Reproducibly Defining Electrode Area of Carbon Paper Electrodes via Machine Cutting and High-Throughput Waxing

Carbon paper is one of the most common carbon electrode materials employed in electrochemical research due to its low cost, disposability, and controllable dimensions scaling. usually hand cut a variety strategies are used define area. This procedure tedious, imprecise, inaccurate, yielding coefficients variation peak current output as high 20%. Imprecision hand-preparation translates directly poor reproducibility data leading challenges comparing across groups fields. work introduces an inexpensive precise method automatically rapidly wax electrodes, circumventing laborious traditional preparation substantially improving precision data.
