Nanostructured europium-doped layered lithium manganese oxide as a prospective cathode material for aqueous lithium-ion battery

As the world moves to greener and renewable energy generation technologies, scientific researchers are facing a great challenge of concurrently developing storage materials with low production cost, environmentally benign, high-energy density, good safety. In this work, we report on improved cycling reduced phase transformation well-studied n-Li2MnO3 achieved by doping Europium. It was established from cyclic voltammetry results that Eu-doping had stabilization effect lattice oxygen further prevented migration manganese ions previously coordinated released oxygen, into vacant octahedral site were occupied removed Li+. such, new material exhibited an increase in conductivity coulombic efficiency increased ∼74 ∼88% over 100 cycles. Moreover, discharge capacity Li2Mn0.95Eu0.05O3 4.20 mAh.g − 1 5.47 1.
