Abstract In this work, we focus on Mg–Fe–O and Mg–Ni–O with Mg-rich compositions as positive-electrode materials for magnesium rechargeable batteries, and prepare them by a thermal decomposition of precipitates obtained by a solution method.

It is widely recognized that heat-resistant separators improve the safety of lithium-ion batteries. However, it is not clear how the separator contributes to battery safety, or how much heat resistance is required. The state of separators when a shor
