Operando monitoring of activated carbon electrodes operating with aqueous electrolytes

Prompt Thermal Transfer Across the sp3–sp2 Interfaces for the Enhanced Electrochemical Performance of Aqueous Carbon-Based Supercapacitors

“…High-resolution SECM has emerged as a valuable tool for the rapid and sensitive evaluation of electrochemical processes in different materials. , SECM offers several advantages compared to traditional nonpositional methods: (1) It allows for direct monitoring of electrochemical processes during system operation. (2) It provides experimental evidence for speculation on the origin of observed changes, avoiding post-mortem analysis . Due to the submicrometer size of the tip electrode used in SECM, it can be positioned in close proximity to the working surface of the sample, enabling the detection of electrochemical reactions that may otherwise go unnoticed.…”

Recent advances in aqueous zinc–sulfur batteries: overcoming challenges for sustainable energy storage

“…This phenomenon results in reduced ionic conductivity of the electrode, directly affecting the battery's electrochemical performance. 62,111 To address this issue, optimizing electrolyte composition, improving the cathode structure, or introducing surfactants can be employed to enhance the wettability of water molecules on the cathode surface, consequently improving battery performance.…”

Basics of the scanning electrochemical microscope and its application in the characterization of lithium-ion batteries: a brief review

“…Recently, Menzel et al reported the volume change of activated carbon electrodes in aqueous electrolytes can be characterized by SECM. 111 The SECM measurements were performed by scanning a certain part of the electrode in Li 2 SO 4 solution with K 3 Fe(CN) 6 mediator. They explained that the change in tip currents before and after electrode polarization can reflect the difference in electrode thickness.…”
