Abstract (en)

[origin: WO2022076251A1] Articles and methods related to electrochemical cells and/or electrochemical cell components (such as electrodes and/or electrolytes) comprising species comprising a conjugated, negatively-charged ring comprising a nitrogen atom and/or reaction products of such species are generally provided. The electrochemical cell may comprise an electrode (e.g., a cathode and/or an anode) comprising a protective layer comprising a species comprising a conjugated, negatively-charged ring comprising a nitrogen atom and/or a reaction product thereof. The electrochemical cell may comprise an electrolyte comprising a species comprising a conjugated, negatively-charged ring comprising a nitrogen atom and/or a reaction product thereof.
