Summary: The present work investigates a new phenomenon observed during aluminum dissolution experiments for supercapacitors (SCs) stability investigation. Supercapacitor (SC) electrodes based on carbon-coated aluminum foils were cyclically electrochemically treated in harsh conditions using bis-trifluoromethylsulfonyl imide (TFSI)-based electrolyte and Acetonitrile (ACN) as solvent. Dissolution of aluminum and subsequent plating on the carbonaceous surface were observed. The same process could also be reproduced on standard SC activated carbon electrodes. This mechanism suggests a potential strategy for achieving competitive Al film deposition by electroplating instead of the common copper counterpart.
