NOVELTY - This utility new type of question is a one graphene a c (1), include the electrolytic groove (10), a clamp (18), at least one first electrode (11), at least one second electrode (12), graphite material (13) and a porous fill material (14). Electrolytic groove can fill electrolyte (S), at least one second electrode and the first electrode relative set. And the clamp is clamped first electrode and second electrode. The graphene material a set with the second electrode. Porous fill material set on the first electrode and a second electrode. This utility new type through a porous fill material which makes the electrolyte be uniform with the electrode of a graphene material reaction. Therefore, a can provide a low at normal temperature, low cost, improve the efficiency and increase the whole a high quality of a graphene device.
