Figure 1: Schematic of the fabrication of the Li-coated PI matrix.
From: Lithium-coated polymeric matrix as a minimum volume-change and dendrite-free lithium metal anode

Electrospun PI was coated with a layer of ZnO via ALD to form core-shell PI-ZnO. The existence of ZnO coating renders the matrix ‘lithiophilic’ such that molten Li can steadily infuse into the matrix. The final structure of the electrode is Li coated onto a porous, non-conducting polymeric matrix. Scale bar, 1 cm.
