Waste-induced pyrolytic carbon nanotube forest as a catalytic host electrode for high-performance aluminum metal anodes

Aluminum dendrite suppression by graphite coated anodes of Al-metal batteries

“…These results indicate that the graphite coating layer greatly impacts the plating/stripping behaviours and improves the electrochemical reversibility of the Al anode. The electrochemical performances of state-of-the-art Al anodes are listed in Table S1 † 10,22,37,39–44 . It is found that our Al-g anode shows competitive electrochemical performances.…”

Defect engineering in carbon materials for electrochemical energy storage and catalytic conversion

“…The researchers revealed a strong positive correlation between the level of intrinsic defects and the capacity/capacity retention, while the wettability of the carbon materials increased with the increase of the defect concentration, resulting in the rapid penetration of electrolyte ions. Furthermore, Ha et al 194 calculated the binding energy of the perfect graphene model and topological defect model (C 585 , C 55777 ) to Al 2 Cl 7 − and Al. The results show a forceful interaction between Al ions and defective carbon sites, and the defect sites are conducive to reducing Al 3+ to Al atoms through electron transfer on the electrode surface (Fig.…”

Structure-oriented conversions of plastics to carbon nanomaterials

“… Kong and Zhang 2007 ; Pol and Thackeray 2011 One-pot The one-pot method is facile to produce CNTs but unsuitable for scale-up production. Gong et al 2013d , Gong et al 2013a , Gong et al 2012a ; Ha et al 2022 Atmosphere The carbonization is usually conducted at an inert atmosphere (nitrogen or argon). Hydrogen atmosphere was applied to reduce catalyst precursors to metal catalysts, which will facilitate the formation of CNTs.…”
