Electrochemistry – Ideal for Studying the Performance of Batteries and Battery Materials The specially designed potentiostats/galvanostats from Metrohm are employed for the characterization of battery raw materials, in addition to finished batteries. Electrochemical measurements are based on highly accurate control and measurements of electrical charge, voltage, impedance, or current. Voltammetry is a highly sensitive technique that has LODs in the ppb range. It can be utilized for the analysis of electrochemically active substances, like organic or inorganic ions. For instance, voltammetry enables the simultaneous determination of cobalt, nickel, and manganese in cathode materials. This method can be combined with a large variety of applications and has short analysis times and high precision with comparatively low costs of the instrumentation required.
