We describe the extension of a rheometer to enable in situ impedance spectroscopy and electrochemical cycling. Key advantages of this instrument over traditional flow-channel based methods for studying fluid electrodes are the possibilities to monitor the rheological properties during cycling as well as to control the mechanical history of the sample. We describe two electrochemical configurations of the instrument, allowing fluid electrodes to be studied as full and half-cells. To demonstrate the systems' capabilities, we present characterizations of 4 different fluid electrode systems.
我们描述了一种流变仪的扩展功能,使其能够进行原位阻抗谱和电化学循环。与传统的基于流动通道的研究流体电极的方法相比,该仪器的主要优点在于能够在循环过程中监测流变学特性,并控制样品的机械历史。我们描述了该仪器的两种电化学配置,可将流体电极作为全电池和半电池进行研究。为了展示该系统的能力,我们给出了4种不同流体电极系统的表征。
