Graphitic domains
WebJan 29, 2024 · F-doping hard carbon (F–HC) was synthesized through a mild fluorination at temperature at relative low temperature as the potential anode for sodium-ion batteries (SIBs). The F-doping treatment to HC expands interlayer distance and creates some defects in the graphitic framework, which has the ability to improve Na+ storage capability … WebFeb 25, 2014 · The H 2 SO 4 molecules must still be intercalated between the graphene layers within the graphitic domains. The interlayer distance (d i d i = 7.98 A°) is likely due to insertion of oxygen atoms within the oxidized domains in addition to the existing sulfuric acid molecules. The oxidized domains with irregular structure might only be ...
