提出了一种新的基于非对称交叉指阵（IDA）的电分析设计，并从电化学角度表征了非对称对器件性能的影响。相互独立地改变集电极和发生器的频带宽度可以调节收集效率和氧化还原循环引起的反馈。这些阵列能够提供低反馈（< 10%），同时保持中等收集效率（25%-40%）。通过实验和数值模型对其性能进行了评价。演示了该装置在非水锂离子和钠离子电池电解质中可溶电解质降解产物检测中的应用。
A new electroanalytical design based on asymmetric interdigitated arrays (IDA) is presented and the effects of asymmetry on the device performance are characterized electrochemically. Varying the collector and generator band widths independently of each other tunes the collection efficiency and redox cycling-induced feedback. These arrays are able to provide low feedback (< 10%) while maintaining moderate collection efficiency (25%–40%). Behavior is evaluated experimentally and using a numerical model. The application of the device to detect soluble electrolyte degradation products in nonaqueous lithium-ion and sodium-ion battery electrolytes is demonstrated.
