摘要/Abstract

摘要：以SnCl₄·5H₂O、Cu(NO₃)₂·3H₂O和NH₃·H₂O为原料，采用化学共沉淀法制备了CuO掺杂的纳米SnO₂粉末.运用X射线衍射、扫描电镜等手段对合成粉末进行了表征.将合成粉末作为锂离子电池负极材料，研究了其充放电容量、循环性能和交流阻抗等电化学性能.结果表明：采用化学共沉淀法可以得到平均粒度为87 nm的CuO掺杂的纳米SnO₂粉末；在SnO2中掺入CuO，并没有改变SnO₂的结构，但能够有效抑制SnO₂粒子的长大；CuO掺杂的纳米SnO₂粉末的可逆容量可以达到752 mA·g^-1，经60次循环后，CuO掺杂的纳米SnO₂粉末的容量保持率分别为93.6%，优于纳米SnO₂(92.0%)，掺杂CuO改善了纳米SnO₂的循环性能.

Abstract: CuO-doped nano-SnO₂ powders were prepared by chemical coprecipitation method using SnCl₄·5H₂O,NH₃·H₂O,and Cu(NO₃)₂·3H₂O as raw materials.The powders were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM).The electrochemical properties of CuO-doped nano-SnO₂ powders and undoped SnO₂ powders as anode materials of lithium ion batteries were investigated comparatively by charge-discharge curves,cyclability and AC impedance.Results show that SnO₂ -CuO nano composite powders with average particle size of 87 nm could be obtained through chemical coprecipitation method.The structure of SnO₂ was not changed,but the average particle size of nano-SnO₂ decreased due to the introduction of CuO.CuO-doped nano-SnO₂ powders show a reversible capacity of 752 mA·g^-1 and better cyclability compared with undoped nano-SnO₂ .The capacity retention rate of undoped nano-SnO₂ and CuO-doped nano-SnO2 powders is 93.6% and 92.0% at 0.1 C rate,respectively,which suggests that introduction of CuO in SnO₂ can improve the cyclability of nano-SnO₂ .
