Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) have been considered as attractive alternatives for next-generation battery systems, which have promising application potential due to their earth abundance of potassium and sodium, high capacity and suitable working potential, however, the design and application of bi-functional high-performance anode still remain a great challenge up to date. Bismuth sulfide is suitable as anode owing to its unique laminar structure with relatively large interlayer distance to accommodate larger radius ions, high theoretical capacity and high volumetric capacity etc. In this study, dandelion-like Bi_(2)S_(3)/rGO hierarchical microspheres as anode material for PIBs displayed reversible capacity, and 206.91 mAh·g^(−1) could be remained after 1,200 cycles at a current density of 100 mA·g^(−1). When applied as anode materials for SIBs, 300 mAh·g^(−1) could be retained after 300 cycles at 2 A·g^(−1) and its initial Coulombic efficiency is as high as 97.43%. Even at high current density of 10 A·g^(−1), 120.3 mAh·g^(−1) could be preserved after 3,400 cycles. The Na_(3)V_(2)(PO_(4))_(3)@rGO//Bi_(2)S_(3)/rGO sodium ion full cells were successfully assembled which displays stable performance after 60 cycles at 100 mA·g^(−1). The above results demonstrate that Bi2S3/rGO has application potential as high performance bi-functional anode for PIBs and SIBs.

Herein,a two-dimensional(2D)interspace-confined synthetic strategy is developed for producing MoS_(2)intercalated graphite(G-MoS_(2))hetero-layers composite through sulfuring the pre-synthesized stage-1 MoCI5-graphite intercalation compound(M0 CI5-GIC).The in situ grown MoS_(2)nanosheets(3-7 layers)are evenly encapsulated in graphite layers with intimate interface thus forming layer-by-layer MoS_(2)-intercalated graphite *** this structure,the unique merits of MoS_(2)and graphite components are integrated,such as high capacity contribution of MoS_(2)and the flexibility of graphite ***,the tight interfacial interaction between hetero-layers optimizes the potential of conductive graphite layers as matrix for MoS_(2).As a result,the G-MoS_(2)exhibits a high reversible Li+storage of 344 mAh·g^(-1)even at 10 A·g^(-1)and a capacity of 539.9 mAh·g^(-1)after 1,500 cycles at 5 A·g^(-1).As for potassium ion battery,G-MoS_(2)delivers a reversible capacity of 377.0 mAh·g^(-1)at 0.1 A·g^(-1)and 141.2 mAh·g^(-1)even at 2 A·g^(-1).Detailed experiments and density functional theory calculation demonstrate the existence of hetero-layers enhances the diffusion rates of Li^(+)and K^(+).This graphite interspace-confined synthetic methodology would provide new ideas for preparing function-integrated materials in energy storage and conversion,catalysis or other fields.

Large-scale low-cost synthesis methods for potassium ion battery(PIB) anodes with long cycle life and high capacity have remained challenging. Here, inspired by the structure of a biological cell, biomimetic carbon cells(BCCs) were synthesized and used as PIB anodes. The protruding carbon nanotubes across the BCC wall mimicked the ion-transporting channels present in the cell membrane, and enhanced the rate performance of PIBs. In addition, the robust carbon shell of the BCC could protect its overall structure, and the open space inside the BCC could accommodate the volume changes caused by K+insertion, which greatly improved the stability of PIBs. For the first time, a stable solid electrolyte interphase layer is formed on the surface of amorphous carbon. Collectively, the unique structural characteristics of the BCCs resulted in PIBs that showed a high reversible capacity(302 m Ah g-1at 100 m A g-1and 248 mAh g-1at500 m A g-1), excellent cycle stability(reversible capacity of 226 m Ah g-1after 2100 cycles and a continuous running time of more than 15 months at a current density of 100 m A g-1), and an excellent rate performance(160 mAh g-1at 1 A g-1). This study represents a new strategy for boosting battery performance, and could pave the way for the next generation of battery-powered applications.
