Approaching the lithium-manganese oxides' energy storage limit with Li2MnO3 nanorods for high-performance supercapacitor

Lithium manganese oxides are of great interest due to their high theoretical specific capacity for electrochemical energy storage. However, it is still a big challenge to approach its large theoretical limit. In this work, we report that Li2MnO3 nanorods with layered structure as superior performance electrode for supercapacitors. The synthesized Li2MnO3 nanorods possess large specific surface area of 179.5 m2/g. The electrode made of the...
