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...

In article number 1901146, Naiqin Zhao, Shi‐Zhang Qiao and co‐workers confine 1T'‐ReS2 in 2D‐honeycombed carbon nanosheets for sodium‐ion battery anodes. The intended 2D‐honeycombed carbon protective layer and the strong interfacial interaction contribute to the ultra‐stable long‐term cycling and high rate performance.
