Enhancement of electrochemical performance of lithium manganese oxide with graphene for aqueous supercapabattery

In this study, we synthesized lithium manganese oxide nanoparticles/graphene nanoplatelets (LMO/GNPs) as the cathode material for a supercapabattery using a hydrothermal method. The addition of GNPs resulted in a 63 and 68 increase in specific capacitance and capacity compared to LMO alone, attribut...
