Heteroatom incorporated coke for electrochemical cell electrode
Patent
·
OSTI ID:512419
This invention relates to an electrode for a coke/alkali metal electrochemical cell comprising: (a) calcined coke particles: (1) that contain at least 0.5 weight percent of nitrogen heteroatoms and at least 1.0 weight percent sulfur heteroatoms, and (2) that have an average particle size from 2 microns to 40 microns with essentially no particles being greater than 50 microns and (b) a binder. This invention also relates to a coke/alkali metal electrochemical cell comprising: (a) an electrode as described above, (b) a non-aqueous electrolytic solution comprising an organic aprotic solvent and an electrically conductive salt, and (c) a counterelectrode. 5 figs.
