采用溶剂热合成法制备了形状均匀的WO2.72纳米线束。他们研究了WO2.72纳米线束用作电致变色器件阴极的潜力以及Li+插入（或提取）动力学和Li+扩散的影响。形成由WO2.72纳米线束的阵列组成的电极，并将其用于使用Langmuir-Blodgett技术的实验中。WO2.72的一维纳米结构具有高的锂离子扩散系数（~ 5.2×10 - 11 cm 2 scins）和低的电荷转移电阻（~ 28.6Ω），这导致其具有快速的电致变色响应时间（显色时间55 cm 2 scinC）。
The authors prepared uniformly shaped WO2.72 nanowire bundles using the solvothermal synthesis method. They investigated the potential of the WO2.72 nanowire bundles to be used as a cathode electrode for electrochromic devices and the effect of the Li+ insertion (or extraction) kinetics and diffusion of Li+. An electrode consisting of arrays of WO2.72 nanowire bundles was formed and used in an experiment using the Langmuir-Blodgett technique. The one-dimensional nanostructure of WO2.72 has a high Li-ion diffusion coefficient (∼5.2×10−11cm2∕s) and low charge transfer resistance (∼28.6Ω), which result in its having a fast electrochromic response time (coloring time 55cm2∕C).
