WebSep 28, 2024 · We chose 20 mol kg –1 (M) NaFSI + 0.5 M Zn(TFSI) 2 WiBSE as the electrolyte where the high concentration of NaFSI reduces the amount of “free” water in the electrolyte, reducing onset of oxygen evolution reaction (OER) allowing the graphite to be oxidized, and provides FSI – anions. The motivation behind selection of this specific …
