摘要：

A P2-layered oxide using copper as the active redox metal has been discovered. It has a composition of Na2/3Cu1/3Mn2/3O2, and can withstand a thousand cycles, maintaining 61% of its original capacity. We demonstrate that copper can enable not only high voltage, but also excellent stability. This work opens up a new avenue of oxide design for high energy, cost effective battery systems.
