光谱电化学 (SEC) 能够对电化学电池进行操作中紫外可见光研究，以探索不同电池组件的演变并了解电池机制。研究人员已经展示了各种定制的紫外可见光池设计，以适应 SEC 实验。然而，现有的设计不容易允许温度斜坡技术来检查快速变化的电池温度或高温条件对电池机制的影响。本次交流介绍了两种易于复制、低成本的池设计，它们可与现有的紫外可见系统（透射率、反射率）相结合，并可实现高温、快速加热 SEC 实验。每个电池设计都经过测试，以评估温度斜坡和密封性能。
Spectroelectrochemistry (SEC) enables in-operando UV–vis study of electrochemical cells to explore the evolution of different cell components and understand cell mechanisms. Researchers have demonstrated various custom UV–vis cell designs to accommodate SEC experiments. However, existing designs do not easily permit temperature ramp techniques to examine the effects of rapidly changing cell temperature or high temperature conditions on cell mechanisms. This communication presents two easy-to-replicate, low-cost cell designs that are incorporable with existing UV–vis systems (transmittance, reflectance) and enable high temperature, rapid heating SEC experiments. Each cell design was tested to evaluate temperature ramp and sealing performance.
