PD IEC TS 62607‑4‑7 is the fourth part of the multi-series international standard that focuses on nanomanufacturing and key control characteristics with nano-enabled electrical energy storage. PD IEC TS 62607‑4‑7 provides a method for the determination of magnetic impurities in anode nanomaterials for energy storage devices using an Inductively Coupled Plasma OpticalEmission Spectrometer (ICP-OES), including test overview, reagents, apparatus, test procedures, test results and test report.
PD IEC TS 62607‑4‑7 applies to the determination of the total content of magnetic impurities (iron, cobalt, chromium, and nickel) ≥ 0,02 mg/kg which can be attracted by a magnet.
PD IEC TS 62607‑4‑7 on nanomanufacturing and key control characteristics with nano-enabled electrical energy storage is useful for:
Magnetic impurities often have a significant influence on the performance of anode nanomaterials for nano-enabled electrical energy storage. If anode nanomaterials have high magnetic impurity content, it may lead to serious self-discharge and degrade the performance and cycle life. The magnetic impurities are also easy to aggregate, which can cause safety issues such as internal short-circuit fire, or even explosion. Therefore, accurate evaluation of magnetic impurity content is important for the safety and performance of energy storage devices.
PD IEC TS 62607‑4‑7 introduces a determination of magnetic impurities using the ICP-OES method for the electrochemical characterization of nano-enabled anode materials for electrical energy storage devices.
PD IEC TS 62607‑4‑7 is intended for use in comparing the characteristics of anode nanomaterials in the study stage, not for evaluating the electrode in end products.
PD IEC TS 62607‑4‑7 applies to materials exhibiting function or performance only possible with nanotechnology, intentionally added to the active materials to measurably and significantly change the reliability or one or more physical properties of electrical energy storage devices.
