基于小麦秸秆的多孔碳材料储锂性能研究
Lithium storage performance of porous carbon materials based on wheat straw
摘要
Abstract
The porous carbon materials derived from wheat straw were prepared using KOH activation-high temperature sintering methods.The structure and morphology were analyzed by scanning electron microscope(SEM),N2 adsorption/desorption test,and Raman spectrum(Raman),and the application in lithium-ion battery was investigated by galvanostatic charge/discharge(GCD)and cyclic voltammetry(CV)techniques.The findings demonstrated that the carbon material prepared by using 10 mol·L-1 KOH as activator can retain a specific capacity of 348.4 mAh·g-1 following 100 cycles,with a specific capacity as high as 431.2 mAh·g-1 when the current density is increased to 3.5 A·g-1,exhibiting an enhanced rate performance.This is attributed to more microporous voids and higher disorder of the material,which provide more electrochemically active sites.关键词
