Information).…”

attention because of its low cost and abundant supply of sodium. [1][2][3] However, because of its narrow interlayer spacing ≈0.34 nm, the larger size of Na + compared to Li + makes it difficult if not unsuitable for intercalation in graphite, which is commercially employed for LIB. [4][5][6] Further, the large radius of Na + in SIB electrodes produces sluggish electrochemical kinetics, provides higher diffusion barriers, and causes large volume expansion which leads to low rate capability and poor cyclic stability. [7,8] The ionization potential of Na + is also lower than Li + which results in a lower operating voltage and consequently, a lower energy density. [9] A lot of efforts in the development of advanced anode materials for SIBs have been proposed to address these issues.Recently, 2D transition metal dichalcogenides (TMDCs) have received considerable attention in electrochemical energy storage and conversion devices due to their layered structure, and the favorable electronic, chemical, and mechanical properties and stability. [10][11][12] TMDCs such as MoS 2 are often considered a promising anode candidate for LIBs. [13] However, when MoS 2 is employed in SIBs, it displays a lower capacity and a poor cyclic stability as a result of the low intrinsic conductivity and the small interlayer distance (≈0.62 nm). [14] In contrast, MoSe 2 possesses a slightly larger interlayer distance (≈0.64 nm) and better electrical conductivity due to small bandgap (≈1.1 eV). Moreover, it possesses higher theoretical capacity (≈422 mAh g −1 ) [10,15] than graphite (≈35 mAh g −1 ) [6] which makes it one of the most promising TMDC candidates for SIBs. However, the practical applications of MoSe 2 as an anode is limited by capacity fading due to the large volume expansion during long charging/discharging processes and the poor rate capability due to the low intrinsic electrical conductivity. [10] Modifying the nanostructure of the SIB electrodes can often solve some of these problems. For example, expanding the interlayer distance of MoSe 2 can lead to an improvement of the Na + storage and reducing the Na + diffusion barrier energy can enhance the reaction kinetics for the Na + intercalation/deintercalation. [16] Due to the high surface energy and weak van der Waal interactions between layers, Freestanding composite structures with embedded transition metal dichalcogenides (TMDCs) as the active material are highly attractive in the development of advanced electrodes for energy storage devices. Most 3D electrodes consist of a bilayer design involving a core-shell combination. To further enhance the gravimetric and areal capacities, a 3D trilayer design is proposed that has MoSe 2 as the TMDC sandwiched in-between an inner carbon nanotube (CNT) core and an outer carbon layer to form a CNT/ MoSe 2 /C framework. The CNT core creates interconnected pathways for the e − /Na + conduction, while the conductive inert carbon layer not only protects the corrosive environment between the electrolyte and MoSe 2 but also is fully tunable fo...

“…reported tetragonal iron tellurite (Fe 2 TeO 6 ) prepared by a facile calcination method and evaluated its use as an anode for LIBs and NIBs for the first time, as shown in Figure 20 a–g. [ 247 ] CV curves and ex situ XRD data revealed that iron tellurite transformed into Fe 2 O 3 and TeO 2 after the initial discharge and charge processes. It was demonstrated that both Li + and Na + ions reversibly reacted with Fe 2 O 3 and TeO 2 .…”

In this study, nickel tellurium oxide (Ni 3 TeO 6 ) was composited with carbon nanotubes (CNTs) through the high-energy ball-milling method and proposed as a high-energy conversion-type anode for sodium-ion batteries (SIBs) for the first time. Upon mechanical milling, the Ni 3 TeO 6 nanoparticles were uniformly encapsulated and wedged within the CNTs matrix, which produced a nano/micro hybrid structure. The interconnected CNT network in the composite provided conductive paths for rapid electron transport while effectively suppressing the local stress caused by large volume changes of Ni 3 TeO 6 during the sodiation-desodiation process. The Ni 3 TeO 6 @CNTs exhibited a high Na +ion storage capacity of 495 mA h g À1 , good cycling stability at 200 mA g À1 , and high-rate performance up to 2000 mA g À1 .
