针状焦改性作为锂离子电池负极材料的研究
Research of needle coke modified anode materials for lithium-ion battery
摘要
Abstract
Carbon coating followed by H2 reduction was used to improve electrochemical properties of calcined needle coke using as lithium ion battery (LIB) anode material.Needle coke were calcined in N2 at 750,900,1 300,1 500,2 000 and 2 200 ℃C,respectively.The carbon precursor for coating is an amphiphilic carbonaceous material oxidized from coal tar pitch.Scanning electron microscopy (SEM),X-ray diffraction patterns (XRD) and galvanostatic charge/discharge were carried out for the characterization of the resulted samples.NC@C-H900 sample of 3-10 μm in size has an average charge specific capacity of 357.9 mAh/g at 0.1 C (37.2 mA/g).Carbon coating and H2 reduction improve the sample's initial coulomb efficiency,rate performance and cycle stability.关键词
