Uniform Lithium Deposition Induced by Polyacrylonitrile Submicron Fiber Array for Stable Lithium Metal Anode
Source abstract
Abstract
The lithium dendrite growth and low Coulombic efficiency (CE) during lithium plating/striping cycles are the main obstacles for practical applications of lithium metal anode. Herein, we demonstrate that polyacrylonitrile (PAN) submicron fiber array could guide the lithium ions to uniformly disperse and deposit onto current collector. The PAN submicron fiber array nearly does not increase the volume of electrode with ultralow mass. By this simple design, we achieved stable cycling of lithium metal anode with an average CE of ∼97.4% for 250 cycles at a current density of 1 mA cm –2 with total Li capacity of 1 mAh cm –2 .
