SnS₂ has aroused great interests for application of sodium-ion batteries, because of its graphene-like structure and high theoretical capacity. Herein, we present an effective nanocasting strategy to fabricate the SnS₂/enteromorpha prolifera derived carbon (SnS₂/EPC) composite, whose microstructure anchors the SnS₂ nanosheets on enteromorpha prolifera (EP) derived carbon. It can effectively solve the problems of poor conductivity and volume expansion of SnS₂ electrode during charging and discharging process. The optimized SnS₂/EPC could deliver high reversible capacity of 443 mA h g⁻¹ at 0.1 A g⁻¹, and maintain reversible capacity of 340 mA h g⁻¹ at high rate of 2 A g⁻¹ after 450 cycles, indicating that SnS₂/EPC is a promising anode material for sodium storage.

SnS ₂由于其类似于石墨烯的结构和较高的理论容量，引起了钠离子电池应用的极大兴趣。在这里，我们提出了一种有效的纳米铸造策略，以制备SnS ₂ /肠小肠来源的碳（SnS ₂ / EPC）复合材料，其微结构将SnS ₂纳米片锚定在肠小肠（EP）来源的碳上。可以有效解决SnS ₂电极充放电过程中导电性差和体积膨胀的问题。优化的SnS ₂ / EPC在0.1 A g时可提供443 mA h g ^-1的高可逆容量^-1，并在450次循环后以2 A g ^-1的高速率维持340 mA h g ^-1的可逆容量，这表明SnS ₂ / EPC是一种有前途的钠存储阳极材料。
