AI Technical Summary
Traditional lithium-ion battery anode materials, such as metal selenides, suffer from volume expansion and low conductivity, resulting in poor capacity and short cycle life. Existing synthesis methods are complex and time-consuming.
Metal selenide/carbon composite electrode materials were prepared by electrospinning combined with a two-step calcination process. The carbon nanofiber network structure was formed by electrospinning, and metal selenide nanoparticles were uniformly dispersed on its surface, which simplified the synthesis process and improved the conductivity.
We have achieved efficient preparation of metal selenide/carbon composite materials with good conductivity and stable cycle performance, which improves the rate performance and cycle life of lithium-ion batteries.
