硬炭微球/MXene柔性薄膜负极应用于高性能钠离子存储
A flexible hard carbon microsphere/MXene film as a high-perform-ance anode for sodium-ion storage
摘要
Abstract
Hard carbon is considered the most promising anode material for sodium-ion batteries,but its volume change during sodiation/desodiation limits its cycle life.Hard carbon microspheres(HCSs)with no binder were composited with a MXene film to form an electrode and its sodium storage properties were studied.The microspheres were prepared using Shanxi aged vinegar as a li-quid carbon source.Two-dimensional Ti3C2Tx MXene(T is a functional group)was used as a multifunctional conductive binder to fabricate the flexible electrodes.Remarkably,because of the three-dimensional conductive network,the HCS/Ti3C2Tx film electrode has a high capacity of 346 mAh g-1,excellent rate performance and outstanding cycling stability over 1 000 cycles.This remarkable electrochemical performance indicates that the flexible film is a very promising anode for next-generation sodium-ion batteries.关键词
