摘要
钒氧化物的主要缺点作为阴极材料是它的低传导性，低实际能力和差的骑车稳定性。补充说 Cr 能改进它的传导性和一个亚稳的非结晶的状态可以提供更高的能力和稳定性。在这个工作，亚稳的非结晶的 Cr-V-O nanoparticles 成功地通过反应由退火跟随了的灵巧的一起沉淀被准备了处理。作为为锂电池的阴极材料，亚稳的非结晶的 Cr-V-O nanoparticles 展览高度能力(在在 1.54 V 之间的 100 mA/g 的 260 mAh/g ) ，低能力损失(超过 80% 在 100 mA/g 在 200 个周期以后被保留) 并且高率能力(多达 3 A/g ) 。
The main drawbacks of vanadium oxide as a cathode material are its low conductivity, low practical capacity and poor cycling stability. Adding Cr can improve its conductivity and a metastable amorphous state may provide higher capacity and stability. In this work, metastable amorphous Cr-V-O nano- particles have been successfully prepared through a facile co-precipitation reaction followed by annealing treatment. As a cathode material for lithium batteries, the metastable amorphous Cr-V-O nanoparticles exhibit high capacity （260 mAh/g at 100 mA/g between 1.5-4 V）, low capacity loss （more than 80% was retained after 200 cycles at 100 mA/g） and high rate capability （up to 3 A/g）.
