“…Hence, the ion transport capability along with suitable active sites for kaolin coating could effectively shorten the migration path of zinc ions besides the function of artificial SEI layer. [ 23 ] However, the excess of kaolin coating will in turn raise the charge‐transfer resistance with reduction from Zn 2+ to Zn 0 due to the low ionic conductivity and interface resistance between kaolin particles. [ 24 ] Therefore, the KL coating obviously demonstrates the lower charge transfer resistance and the one with a moderate thickness of 21 µm is selected to demonstrate its superiority of building KL coating layer.…”

Zinc metal is considered as one of the best anode choices for rechargeable aqueous Zn-based batteries due to its high specific capacity, abundance, and safety. However, dendrite and corrosion issues remain a challenge for this system. Herein, sieve-element function (selective channel of Zn 2+ ) and uniform-pore distribution (≈3.0 nm) of a kaolin-coated Zn anode (KL-Zn) is proposed to alleviate these problems. Based on the artificial Zn metal/electrolyte interface, the KL-Zn anode not only ensures dendritefree deposition and long-time stability (800 h at 1.1 mA h cm −2 ), but also retards side reactions. As a consequence, KL-Zn/MnO 2 batteries can deliver high specific capacity and good capacity retention as well as a reasonably well-preserved morphology (KL-Zn) after 600 cycles at 0.5 A g −1 . This work provides a deep step toward high-performance rechargeable Zn-based battery system.

“…Figure 8b displays the Nyquist plots of the Ti 3 C 2 and Ti 3 C 2 /NiCo-MOF electrodes. The inset in Figure 8b is an equivalent circuit model that includes bulk electrolyte resistance (R s ), the charge transfer resistance R ct , and the Warburg resistance (W s ) related to Li + ions diffusion in the bulk electrode [43]. As shown in the Nyquist plots, the depressed semicircle in the medium-to-high frequency region represents R ct , and an inclined line in the low frequency range corresponds to W s .…”

To improve Li storage capacity and the structural stability of Ti3C2 MXene-based electrode materials for lithium-ion batteries (LIBs), a facile strategy is developed to construct three-dimensional (3D) hierarchical porous Ti3C2/bimetal-organic framework (NiCo-MOF) nanoarchitectures as anodes for high-performance LIBs. 2D Ti3C2 nanosheets are coupled with NiCo-MOF nanoflakes induced by hydrogen bonds to form 3D Ti3C2/NiCo-MOF composite films through vacuum-assisted filtration technology. The morphology and electrochemical properties of Ti3C2/NiCo-MOF are influenced by the mass ratio of MOF to Ti3C2. Owing to the interconnected porous structures with a high specific surface area, rapid charge transfer process, and Li+ diffusion rate, the Ti3C2/NiCo-MOF-0.4 electrode delivers a high reversible capacity of 402 mAh g−1 at 0.1 A g−1 after 300 cycles; excellent rate performance (256 mAh g−1 at 1 A g−1); and long-term stability with a capacity retention of 85.7% even after 400 cycles at a high current density, much higher than pristine Ti3C2 MXene. The results highlight that Ti3C2/NiCo-MOF have great potential in the development of high-performance energy storage devices.

Vortex Fluidic Mediated Synthesis of TiO₂ Nanoparticle/MXene Composites

et al. 2020

View full text Add to dashboard Cite

Oxidation of MXene in a vortex fluidic device (VFD) operating under continuous flow results in exfoliation and fragmentation into nanoparticles of surface oxidised 2D material with further oxidation of the nanoparticles into anatase (TiO2). These MXene and anatase nanoparticles co‐assemble into stable micron sized spheres which are topologically smooth, decorating the surface of exfoliated MXene. The formation of this composite material in the dynamic thin film in the VFD was optimised by systematically exploring the operating parameters of the microfluidic platform, determined at 45° tilt angle for the 20 mm diameter glass tube spinning at 5k rpm, with a flow rate of a colloidal dispersion of MXene in aqueous H2O2 (30%) at 0.75 mL/min at a concentration of MXene of 0.5 mg/mL.
