摘　　要：研究了炭化温度、升温速率以及碱处理浓度对稻壳制备锂离子电池负极材料结构及充放电性能的影响。通过差热热重分析曲线(DT-TGA)、元素分析、X射线粉末衍射(XRD)以及电化学性能测试手段对材料进行了表征。结果表明:在最佳实验条件下,材料首次充电容量为678mA.h/g,首次放电容量为239mA.h/g,循环10次的容量保持率为86.2%。In this work, the effects of carbonization temperature, heating rate and base concentration of the treatment on the structure and charge/discharge properties of secondary lithium ion battery (anode) material obtained from rice husk was investigated. The sample was analysed using differential thermal-thermogravimetric analysis (DT-TGA), element analysis, powder X-ray diffraction and other electrochemical measurements. The results showed that under the favourable experimental conditions, the first charge and discharge capacities of the material reached 678 mA·h/g and 239 mA·h/g, (respectively). Moreover, the retentive efficiency of capacity could keep up to 86.2% after ten cycles.
