Abstract: Embodiments relate generally to systems and methods for identifying the concentration of an electrolyte. A method may comprise scanning a working electrode of an electrochemical sensor using cyclic voltammetry at a plurality of electrolyte concentrations; generating a variable set of readings from the first cyclic voltammetry scan using a potential difference between a hydrogen adsorption peak and a Pt-Oxide reduction peak at each of the plurality of electrolyte concentrations; and determining a correlation by plotting the variable set of readings and the plurality of electrolyte concentrations. In some embodiments, the method may comprise scanning a working electrode of a second electrochemical sensor using cyclic voltammetry, wherein the second electrochemical sensor has been employed; generating a second set of readings; and determining the electrolyte concentration of the electrolyte of the second electrochemical sensor by applying the determined correlation to the second set of readings.

Abstract: An electrochemical cell for testing the electrochemical behavior of a plurality of materials comprises: a first electrode; a counter-electrode bearing an electrochromic material having a visual or measurable property which changes in a manner proportional to the total charge passed through it; and an electrolyte between and in electrical contact with the first electrode and the counter-electrode; wherein one of the first electrode and the electrolyte comprises a plurality of regions, each region comprising a sample of material to be tested, the regions being, in the case of the first electrode, electrically connected to a common terminal. Such a cell can be used for a “combinatorial chemistry” approach to testing the properties of possible cell components.
