▎ 摘　　要

NOVELTY - Electrolysis device comprises a container (1), a conductive electrode (2), a growth substrate (3), a heating device (4) and a filtering device (5). The container comprises a bottom plate, a front baffle, a back baffle, a left side plate and a right side plate. The front baffle is provided with a first convex strip near the left side plate end. The back baffle is provided with a second convex strip symmetrical to the first convex strip. The first convex strip, the second convex strip and the left side plate form a pair of symmetrical grooves. USE - Electrolysis device for producing graphene. ADVANTAGE - The electrolysis device has simple structure, and improves conversion rate and production efficiency of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of electrolysis device for producing graphene.
