Fe(3)O(4)-PVDF Composite Network for Dendrite-Free Lithium Metal Batteries
Dendrite growth has been the main trouble preventing the practical application of Li metal anodes. Herein, we present how an Fe(3)O(4)-PVDF composite network prepared by using electrospinning has been designed to protect lithium metal anodes effectively. In the symmetrical cells test, the cell with...

description | Dendrite growth has been the main trouble preventing the practical application of Li metal anodes. Herein, we present how an Fe(3)O(4)-PVDF composite network prepared by using electrospinning has been designed to protect lithium metal anodes effectively. In the symmetrical cells test, the cell with the Fe(3)O(4)-PVDF composite network maintains good cycle performance after 600 h (500 cycles) at a current density of 1 mA cm(−2) and a plating/stripping capacity of 1 mAh cm(−2). The bulky Li dendrite is suppressed and a uniform Li deposition remains after long cycling. The characteristics of this engineered separator are further demonstrated in Li-S full cells with a good cycle performance (capacity of 419 mAh g(−1) after 300 cycles at 0.5 C). This work provides a new idea for the protection of lithium metal anodes. |
