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.
