| 英文摘要 | The inferior reversibility of the formation/decomposition of the lithium peroxide (Li2O2) and its insolubility and insulation features result in poor energy efficiency and limited durability of state-of-the-art Li-O(2)batteries. Herein, we elaborately designed sisal-like CoSe(2)nanowires enriched with Se vacancies (V-Se-CoSe2) anchored on a scaffold of magnetron-sputtered N-doped carbon cloth (N-CC) to address the above challenges. The synergistic coupling of vacancy regulation with interfacial interaction can be used to tune the ability to adsorb active oxygen and intermediate species and enhance the interfacial electron transfer during oxygen redox reactions. Experimental results demonstrate that the V-Se-CoSe2@N-CC-based Li-O(2)battery demonstrates a substantially decreased overpotential (similar to 0.56 V) and extraordinary durability (over 955 h). This work indicates that the synergistic coupling of vacancy modulation and interface interaction is a promising strategy for effectively enhancing the comprehensive performance of Li-O(2)batteries, which provide prospective insights into the exploration of next-generation highly efficient metal-air batteries. |
