SnS /graphene composites have attracted extensive attention in energy storage owing to their excellent electrochemical performance. However, most of the previous methods to synthesize SnS /graphene composites require long times, high temperatures, or high pressures, which are obstacles for practical low-cost production. A simple one-pot strategy to prepare SnS /graphene composites has been developed, which is not time-consuming (1 h) and requires moderate temperature (75 °C) in atmosphere. Through this method, ultrafine SnS nanoparticles anchored on graphene nanosheets are prepared and exhibit excellent electrochemical performance for both lithium and sodium storage. Specifically, as anodes for lithium-ion batteries, the SnS /graphene electrode delivers a high capacity of 1480 mAh g after 50 cycles at 0.2 A g . Even at 10 A g , the SnS /graphene electrode can achieve a capacity of 666 mAh g . A constructed full lithium-ion cell exhibits a capacity of 957 mAh g after 50 cycles at 1 A g . This simple one-pot strategy may pave the way for large-scale production and practical application of SnS /graphene composites in energy storage.

It is crucial to design advanced electrodes with large Li/Na-ion storage capacities for the development of next-generation battery systems. Herein, hierarchical MoS /C composite microspheres were constructed by facile template-free self-assembly sulfurization plus post-carbonization. Cross-linked MoS nanosheets and outer carbon layer are organically combined together to form composite microspheres with diameters of 400-500 nm. Due to enhanced electrical conductivity and good structural stability, the MoS /C composite microspheres exhibit substantially improved Li/Na-ion storage performance. Compared to unmodified MoS , MoS /C composite microspheres deliver higher Li/Na-ion storage capacity (Li : 1017 mA h g at 100 mA g and Na : 531 mA h g at 100 mA g ), as well as better rate capability (Li : 434 mA h g at 1 Ag and Na : 102 mA h g at 1 Ag ) and capacity retention (Li : 902 mA h g after 200 cycles and Na : 342 mA h g over 100 cycles). The superior Li/Na-ion storage performance is mainly attributed to the unique porous microsphere architecture with increased electrode/electrolyte interfaces and more diffusion paths for Li/Na ion insertion. Additionally, the carbon coating can not only improve the electronic conductivity, but also suppress the shuttle effect of polysulfides.

cathode of LIBs. Recently, Li-rich cathode materials (LMNCO), x Li 2 MnO 3 ·(1 − x) LiTMO 2 (0 < x < 1, TM = Mn, Ni, Co, etc.), have received extensive attentions due to their promising reversible capacity (>250 mAh g −1 ), environmental benignity, and low cost. [3] Nevertheless, the sluggish diffusion of electrons and lithium ions within LMNCO results in electrode polarization and inferior rate capability. [4] It has been verified that the electrochemical performance of LMNCO is closely connected with the morphology and structure, thereby rational design and control of the formation process for LMNCO is considered to be an effective route to enhance the capacity retention and rate capability. [5][6][7][8][9] On the basis of this, extensive efforts have been devoted to develop nanometersized materials and great progresses have been achieved over the past several years, such as construction of nanoplates, [5] nanowires, [10] nanoparticles, [11] and nanorods, [12] which possess a short Li + diffusion pathway thanks to their diminished dimensions. However, severely undesired side reactions between nanoscale electrode/electrolyte are detrimental to structural stability. [13] In order to address these challenges of nanometer-sized materials, hierarchical micro/nano-materials have been developed recently. [14][15][16] Hierarchical LMNCO possessed stable framework of micro-materials can achieve the prolonged cycle life through reducing interfacial reaction with electrolytes. [16] However, individual hierarchical structure strategy may be not enough, as the rate capability and cycling stability of the hierarchical LMNCO still need to be further improved. [17,18] Recent reports have evidenced two-dimensional (2D) nanostructure owns the advantages of open electrons and ions transport path, high active surface area, and excellent structure stability by accommodating the drastic volume evolution, which makes it applicable for ultrahigh-rate and cycling-stable lithium storage. [19][20][21] In addition, 2D nanosheets often have large exposed surface areas and specific facets. [22,23] It has been reported that in LMNCO cathodes, if the surfaces are parallel to {010} facets (e.g., (010), (100), and (110) planes), perpendicular to (001) plane, the Li + diffusion kinetics will be substantially strengthened. [15,16,24,25] Consequently, the synergistic effect of the 2D nanosheets, hierarchical structure, and Li-rich oxide is a promising candidate for the cathodes of next-generation lithium-ion batteries. However, its utilization is restricted by cycling instability and inferior rate capability. To tackle these issues, three-dimensional (3D), hierarchical, cube-maze-like Li-rich cathodes assembled from two-dimensional (2D), thin nanosheets with exposed {010} active planes, are developed by a facile hydrothermal approach. Benefiting from their unique architecture, 3D cube-maze-like cathodes demonstrate a superior reversible capacity (285.3 mAh g −1 at 0.1 C, 133.4 mAh g −1 at 20.0 C) and a great cycle stability (capacity retention of ...
