Template-free synthesis and lithium-ion storage performance of multiple ZnO nanoparticles encapsulated in hollow amorphous carbon shells
the rational design and facile synthesis of composite structures are still challenging issues for lithium-ion batteries (LIBs). Herein, a simple approach has been developed to prepare multiple core–shell structures of ZnO nanoparticles (NPs) encapsulated in hollow amorphous carbon (AC) shells. The as-synthesized ZnO@AC composites showed a uniform dispersion of ZnO NPs, compliant buffer AC shells,
由于电极材料的利用有限,复合结构的合理设计和简便合成仍然是锂离子电池(LIBs)面临的挑战。本文开发了一种简单的方法来制备封装在中空无定形碳 (AC) 壳中的 ZnO 纳米颗粒 (NPs) 的多核壳结构。合成后的 ZnO@AC 复合材料显示出均匀分散的 ZnO NP、柔顺的缓冲 AC 壳以及 ZnO NP 核和 AC 壳之间的纳米级空隙空间。由于其结构优点,ZnO@AC 复合材料被评估为锂离子电池的负极材料,并具有更高的库伦效率、高可逆容量、高倍率性能和更高的循环稳定性。
