Metal oxide anode material is one of promising candidates for the next-generation LIBs, due to its high theoretical capacity and low cost. The poor conductivity and huge volume change during charge/ discharge, however, restrict the commercialization of metal oxide anode material. In this work, we design a novel Cu-SnO2 composite derived from Cu6Sn5 alloy with three dimensional （3D） metal cluster conducting architecture. The novel Cu structure penetrates in the composite particles inducing high conductivity and space-confined SnO2, which restrict the pulverization of SnO2 during lithiation/ delithiation process. The optimized Cu-SnO2 composite anode delivers an initial discharge capacity of 933.7 mA h/g and retains a capacity of 536.1 mA h/g after 200 cycles, at 25℃ and a rate of 100 mA/g. Even at the high rate of 300 mA/g, the anode still exhibits a capacity of more than 29% of that tested at 50 mA/g. Combining with the phase and morphology analysis, the novel Cu-SnO2 composite not only has good electrical conductivity, but also possesses high theoretical capacity （995 mAh/g）, which may pave a new way for the design and construction of next-generation metal oxide anode materials with high power and cycling stability.

为及时识别发电机驱动端轴承的异常运行状态,利用风电机组数据采集与监视控制(SCADA)系统参数序列之间存在的内在相关性,提出一种基于协整和向量误差修正模型的发电机驱动端轴承异常识别方法。首先,对所选温度SCADA参数序列的平稳性进行检验,分析各参数的单整阶数;然后,通过协整检验来确定所选参数之间的长期均衡关系;最后,在协整关系的基础上构建适用于温度SCADA参数的向量误差修正模型,计算模型预测残差的均方根误差,使用指数加权移动平均值设定阈值对发电机驱动端轴承的运行状态进行监测。利用内蒙古某风场的一组发电机驱动端轴承故障数据进行验证,结果表明该方法能有效识别发电机驱动端轴承的异常状态,及时发现早期故障。
