The development of biosynthetic materials is a front research area that offers significant possibility to design electrode materials with improved performance for energy storage. Here, we demonstrate a dual-carbon layer strategy for constructing SnS2 composite electrode material, where nitrogen doped carbon fibers derived from fungus and PDA carbon layer function as confined template and reinforced layer, respectively (C@SnS2@NCFs). When used as the anode material for the sodium ion battery, the C@SnS2@NCFs electrode exhibits good cycle stability of 382 mAh g(-1) after 100 cycles at 0.1 A g(-1) and rate performance of 158 mAh g(-1) at 10 A g(-1). Such good performances are benefited from the dual-carbon structure, which greatly restricts the expansion of the SnS2 crystal and the dissolution of polysulfide during the cycle and ensures the stability of the electrode structure.
