An integrated electrochemical exfoliation and electrophoretic deposition (EPD) method is developed to achieve a high performance graphene supercapacitor. The electrochemical delamination of graphite sheet has obtained a low defected few‐layer graphene adorned with oxygen‐containing functional groups. Then, the EPD process produced a binder‐free electrode to alleviate the graphene restacking problem. The electrode prepared using a deposition voltage of 5V exhibits the highest specific capacitance of 145.95 F/g at 0.5 A/g from three‐electrode measurement. Moreover, this EPD‐prepared electrode also demonstrates superior electrochemical properties compared to electrodes fabricated using PVDF binder. In the real symmetrical cell, the EPD‐prepared electrode also shows excellent performance with a high rate capability of 82.31% (from 0.5 A/g to 10 A/g), high cycling stability of 95.00% (at 5 A/g) after 10,000 cycles, and rapid frequency response with short relaxation time (τ₀) of 9.73 ms. These results indicate that this integration method is beneficial to construct a high performance binder‐free supercapacitor electrode consisting of low‐defected graphene materials, low electrode resistance, and less agglomeration of graphene sheets by utilizing an environmentally friendly process.

Synthesis and performance of binder-free porous carbon electrodes in electrochemical capacitors

Abstract: Porous binder-free carbon electrodes were obtained by using cellulose filter paper through soft-salt template synthesis. The electrode thickness could be tuned, and a linear relationship with the specific capacitance in supercapacitors was established.
