Abstract CoP nanoflowers (CoP NFs) composed of hierarchical nanosheets are synthesized using a facile method that involves dealloying of CoAl alloys and a subsequent phosphorization process. The prepared CoP NFs exhibit high electrochemical performances as the anode material for both Li-ion and K-ion batteries. The obtained electrochemical performances can be attributed to the rationally designed structure that possesses high surface areas for electrolyte wetting, effective exposure of conversion and ion-storage sites, sufficient free spaces for volume-change accommodation, as well as rapid ion diffusion pathways during charge and discharge.

具有分层纳米片的 CoP 纳米花作为锂离子和钾离子电池的高性能阳极

摘要 由分层纳米片组成的 CoP 纳米花 (CoP NFs) 是使用一种简便的方法合成的，该方法涉及 CoAl 合金的脱合金和随后的磷化过程。制备的 CoP NFs 作为锂离子和钾离子电池的负极材料表现出很高的电化学性能。获得的电化学性能可归因于合理设计的结构，该结构具有用于电解质润湿的高表面积、转换和离子存储位点的有效暴露、足够的体积变化调节自由空间以及充电和充电过程中的快速离子扩散途径。释放。
