VGCF 3D conducting host coating on glass fiber filters for lithium metal anodes

We report a rational design of vapor grown carbon fiber (VGCF) 3D conducting host coating on a glass fiber filter for its use as a lithium metal anode to inhibit dendrite growth and enhance cycling stability. The high coulombic efficiency of 91.1% and stable cycling can bemaintained after 100 cycles (965 h) at the current density of 0.5 mA cm(-2) for the capacity of 2.5 mAh cm(-2) in the carbonate electrolyte.
