Research activity on ceramic/graphene composites and hybrids has increased dramatically in the last decade. In this review, we provide an overview of recent contributions involving ceramics, graphene, and graphene-related materials (GRM, i.e., graphene oxide, reduced graphene oxide, and graphene nanoplatelets) with a primary focus on applications. We have adopted a broad scope of the term ceramics, therefore including some applications of GRM with certain metal oxides and cement-based matrices in the review. Applications of ceramic/graphene hybrids and composites cover many different areas, in particular, energy production and storage (batteries, supercapacitors, solar and fuel cells), energy harvesting, sensors and biosensors, electromagnetic interference shielding, biomaterials, thermal management (heat dissipation and heat conduction functions), engineering components, catalysts, etc. A section on ceramic/GRM composites processed by additive manufacturing methods is included due to their industrial potential and waste reduction capability. All these applications of ceramic/graphene composites and hybrids are listed and mentioned in the present review, ending with the authors’ outlook of those that seem most promising, based on the research efforts carried out in this field.

“…This achieved conductivity with GO is much higher to than our early reported anode for low‐temperature SOFC application 60 . Abbas et al 55,61 reported conductivity 6.15 and 4.15 S/cm for the BCFZ (Ba 0.05 Cu 0.25 Fe 0.10 Zn 0.60 O) electrode and Cu 0.16 Ni 0.27 Zn 0.37 Ce 0.16 Gd 0.04 anode respectively in the hydrogen atmosphere. The conductivity measurements obtained in our present anode composite are even higher to referred conductivity value of NiCu anode materials 44,62 …”

“…The Al 0.1 Ni 0.2 Zn 0.7 nanocomposite produced the highest conductivity and power density of 0.53 S cm À1 and 375 mW cm À2 at 370 1C and 600 1C, respectively, with 1.3% graphene coated on the anode materials. 37 The current study of the graphene-based nanocomposite La 0.6 Sr 0.4 Al 0.2 Cu 0.8 O 3 -graphene is a primary piece of evidence for utilizing graphene-fused anode materials for energy transformation devices (SOFCs). The reason for using a graphene-based nanocomposite is to decrease the working temperature of the SOFC without compromising its performance.…”
