“…A separator allows transfer of ionic charge due to its ion permeability. [4][5][6][7][8] However, based on our knowledge, there is no review paper available on graphene-based ternary composite as electrodes for supercapacitor that has been reported yet. 2 Supercapacitors can store far more energy than conventional capacitors and able to deliver high specific power compared with batteries.…”

Summary The research on electrode materials for supercapacitor application continues to evolve as the request of high‐energy storage system has increased globally due to the demand for energy consumption. Over the past decades, various types of carbon‐based materials have been employed as electrode materials for high‐performance supercapacitor application. Among them, graphene is 1 of the most widely used carbon‐based materials due to its excellent properties including high surface area and excellent conductivity. To exploit more of its interesting properties, graphene is tailored to produce graphene oxide and reduced graphene oxide to improve the dispersibility in water and easy to be incorporated with other materials to form binary composites or even ternary composites. Nowadays, ternary composites have attracted enormous interest as 2 materials (binary composites) cannot satisfy the requirement of the high‐performance supercapacitor. Thus, many approaches have been employed to fabricate ternary composites by combining 3 different types of electroactive materials for high‐performance supercapacitor application. This review focuses on the supercapacitive performance of graphene‐based ternary composites with different types of active materials, ie, conducting polymers, metal oxide, and other carbon‐based materials.

“…Graphene-based hybrid materials could be prepared through covalent and non-covalent cross-linking methods [1,2], and are widely investigated in energy storage and conversion applications [3] such as supercapacitor [4], lithium ion battery [5], hydrogen storage [6], and solar cell [7]. GO-based supramolecular hydrogel has been prepared through the noncovalent interaction between triblock copolymers poly(ethylene oxide)-block-poly(propylene oxide)-block-poly-(ethylene oxide) (PEO-b-PPO-b-PEO) modified GO and a-cyclodextrin, i.e., PEO chains penetrate into the cyclodextrin cavities [8].…”

Porous graphene, which features nano-scaled pores on the sheets, is mostly investigated by computational studies. The pores on the graphene sheets may contribute to the improved mass transfer and may show potential applications in many fields. To date, the preparation of porous graphene includes chemical bottom-up approach via the aryl-aryl coupling reaction and physical preparation by high-energy techniques, and is generally conducted on substrates with limited yields. Here we show a general and scalable synthesis method for porous graphene that is developed through the carbothermal reaction between graphene and metal oxide nanoparticles produced from oxometalates or polyoxometalates. The pore formation process is observed in situ with the assistance of an electron beam. Pore engineering on graphene is conducted by controlling the pore size and/or the nitrogen doping on the porous graphene sheets by varying the amount of the oxometalates or polyoxometalates, or using ammonium-containing oxometalates or polyoxometalates.
