"nitrile electrolyte additive, tridentate ligand-containing 1,3,6-hexanetricarbonitrile... far outperforming... electron microscopy... HTCN additive inhibiting generation cracks and dissolution of cobalt ions... adsorbed to)  LCO and embedded in interface between cathode and electrolyte... inhibit oxidation reaction on surface... suppressed decomposition of components and formation of cracks... enhances the stability of the battery through a great many cycles of charging and discharging"
