Defects in carbon-based materials can be categorised as either intrinsic or non-intrinsic (also referred to as doping defects). 23, 24 Intrinsic defects include those induced within the carbon lattice, such as lattice distortions, carbon vacancies, and edge defects (such as zigzag and armchair edges).
Defect engineering could modulate the structures of carbon materials, thereby affecting their electronic properties. The presence of defects on carbons may lead to asymmetric charge distribution, change in geometrical configuration, and distortion of the electronic structure that may result in unexpected electrochemical performances.
Generally speaking, according to the nature of crystal defect engineering, the main roles of defects in energy storage and conversion systems can be summarized as follows ( Fig. 12 ): (I) Crystal defects can be exploited as energy storage/adsorption/active/nucleation sites.
The quantity and type of defects strongly depend on the method used. In subtractive methods, the oxidation reaction of the carbon is utilised to form volatile compounds, causing the carbon structure to form intrinsic defects, i. e ., edge sites, vacancies, grain boundaries, dislocations, cracks and void defects.
[ 16] “Defect engineering” refers to the goal-directed control of the type, concentration, configuration, and spatial distribution of defect to tailor the electrochemical properties of carbon materials. The incorporation of defects on carbons allows for tuning their surface structures and intrinsic properties.
Correspondingly, defect engineering, that is creating defects on carbons, become an efficient strategy to change the electrochemical performances of carbon materials by tuning their local electronic structures, surface morphology, and charge redistribution.
