Although the packing density of activated graphene has improved remarkably, compared to graphene it still cannot meet the requirements for practical application. One method to overcome the low packing density of the carbon-material-based electrode is to mechanically compress porous powders for supercapacitor electrodes. It is well known that porous carbon consists of macro and micropores, and micropores are considered to make a predominant contribution to the energy storage. Macropores are damaged but micropores are mainly remained during mechanical compression, thus, the compressed samples still remain good performance. More recently, Murali and coworkers [114] reported on the use of high pressure to compress the a MEGO for achieving high volumetric capacitance and energy density after compression. By using 25 tons compression force, a bulk density of 0.75 g/cm3 was obtained. The electrode exhibited a high volumetric capacitance of 110 F/cm3 using BMIMBF4/AN as the electrolyte at 3.5 V. Similarly, the volumetric energy density was increased from the uncompressed samples of 23 to 48 Wh/L for the compressed samples. Unfortunately, the rate capability was severely affected due to the ion transport channels (provided by maropores) being significantly reduced after mechanical compression. Very recently, Li and coworkers [115] reported a simple capillary compression of adaptive graphene gel films in the presence of nonvolatile liquid electrolyte to obtain porous yet densely packed graphene electrodes with high ion-accessible surface area and low ion transport resistance. The chemical converted graphene (CCG) hydrogel films obtained by filtration of CCG dispersion were exchanged with a miscible mixture of volatile and nonvolatile liquids (sulfuric acid, EMIMBF4) and were then subjected to removal of the volatile liquid by vacuum evaporation. The graphene sheets in the liquid mediated CCG (EM-CCG) films stacked in a nearly face- to-face fashion, and the packing density could be increased up to ~1.33 g/cm3. More important, the EM-CCG film electrode still remained a highly efficient ion transport channel; due to the fluid nature of liquid electrolytes, the continuous liquid network was likely to remain within the whole film during the capillary compression process. Furthermore, as the electrolyte became integrated within the film from the start of the assembly process, there was no subsequent wettability issue for these EM-CCG films, which remained a serious problem for the dried CCG film. As a result, the supercapacitors based on EM-CCG films could obtain volumetric energy densities approaching 60 Wh/L. Additionally, the EM-CCG films exhibited excellent cycle stability; over 95% of the initial capacitance remained after a 300-h constant voltage holding at 3.5 V in a neat EMIBF4 electrolyte. This means that the fabrication of CCG films and subsequent compression are essentially compatible with the traditional cost-effective paper-making process and can be readily scaled up. All these attractive features make this class of graphene materials promising for large-scale real-world applications.
