With the evolution of Li-ion batteries, they have been employed in many applications. However, high energy density and power density batteries are yet to be developed to meet the necessities at the application end. Sulfides are a good choice as anode material as they show a much higher specific capacity than conventional graphite anodes. But unfortunately, sulfide dissolution and polysulfide shuttling are big drawbacks for their operation. Herein, single phase ternary metal sulfide Cu 3 SnS 4 (CTS) nanoparticles are synthesized with high Cu : Sn ratio and examined for application as Li-ion battery anode. High specific capacities of 1082 mAh g À 1 at 0.2 A g À 1 and 440 mAh g À 1 at a high rate of 3 A g À 1 are realized with superior stability tested up to 950 cycles. Utilizing the CTS NPs can minimize the polysulfide dissolution. The high Cu : Sn ratio provides excess Cu atoms as the buffer matrix for volume expansion of Sn, leading to high stability and specific capacity. Compared to other reported Cu based mixed phase or composite ternary sulfide materials, the CTS NPs presented herein show a better performance. In a full cell device using LiCoO 2 (LCO) as cathode, a good performance is achieved as well with an energy density of 405 Wh/Kg at 0.1 A g À 1 . V-10 mA battery tester. The impedance and cyclic voltammetry were performed with VMP3 biologic system equipped with potentiostat and galvanostat channels.

The optimization of three‐dimensional (3D) MXene‐based electrodes with desired electrochemical performances is highly demanded. Here, a precursor‐guided strategy is reported for fabricating the 3D SnS/MXene architecture with tiny SnS nanocrystals (≈5 nm in size) covalently decorated on the wrinkled Ti3C2Tx nanosheets through Ti−S bonds (denoted as SnS/Ti3C2Tx‐O). The formation of Ti−S bonds between SnS and Ti3C2Tx was confirmed by extended X‐ray absorption fine structure (EXAFS). Rather than bulky SnS plates decorated on Ti3C2Tx (SnS/Ti3C2Tx‐H) by one‐step hydrothermal sulfidation followed by post annealing, this SnS/Ti3C2Tx‐O presents size‐dependent structural and dynamic properties. The as‐formed 3D hierarchical structure can provide short ion‐diffusion pathways and electron transport distances because of the more accessible surface sites. In addition, benefiting from the tiny SnS nanocrystals that can effectively improve Na+ diffusion and suppress structural variation upon charge/discharge processes, the as‐obtained SnS/Ti3C2Tx‐O can generate pseudocapacitance‐dominated storage behavior enabled by engineered surface reactions. As predicted, this electrode exhibits an enhanced Na storage capacity of 565 mAh g−1 at 0.1 A g−1 after 75 cycles, outperforming SnS/Ti3C2Tx‐H (336 mAh g−1), SnS (212 mAh g−1), and Ti3C2Tx (104 mAh g−1) electrodes.
