Abstract:Rapid capacity fading and sluggish diffusion kinetics resulting from crystal conversion/powder pulverization hinder practical energy storage application of conversion-type electrodes. To address this issue, we prepared a Cu2S/polyelectrolyte/graphene composite (denoted as Cu2S/PG) through interfacial optimization by incorporating a polyelectrolyte to enhance the connection between Cu2S powders and N-doped graphene. In comparison to CuS and Cu2S, the electrochemical performance of Cu2S/PG was significantly impr… Show more
