The electrochemical window measurement methods of liquid and solid electrolytes are suggested. The availability of solid electrolytes promisingly boosts the energy density of lithium-ion batteries (LIBs), yet the accurate voltammetry measurement of their electrochemical windows (EWs) poses a longstanding and critical concern.
There are a variety of voltammetric methods. This unit will only explore three of these methods: anodic stripping voltammetry (ASV), linear sweep voltammetry, and cyclic voltammetry (CV). Voltammetric methods typically involve the use of microelectrodes that frequently have areas on the order of 0.3-10 cm2.
These studies reveal that EW measurement of solid electrolytes by voltammetry methods is not standard, and the use of different scan modes or working electrodes often yields different results, which hinders the development of solid electrolytes.
Analyte cations that are in the solution and away from the surface of the electrode will be shielded from the charge on the electrode by all the K+ ions in between. Samples subjected to voltammetric methods are usually purged with nitrogen or other inert gas before the analysis and maintained under an inert atmosphere during the analysis.
Voltammetry is the most commonly used method to measure the EW of electrolytes. Typically, lithium is used as the counter electrode, and SS, carbon, or other inert materials that cannot store lithium serves as the working electrode.
Herein, we demonstrate how cyclic voltammetry (CV), a well-known technique to the battery community, can be used differently as an elegant tool to rapidly provide qualitative and quantitative insights about the thermodynamics and kinetics of the reaction processes associated to each additive, hence enhancing the confection of new electrolytes.
