Abstract
A novel approach to develop a low-temperature lithium-ion battery (LIB) based on tin selenide (SnSe) and carbon (C) nanofibers as the active electrode material has been successfully achieved. The SnSe@C nanofiber anode exhibited excellent electrochemical properties, such as high capacity and good rate capability. The anode maintained a consistent charge capacity of ∼923 mAh g−1 at a current rate of 0.1 A g−1 over 100 cycles at room temperature. Furthermore, investigated for the first time at low temperatures, the SnSe@C nanofiber anode exhibited superior capacity (∼430 mAh g−1 at −20 °C) compared to conventional graphite electrode (∼25 mAh g−1 at −20 °C). The proposed SnSe@C nanofiber anode demonstrated a great potential to be applied for developing next-generation LIBs with improved low-temperature performance.
成功地实现了一种以硒化锡（SnSe）和碳（C）纳米纤维为活性电极材料开发低温锂离子电池（LIB）的新方法。这个SnSe@C纳米纤维阳极表现出优异的电化学性能，如高容量和良好的倍率性能。在室温下的100次循环中，阳极在0.1 a g−1的电流率下保持了约923 mAh g−1不变的充电容量。此外，首次在低温下进行了研究SnSe@C与传统石墨电极（−20°C时为～25 mAh g−1）相比，纳米纤维阳极表现出优异的容量（−20℃时为～430 mAh g–1）。拟议的SnSe@C纳米纤维阳极在开发具有改进低温性能的下一代LIBs方面显示出巨大的应用潜力。
