Tind iselenide (SnSe 2 ), as an anodem aterial,h as outstandingp otential for use in advanced lithium-ion batteries. However,l ike other tin-based anodes, SnSe 2 suffers from poor cycle life and low rate capabilityd ue to large volume expansion during the repeated Li + insertion/de-insertion process. This work reports an effectivea nd easy strategy to combine SnSe 2 and carbon nanotubes (CNTs) to form a SnSe 2 /CNTsh ybrid nanostructure. The synthesized SnSe 2 has ar egularh exagonal shape with at ypical 2D nanostructure and the carbon nanotubes combine well with the SnSe 2 nanosheets. The hybrid nanostructure can significantly reduce the serious damage to electrodes that occurs during electrochemical cycling processes. Remarkably,t he SnSe 2 / CNTse lectrodee xhibits ah igh reversible specific capacity of 457.6 mA hg À1 at 0.1 Ca nd 210.3 mA hg À1 after 100 cycles. At ac ycling rate of 0.5 C, the SnSe 2 /CNTse lectrode can still achieve ah igh value of 176.5 mA hg À1 ,w hereas av alue of 45.8 mA hg À1 is achieved for the pure SnSe 2 electrode. The enhanced electrochemical performance of the SnSe 2 /CNTs electrode demonstrates its great potential for use in lithiumion batteries.T hus, this work reports af acile approacht o the synthesis of SnSe 2 /CNTsa sap romising anode material for lithium-ionb atteries.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

Recycling of environmentally benign, highly abundant mineral resources and low-cost biomass for electrodes is urgently needed for the sustainable integration of energy storage devices. In the present study, we propose a rational design of a ternary composite by integrating Sn nanoparticles, a glass-phase SnSiO x+2 matrix, and a biomass deriving N-doped carbon framework via a one-pot, scalable annealing process. The synergistic effect of reversible Li+ storage properties originates from the complementary functionalities of each component: abundant functional groups grafted on the processed biomass anchor the metallic precursors for intimate coupling of the electroactive components, and the biomass-derived carbon framework serves as a conductive substrate for the ultrasmall Sn particles calcinated from the off-stoichiometric precursor ratio while glass-phase SnSiO x+2 accommodates the volume expansion of the Sn–Li alloy. The Sn/SnSiO x+2@C-650 composite anode displays an overall satisfactory cycle performance: the high areal capacity of 1.68 mA h cm–2 with average Columbic efficiency higher than 99% at 0.2 mA cm–2 and rate behavior up to 4 mA cm–2 are simultaneously realized in the half cell. We further establish a prototype full cell by pairing the Sn/SnSiO x+2@C-650 anode with the modified LiMn2O4 cathode: a remarkable cycling stability is maintained for 50 cycles with high gravimetric/volumetric energy densities. This biomass-templated strategy demonstrates a precise control over the structural and compositional features of a multinary composite for next-generation batteries.
