摘要 | Practical application of lithium metal anodes in high-energy rechargeable batteries is impeded by the issue of Li dendrite growth. Herein, an exceptional hydrophobic MAF-6 material is utilized to modify polypropylene (PP) separator to yield a superorganophilic MAF-6/PP composite separator. Owing to a combination of super-organophilicity with three-dimensional ordered porosity, the MAF-6/PP achieves a Li ion transference number of 0.78. Homogeneous and dense Li plating behaviors are present in cells with MAF-6/PP which can afford uniform Li ion flux. The MAF-6/PP enables Li vertical bar Cu cells to run steadily for over 350 cycles at 0.5 mA cm(-2) -1 mAh cm(-2) with an average coulombic efficiency (CE) of 98.8%, symmetric Li vertical bar Li cells to work stably for 2200 h without short-circuit at 0.5 mA cm(-2)-1 mAh cm(-2), and Li vertical bar LiFePO4 cells to retain a reversible capacity of 102.4 mAh g(-1) after 1500 cycles at 1C with a capacity retention of 73.2% and a CE of 99.9%. |
