The invention discloses a method for efficiently preparing an integrated
electrode of a
flow battery, which comprises the following steps of: S1, well mixing plastic, a conductive auxiliary agent and an auxiliary agent, and
processing a bipolar plate from the mixture; S2, pretreating
graphite felts; S3, attaching a layer of volatile
solvent to the surface of the bipolar plate; S4, tightly attaching the two pretreated
graphite felts to the two sides of the bipolar plate with the volatile
solvent attached to the surface to form a
graphite felt / bipolar plate / graphite felt sandwich structure; and S5, stacking multiple
layers of the graphite felt / bipolar plate / graphite felt sandwich structure, tightly laminating the multiple
layers through a tablet press, introducing a
direct current or an
alternating current, and embedding graphite felt
carbon fibers into the bipolar plate to form an integrated
electrode. The
flow battery integrated
electrode is prepared in a
current mode, the
internal resistance in the finished integrated electrode can be remarkably reduced, and the efficiency of the
flow battery is improved. The preparation method is simple, multiple integrated electrodes can be produced at a time, the production time is short, the efficiency is high, energy is saved, environment friendliness is achieved, and
mass production is facilitated.
