(a) Schematic representation of the Li metal/cellulose acetate (CA) separator/ Li metal symmetry cell architecture. (b) chronopotentiometry results of symmetry cell with the polymeric Celgard separator (blue line) and the 1:0.23 CA/Ni(NO3)2 polymer separator at a water pressure of 2 bar (red line). (c) The Nyquist plots of symmetry cells with Celgard (blue dots) and CA (red dots) separators as a function of cycle number (d) Schematic representation of the Li metal/CA separator/LTO half-cell architecture. (e) Galvanostatic discharge-charge profiles of half-cell with the 1:0.23 CA/Ni(NO3)2 polymer separator at a water pressure of 2 bar. (f) Rate performance of Li metal/CA separator/LTO half-cell.
