DIN IEC/TS 62607-4-5:2016-08 - Draft

This part of IEC 62607 specifies a standardized methodology for characterizing the electrochemical properties of new cathode nanomaterials used in electrical energy storage devices. This methodology allows comparison of different types of cathode nanomaterials and comparison of results from different research groups. This part of IEC 62607 specifies a 3-electrode cell method for the electrochemical characterization of nano-based cathode materials for electrical energy storage devices. This standardized method is intended for use in comparing the properties of cathode nanomaterials in the development phase, not for evaluating the electrode in the final product. The method is applicable to materials that exhibit a function or performance made possible only by nanotechnology and that is intentionally added to the active material to measurably and significantly change the capacity of the electrical energy storage devices. In this context it is important to note that the percentage of nanomaterial in the device in question is not directly related to the applicability of this part of IEC 62607, as often minute amounts of nanomaterial are sufficient to significantly improve performance. The percentage of nanomaterials in electrodes, electrode coatings, separators or electrolyte is not relevant to the application of this procedure. The responsible committee is DKE/K 141 "Nanotechnologie" ("Nanotechnology") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
