Abstract Environmentally sustainable, low\u2010cost, flexible, and lightweight energy storage technologies require advancement in materials design in order to obtain more efficient organic metal\u2010ion batteries. Synthetically tailored organic molecules, which react reversibly with lithium, may address the need for cost\u2010effective and eco\u2010friendly anodes used for organic\/lithium battery technologies. Among them, carboxylic group\u2010bearing molecules act as high\u2010energy content anodes. Although organic molecules offer rich chemistry, allowing a high content of carboxyl groups to be installed on aromatic rings, they suffer from low conductivity and leakage to the electrolytes, which restricts their actual capacity, the charging\/discharging rate, and eventually their application potential. Here, a densely carboxylated but conducting graphene derivative (graphene acid (GA)) is designed to circumvent these critical limitations, enabling effective operation without compromising the mechanical or chemical stability of the electrode. Experiments including operando Raman measurements and theoretical calculations reveal the excellent charge transport, redox activity, and lithium intercalation properties of the GA anode at the single\u2010layer level, outperforming all reported organic anodes, including commercial monolayer graphene and graphene nanoplatelets. The practical capacity and rate capability of 800 mAh g \u22121 at 0.05 A g \u22121 and 174 mAh g \u22121 at 2.0 A g \u22121 demonstrate the true potential of GA anodes in advanced lithium\u2010ion batteries.<\/p>\n","protected":false},"excerpt":{"rendered":"
