A Se/C composite as cathode material for rechargeable lithium batteries with good electrochemical performance

Abstract

A Se/C composite was prepared by a simple combination method of ball milling and low temperature treatment as a cathode material for Li–Se rechargeable batteries. It was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Its electrochemical performance as a cathode material for lithium rechargeable batteries was tested by cyclic voltammetry (CV) and capacity measurements. Rate capacity and cycling performance of the as-prepared product are very satisfactory. Even at a current density of 500 mA g−1, the composite can deliver a capacity of 187 mA h g−1. The main reason is that the high conductivity of carbon decreases its charge transfer resistance and effectively suppresses the dissolution of oxidation products from the composite cathode.
