“…Figure S7a,b (Supporting Information) present cyclic voltammetry (CV) curves at a scan rate of 0.2 mV s −1 for rGO@ReS 2 @N‐C and rGO@ReS 2 , respectively. They are similar to those of ReS 2 /C anode in a recent work . The ex situ XRD and HRTEM results confirmed that the ReS 2 disappears and Re/Na 2 S forms when ReS 2 /C discharge to 0.01 V.

a viable alternative to more widespread lithium-ion batteries (LIBs). This is because of low cost and ready availability of sodium. [4][5][6] However, the larger ionic radius of Na + (1.02 vs Li + 0.76 Å) leads to sluggish electrochemical kinetics, larger volume change, and unsatisfactory reversibility. Consequently, graphite, the commercial anode material of LIBs, cannot be directly used in SIBs because of suppressed electrochemical kinetics. [7,8] The development of an earth-abundant and low-cost anode material remains a significant research challenge to the fabrication of high-performance SIBs.Recently, transition metal dichalcogenides (TMDs) have attracted attention as potential anode materials for SIBs due to their unique physical and chemical properties. [9][10][11] MoS 2 , a typical TMD, has been widely investigated because of its layered structure with large interlayerspacing (6.15 Å) that is beneficial to insertion/extraction of Na + . [12][13][14] However, conductivity and Na + diffusion is restricted by its semi-conducting 2H-phase and relatively large van der Waals interaction between adjacent layers. This results in poor electrochemical performance. 1T-MoS 2 with metallic conductivity and interlayer-expanded MoS 2 with reduced van der Waals interaction, have therefore been extensively studied. [15][16][17][18] However the fabrication of a stable 1T-MoS 2 together with extremely weak interlayer coupling via a facile and low-cost method has not been reported.Inspiringly, ReS 2 (rhenium disulfide) is a new TMD known to exhibit both distorted 1T (1T′) phase and extremely weak interlayer van der Waals interaction. [19][20][21][22][23] This makes it highly suitable for application to LIBs and SIBs. [24][25][26] The theoretical capacity of ReS 2 is 428 mAh g −1 . This value is based on the conversion reaction between one atom of ReS 2 and four of Li + or Na + . Despite these intrinsic structural advantages, a drawback is that, ReS 2 nanosheets suffer from irreversible structural change on deep charge-discharge processing. Additionally, it is reported that the direction of the largest volume expansion is along the out-of-plane. [27,28] This significantly impedes electrochemical performance of anisotropic ReS 2 anode materials in SIBs. To the best of our knowledge, only limited research has been undertaken to address this, including preparation of ReS 2 (rhenium disulfide) is a new transition-metal dichalcogenide that exhibits 1T′ phase and extremely weak interlayer van der Waals interactions. This makes it promising as an anode material for sodium-ion batteries. However, achieving both a high-rate capability and a long-life has remained a major research challenge. Here, a new composite is reported, in which both are realized for the first time. 1T′-ReS 2 is confined through strong interfacial interaction in a 2D-honeycombed carbon nanosheets that comprise an rGO inter-layer and a N-doped carbon coating-layer (rGO@ReS 2 @N-C). The strong interfacial interaction between carbon and ReS 2 increases overallconduc...

“…A second strategy is to make hybrid samples with carbon-based material to achieve better electrochemical performance. [35,36] Graphene, as one of the most desirable carbon materials, has been used to buffer volume expansion during charge/discharge process and to enhance electron/ion conductivity and cycling stability of anode materials due to the large specific surface area, high electric conductivity, good mechanical properties, and excellent stability.

As a typical two‐dimensional (2D) layered material, (vanadium disulfide) VS2 has huge potentials for application in SIBs due to its large interlayer spacing and high conductivity compared to metal oxide or other 2D materials. Reduced graphene oxide (RGO) possesses exceptional electronic properties and large specific area favoring fast electron transport and rich redox sites. In this work, VS2 hollow flower spheres and RGO nanocomposites were developed for the first time, it was synthesized using a facile solvothermal method. Benefiting from the exceptional layered structure, when used as the anode material for SIBs at room temperature, the as‐prepared electrode material of VS2 hollow flower spheres @RGO (named as VS2 HFS/RGO) nanocomposites delivers a high reversible discharge specific capacity of around 430 mAh/g at current density of 100 mA/g, superior rate performance (2 A/g) and excellent cycling properties with the discharge capacity remained 350 mAh/g at 100 mA/g after 500 cycles. Results show that the kinetics of VS2 HFS/RGO nanocomposites were mainly a capacitive‐controlled storage process and the high capacity contribution were beneficial for good rate performance. This work could provide new approaches and potentials for exploring and searching high performances anode materials for the practical applications of SIBs.

(1 of 10)Improving surface morphology profiles, i.e., surface area and porosity, by nanostructure/surface engineering is effective in accommodating sodium's ionic and kinetic inadequacies. However, this strategy is limited to only activating the extrinsic pseudocapacitance in terms of improving surfacebased reactions. Herein, it is aimed to improve the sodiation performance by enhancement from both intrinsic and extrinsic pseudocapacitance to maximize sodiation potential of materials. A rarely reported but highly functional spinel MnCo 2 S 4 (MCS), is introduced and systematically analyzed using first-principles investigations, which exhibits energetically favorable charge-transfer states and strong Na-ions adsorption kinetics as well as diffusion channels (−3.65 and 0.40 eV respectively). The overall electrochemical redox profiles of the MCS nanostructure is revealed by in situ techniques, which disclose the commencing of partial and then a full conversion-type sodiation at low discharge potentials (0.52 V vs Na/Na + ) with fast Na-ions diffusivity. Assisted by surface engineering technology on the intrinsically pseudocapacitive MCS, the urchin-like morphology is instrumental in boosting and realizing sodium storage performance, especially the surface capacitive behavior (from 73.4% to 94.1%), prolonged cycling stability (>800 cycles), and high-rate capability (416 mAh g −1 at 10 A g −1 ), as well as exhibiting remarkable full cell capability (high rate at 2 A g −1 , >200 cycles at 200 mA g −1 ).
