将锂化氧化铜纳米棒作为锗负极集流体的纳米结构电子导体，以提高锂离子电池的性能。通过将电压截止窗口限制在可以避免初始放电后CuO的放电-充电平台的范围内，锂化的CuO纳米棒可以充当电子导体。所获得的Ge阳极表现出优异的倍率性能和上级循环性能。在1A/g的电流密度下，即使在100次循环后，阳极仍呈现出高于95%的容量保持率。即使在高达10 A/g的电流密度下，阳极也表现出稳定的倍率性能。这种增强的性能可以主要归因于锂化的CuO纳米棒，其可以导致纳米电缆结构，该纳米电缆结构提供短的电子/锂离子传输路径、足够的缓冲空间用于Ge涂层的巨大体积变化以及Ge涂层与集流体之间的良好电接触。
Lithiated-CuO nanorods were used as a nanostructured electronic-conductor of the current-collector for Ge anode to improve the performance of lithium-ion batteries. By limiting the voltage cut-off window in a range which could avoid the discharge–charge plateaus of CuO after the initial discharge, the lithiated-CuO nanorods can act as an electronic-conductor. The obtained Ge anode exhibits an excellent rate capability and superior cyclability. At a current-density of 1 A/g, the anode presents a capacity retention of above 95% even after 100 cycles. The anode also presents a stable rate performance even at a current-density as high as 10 A/g. The enhanced performance can be mainly ascribed to the lithiated-CuO nanorods which could result in a nanocable structure that offers short electron/lithium-ion transport path, enough buffering space for the huge volume change of Ge coating and excellent electrical contact between the Ge coating and the current-collector.
