Conventional Three-Electrode Cell Design and Fabrication

1 Conventional Three-Electrode Cell Design and Fabrication 

To prepare the working electrode layer, the electrode active material such as carbon or pseudocapacitive materials are mixed with conductive carbon and isopropanol for 30 to 60 min to form an ink. A desired amount of this ink (several microliters for a small electrode surface area such as 0.2 to 0.5 cm ) is pipetted gradually onto a prepolished electrode with a microsyringe. After drying, several microliters of diluted Nation solution is used to cover the coated electrode to form a uniform electrode layer for electrochemical measurements.
