Holey Graphene (hG) represents a cutting-edge advancement in energy storage materials, characterized by the introduction of nanoengineered holes into traditional graphene sheets. This novel alteration grants hG remarkable dry compressibility at ambient conditions and bolsters graphene layer cohesion, enabling the development of thicker electrodes devoid of binders. Such attributes culminate in batteries boasting heightened resilience, longevity, and improved shock durability. Utilizing a pioneering dry-press method, hG supports ultrahigh mass loading cathodes, driving superior cell and pack efficiencies. This allotrope provides an excellent scaffolding for solvent-free doping of graphene sheets for a wide range of applications. Additionally, the strategically placed nanoholes serve to drastically augment the available surface area, translating to an impressive boost in areal capacity—vital for optimizing both batteries and supercapacitors. Moreover, the adaptability of hG extends to its role in the creation of supercapacitors, hybrid energy storage devices, and high-quality graphene films. With facile doping capabilities and its affinity with a simplified manufacturing regimen, Holey Graphene is poised to reshape the future landscape of energy storage, heralding a new era for advanced batteries and supercapacitors.
