“…In the initial cathodic cycles of all anodes, the solid electrolyte interface (SEI) film is generated due to electrolyte decomposition. Hence, a large current is produced during the cathodic process which leads to irreversible capacity loss . The other sharp cathodic peaks can be attributed to multistep alloying reactions of Zn, Sn, and Na .…”

“…The anodic peaks (for all electrodes) appearing during the desodiation process in a voltage window of 0.3–0.7 V, as shown in Figure a, suggests the multistep dealloying process of Na–Zn and Na–Sn compounds. The oxidation peak at 0.78 and 0.98 V for ZnS:SnS, 0.83 V for ZnS:SnS@CNTs composite, and at 1.48 V for ZnS:SnS@rGO composite describes the desodiation of Na ions and reverse conversion of ZnS:SnS from Zn, Sn, and Na x S. ,,,, On the other hand, CV graphs for each electrode at different scan rates are shown in Figure S2a–c, where the anodic–cathodic peaks reversely swing with overpotential. It can be seen clearly that two distinct cathodic and individual anodic peaks arise in the recorded CV graphs for pristine and ZnS:SnS composite electrodes at various sweep rates.…”

The development of innovative materials with excellent electrochemical properties is immediately needed to dispel the problems of battery performance. In the present study, the hydrothermal method was applied to synthesize bimetallic sulfides (ZnS:SnS), which were then anchored on reduced graphene oxide (rGO) to produce ZnS:SnS@rGO composites or combined with carbon nanotubes (CNTs) to achieve ZnS:SnS@CNT composites. These composites were then investigated as electrodes for sodium-ion batteries, and their charge storage properties were analyzed. Nanostructures and the morphology of the as-prepared composites were examined by X-ray diffraction, scanning or transmission electron microscopy, and X-ray photoelectron spectroscopy. The specific charge capacity for the ZnS:SnS@CNT composite reaches 364 mA h g–1, while the ZnS:SnS@rGO composite shows 343 mA h g–1 at 0.1 C. Moreover, the inclusion of the conductive matrices also stabilizes the cycle life and rate capability even up to 5.0 C. Nyquist plots obtained as a result of impedance spectroscopy illustrate that the ZnS:SnS@CNT composite electrodes enable fast charge transfer due to lower charge transfer resistance of 44.4 Ω as compared to ZnS:SnS@rGO (i.e., 51.5 Ω) and bare ZnS:SnS (i.e., 68 Ω) electrodes. Electrochemical analysis proves that the presence of dual metal-sulfide ions combined with reduced graphene or CNTs as a conductive matrix results in considerably improved ion storage properties owing to the enhanced electronic conductivity, cushioned volume expansion, and provision of ionic transport highways through the electrode.

Trumpet‐Like ZnS@C Composite for High‐Performance Potassium Ion Battery Anode

ZnS has acquired increasing attention for high‐performance PIBs anode because of its remarkable theoretical capacity, and redox reversibility for conversion reaction. However, the larger volume variation and delayed reaction kinetics for the ZnS in the discharge/charge processes lead to pulverization and severe capacity degradation. Herein, the trumpet‐like ZnS@C composite was synthesized by template method by using sodium citrate as carbon source followed by vulcanization process. As potassium ion batteries (PIB) anode, ZnS@C composite exhibits good rate performance and long life (stable reversible capacity of 107.8 mAh/g over 2000 charge‐discharge cycles at 5 A/g and high reversible capacity of 310 mAh/g at 0.1 A/g). The outstanding electrochemical performance of the ZnS@C composite is ascribed to its unique structure, which can mitigate the volume expansion of ZnS in the charge discharge process, expand the contact area between the electrode and electrolyte, and improve the conductivity of electrode materials by the introduction of carbon layer. This method of synthesizing trumpet‐like ZnS@C composite provides an important strategy for obtaining potassium ion batteries anode with long cycle.
