▎ 摘　　要

NOVELTY - Electrolytic solution comprises nickel ion, and aqueous solution of borate ion and additive. The additive is used for promoting stripping of electroplating layer. USE - The electrolytic solution is used for electroplating substrate including carbon carbon felt, carbon cloth, graphite felt, graphene film, graphene net, carbon nanotube film, carbon nanotube paper, conductive active carbon film, mesoporous carbon film, conductive graphite plate, conductive graphite net, or iron, cobalt, copper, zinc, gold, platinum, silver or titanium metal substrate; or used for preparing aqueous battery (all claimed). ADVANTAGE - The electrolytic solution promotes stripping of plating layer. DESCRIPTION OF DRAWING(S) - The drawing shows an electrochemical graph of electroplating stripping of electrolytic solution on carbon substrate.
