Abstract
: Lithiated graphitic carbon n.itride {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 w
quaternary C3N species to boost electronic conductivity and reversibly cycle Li ions.
