“…Electrochemical evaluation. The bi-metal Ti x Ta (4−x) C 3 MXene nanoparticles' electrochemical performance as Li-ion host material was analyzed using potentiostatic cyclic voltammetry and galvanostatic chargedischarge cycling as per our earlier reports 6,60,61 . First, Ti x Ta (4−x) C3 MXene powder was mixed with conductive additive (super P carbon) and binder (PVDF) with a mass ratio of 80:10:10 in solvent (NMP).…”

A bi-metallic titanium–tantalum carbide MXene, TixTa(4−x)C3 is successfully prepared via etching of Al atoms from parent TixTa(4−x)AlC3 MAX phase for the first time. X-ray diffractometer and Raman spectroscopic analysis proved the crystalline phase evolution from the MAX phase to the lamellar MXene arrangements. Also, the X-ray photoelectron spectroscopy (XPS) study confirmed that the synthesized MXene is free from Al after hydro fluoric acid (HF) etching process as well as partial oxidation of Ti and Ta. Moreover, the FE-SEM and TEM characterizations demonstrate the exfoliation process tailored by the TixTa(4−x)C3 MXene after the Al atoms from its corresponding MAX TixTa(4−x)AlC3 phase, promoting its structural delamination with an expanded interlayer d-spacing, which can allow an effective reversible Li-ion storage. The lamellar TixTa(4−x)C3 MXene demonstrated a reversible specific discharge capacity of 459 mAhg−1 at an applied C-rate of 0.5 °C with a capacity retention of 97% over 200 cycles. An excellent electrochemical redox performance is attributed to the formation of a stable, promising bi-metallic MXene material, which stores Li-ions on the surface of its layers. Furthermore, the TixTa(4−x)C3 MXene anode demonstrate a high rate capability as a result of its good electron and Li-ion transport, suggesting that it is a promising candidate as Li-ion anode material.

“…Figure 6a shows the initial five CV curves of the uniform ZSS�NCNs at a scan rate of 0.1 mV s À 1 with the voltage range of 0.01-3.0 V. In the first discharge sweep, a sharp reduction peak observed at 1.43 V that disappear in the subsequent cycles corresponding to the electrolyte decomposition and the formation of solid electrolyte interface (SEI) film. [24,48,49] Subsequently, a cathodic peak centered at 1.32 V is due to the conversion reaction of SnSe 2 to Sn and Li 2 Se phase. [21,27] The peaks at 0.84 V is according to Li + insert into ZnSe particles with the conversion reaction and phase transformation to Zn and Li 2 Se.…”

Bimetallic selenide composites with multiple valence transitions and high theoretical capacities have attracted great attention as lithium-ion-battery anodes, but their rapid capacity fading and scarce research limit their development. Herein, novel hybrid ZnSe-SnSe 2 nanoparticles embedded in N-doped carbon nanocubes (ZSS�NCNs) are synthesized by a facile nucleation assembly, carbon coating, and in situ selenation route. The obtained uniform ZSS�NCN materials exhibit high surface area, N-doping carbon shell, extra inner void space, and excellent resilient mechanism nanostructure, which provide amounts of active sites, outstanding electrochemical kinetics, and buffer the volume expansion in the conversion and alloy/dealloy processes. For lithium-ion-battery half-cells, the uniform ZSS�NCN materials display a high initial coulombic efficiency of 81.9 %, an increased capacity of 846.6 mA h g À 1 at 0.2 A g À 1 after 100 cycles, and an excellent rate capability (414.1 mA h g À 1 at 5 A g À 1 ). When assembled with a LiMn 2 O 4 cathode, the ZSS�NCNs// LiMn 2 O 4 full cells also present excellent electrochemical properties. Ex situ XRD analyses at different potentials in the lithiation/ delithiation processes confirm a polymorphic phase transformation in the ZSS�NCNs. The synthesized ZSS�NCN enriched bimetallic selenide composites and the facile synthesis route provide a strategy for other bimetallic selenides, sulfide or phosphide composites with stable nanostructure to be utilized in energy storage.

“…With the Li/Na concentration increases on a popC 5 B sheet, no bond-breaking and irreversible reactions occur, and the volume changes of popC 5 B with various Li and Na insertion (Section S3 of the Supporting Information) achieve 18% and 39%, respectively. The volume changes are larger than those of graphite with lithiation (10%-12%), 53,54 but are smaller than those of black phosphorus (216% for lithiation and 391% for sodiation), 55 amorphous phosphorus (490% for sodiation), 56 Sb (200% for lithiation and 390% for sodiation), 57,58 Si (420% for lithiation), 57 Sn (260% 57 or 384% 59 for lithiation), Ge 2 Sb 2 Se 5 glass (26% for lithiation), 60 compounds of Ge and spherical carbon particles based anode (22% for lithiation), 61 SiC electrode (35% for lithiation), 62 and SiO/graphene/carbon anode (67% for lithiation). 63 In addition, although the popC 5 B with Li/Na atoms inserted is slightly distorted, it easily recovered to its original configuration when removed all Li/Na atoms, again suggesting good cycling stability and durability of popC 5 B as an anode material.…”

Defect engineering is a desired manner to promote the performance of electrodes. Herein, by employing the boron atom substitution and carbon-boron vacancy-vacancy pairs in graphene, a defect-induced two-dimensional new phase, popC 5 B, is formed. The evidences indicate that it has dynamic, thermal, and mechanical stabilities. When used as anodes in Li/Na-ion batteries, it possesses high theoretical specific capacities of 1891/1135 mAh/g. The high capacity is attributed to the synergy effect of various defect engineering and defectinduced phase transition that lead to the charge delocalization in popC 5 B and promote the electron transfer between metal ions and popC 5 B. This study demonstrates that the synergy effect of various kinds of defects could be an effective approach to acquire high performance electrodes in batteries.
