In　most　cases,　transfer　of　chemical-vapor-deposited　2D　materials　from　metallic　foil　catalysts　onto　a　target　substrate　is　the　most　necessary　step　for　their　promising　fundamental　studies　and　applications.　Recently,　a　highly　efficient　and　nondestructive　electrochemical　delamination　method　has　been　proposed　as　an　alternative　to　the　conventional　etching　transfer　method,　which　alleviates　the　problem　of　cost　and　environment　pollution　because　it　eliminates　the　need　to　etch　away　the　metals.　Here,　the　mechanism　of　the　electrochemical　bubbling　delamination　process　is　elucidated　by　studying　the　effect　of　the　various　electrolytes　on　the　delamination　rate.　A　capacitor-based　circuit　model　is　proposed　and　confirmed　by　the　electrochemical　impedance　spectroscopy　results.　A　factor　of　27　decrease　in　the　time　required　for　complete　graphene　delamination　from　the　platinum　cathodes　is　found　when　increasing　the　NaOH　ratio　in　the　electrolyte　solution.　The　opposite　trend　is　observed　for　delamination　at　the　anode.　The　surface　screening　effect　induced　by　nonreactive　ions　in　the　vicinity　of　the　electrodes　plays　a　key　role　in　the　delamination　efficiency.　The　analysis　is　generic　and　can　be　used　as　a　guideline　to　describe　and　design　the　electrochemical　delamination　of　other　2D　materials　from　their　metal　catalysts　as　well.
