摘要：

A graphene-coated polymer separator was developed for lithium-selenium batteries with pure selenium powder as the active material. The structure is a simple yet effective strategy for improving Li-Se battery's electrochemical performance, yielding long cycle life up to 1000 cycles with high capacity and excellent rate behavior.
