The drafting explanation for a proposed method to analyse magnetic metallic contaminants in lithium-ion battery cathode and anode materials records a CABIA project review on 29 November 2021. It discusses analytical approaches including inductively coupled plasma optical emission spectrometry, scanning electron microscopy and energy-dispersive spectroscopy, alongside particle morphology and size information. This is a historical resource on the development of materials-quality methods. The available document is a drafting explanation, not evidence of a final issued standard; no final number, issue date or current validity is asserted.
