New materials for batteries like cathode, anode and electrolyte materials, but also commercially available batteries, need to be electrochemically evaluated. This can be done using a variety of techniques like Cyclic Voltammetry (CV), Electrical Impedance Spectroscopy (EIS) or Galvanostatic and Potentiostatic discharging & charging (Cycling). For example, rechargeable Li-ion, Li-air, or Na-ion batteries can be cycled using programmable battery testers with tens of independent test channels to analyse the storage capacity, the capacity retention, fading mechanisms or the performance as a function of temperature and current density. Combining these electrochemical measurements with structural and chemical analysis tools, like diffraction and spectroscopy, enables the development of storage materials with higher energy density, longer life or faster charge rates.
