Publication: Carbon Surface Functionalities and SEI Formation During Li Intercalation

This review aims to (1) briefly summarize the use of carbon as intercalation materials in
electrochemical energy storage and the development of the solid electrolyte interphase
(SEI) layer on the surface of the carbon electrode, (2) discuss the impacts of surface functional
groups on the physical and electronic properties of carbon materials and the performance
of electrochemical energy storage devices, (3) analyze the specific contributions that
the most abundant oxygen and nitrogen carbon-surface functionality, in particular surface
functional group hybridization and the influence that Lewis basicity/acidity, have towards
promoting Li-ion charge storage and (4) examine the impact that those heteroatom functionalities
have on the formation of the SEI layer.
