Robust and durable Li-ion batteries fabricated using lead-free crystalline M₂NiMnO₆ (where M = Eu, Gd, and Tb) double perovskites

Abstract

Double perovskites with the general formula A2B1B2O6, in which A2 is a lanthanide or alkaline earth metal and B1 and B2 are transition metals, are famous for their structures and excellent chemical and physical properties.
