In addition to the input voltage range, input frequency plays a significant role in determining the potential applications of iontronic devices. Unlike electronic devices, which can operate at high frequencies reaching the megahertz (MHz) range, iontronic devices are limited in frequency due to their electrochemical nature. In electronic devices, the flow of electrons is significantly faster than the flow of ions in iontronic devices, while ions require more time to complete electrochemical interactions or form an EDL. Consequently, iontronic devices typically operate at lower frequencies. Previous studies have shown promising results for simple logic gates operating at low frequencies, such as 10 mHz to 50 mHz, which restricts their application to low-frequency fields. However, this study extends the capabilities of iontronic devices by demonstrating performance at higher frequencies, reaching up to 1000 mHz, a significant milestone in the field. Overall, this investigation, along with further measurements, proves that the device can maintain the characteristic functions of electronic diodes while also exhibiting the energy storage capabilities of ECs. The results suggest that iontronic devices can offer broad switching capabilities and meet the requirements for various applications where traditional electronic devices may be limited.
