Nanomanufacturing. Key control characteristics. Part 4-7. Anode nanomaterials for electric energy storage devices. Determination of the content of metal-magnetic impurities by the method of inductively coupled plasma optical emission spectrometry

This standard is part of the IEC 62607 series of standards, covers anode nanomaterials used for the manufacture of electrical energy storage devices, and specifies an inductively coupled plasma optical emission spectrometry (ICP-OES) method for determining the content of metal-magnetic impurities. This standard is used to determine the total content of metal-magnetic impurities (iron, cobalt, chromium and nickel) not less than 0.02 mg / kg.
