本文介绍了一种低成本USB控制的恒电位仪/恒电流仪的设计，该恒电位仪/恒电流仪可以测量或施加+/- 8 V范围内的电位，测量或施加从纳安到最大值的电流。+/- 25 mA。板载20位D/A转换器和22位A/D转换器使精度非常高。双控制模式及其广泛的电位范围使其特别适合电池表征。作为一个示例用例，在使用薄膜TiO 2作为工作电极的锂离子测试电池上进行测量。跨平台Python程序可用于在易于使用的图形用户界面内运行电化学实验。采用开放硬件理念并使用开源工具进行设计，项目的所有细节（包括原理图、PCB设计、微控制器固件和主机软件）都可以免费获得，使设计的自定义修改变得简单。(C)2017作者爱思唯尔有限公司出版
This article describes the design of a low-cost USB-controlled potentiostat/galvanostat which can measure or apply potentials in the range of +/- 8 V, and measure or apply currents ranging from nanoamps to max. +/- 25 mA. Precision is excellent thanks to the on-board 20-bit D/A-convertor and 22-bit A/D-convertors. The dual control modes and its wide potential range make it especially suitable for battery characterization. As an example use case, measurements are presented on a lithium-ion test cell using thin-film anatase TiO2 as the working electrode. A cross-platform Python program may be used to run electrochemical experiments within an easy-to-use graphical user interface. Designed with an open hardware philosophy and using open-source tools, all the details of the project (including the schematic, PCB design, microcontroller firmware, and host computer software) are freely available, making custom modifications of the design straightforward.
