Abstract
A new SnSb/C nanocomposite based on Na alloying reactions is demonstrated as anode for Na-ion battery applications. The electrode can achieve an exceptionally high capacity (544 mA h g(-1), almost double that of intercalation carbon materials), good rate capacity and cyclability (80% capacity retention over 50 cycles) for Na-ion storage.
摘要
一种基于 Na 合金化反应的新型 SnSb/C 纳米复合材料被证明是一种用于钠离子电池的阳极。该电极具有极高的容量（544 mA h g(-1)，几乎是插层碳材料的两倍）、良好的倍率性能和循环稳定性（50 次循环后容量保持率为 80%），可用于钠离子存储。
