摘要
Developing an anode material that has better performance efficiency than commercial graphite while keeping the features of economic scalability and environmental safety is highly desirable yet challenging. MOFs are a promising addition to the ongoing efforts, however, the relatively poor performance, chemical instability, and large‐scale economic production of efficiency‐proven pristine MOFs restrict their utility in real‐life energy storage applications. Furthermore, hierarchical porosity for lucid mass diffusion, high‐density lithiophilic sites are some of the structural parameters for improving the electrode performance. Herein, we have demonstrated the potential of economically scalable salicylaldehydate 3D‐conjugated‐MOF (Fe‐Tp) as a high‐performance anode in Li‐ion batteries: the anode‐specific capacity achieved up to 1447 mA h g‐1 at 0.1 A g‐1 and 89% of cyclic stability after 500 cycles at 1.0 A g‐1.for pristine MOF. More importantly, incorporating 10% Fe‐Tp doping in commercial graphite (MOFite) significantly enhanced lithium storage, doubling capacitance after 400 cycles. It signifies the potential practical utility of Fe‐Tp as a performance booster for commercial anode material.
