Electrochemical efficacies of coal derived nanocarbons

Dec 6, 2020Anthracite is the best quality coal, consisting 92%-98% of carbon with fewer impurities, followed by bituminous, sub-bituminous coal and lignite. More carbon content in the coal is an implication of larger carbon clusters available for the extraction of nanocarbon derivatives (Saikia et al. 2009; Meng et al. 2019 ).

Anthracite For The Production Of Batteries: Casings And Anodes

Anthracite has a density of 1.3 to 1.8 g/cm 3, which is less than carbon black and less than half that of aluminium oxide - making it a good choice even before considering other advantages (3). Utilising low-density anthracite can substantially bring down battery weight, compared to an average density across all common fillers of 2.6 to 2.9 g/cm 3.
