Abstract

Lithiated graphitic carbon nitride (C₃N₄) was fabricated by electrochemical and solid-state reactions. The addition of Li to C₃N₄ results in a reaction between the Li and the graphite-like C₃N species in C₃N₄. This irreversible reaction leads to the formation of Li-CH=NR and Li-N=CR₂ species, which are detrimental to anode properties. Suitable nitrogen-doped carbon structures for anode applications are predicted to need high concentrations of pyridinic C-N-C terminal bonds and low concentrations of quaternary C₃N species to boost electronic conductivity and reversibly cycle Li ions.
