This part of IEC 62607 provides a standardized method for the determination of electrochemical properties of cathode nanomaterials of, for example, lithium-ion batteries utilizing lithium iron phosphate to enable customers to: a) decide whether or not a cathode nanomaterial is usable, and b) select a cathode nanomaterial suitable for their application. This part of IEC 62607 includes: definitions of terminology used in this part of IEC 62607; recommendations for sample preparation; outlines of the experimental procedures used to measure cathode nanomaterial properties; methods of interpretation of results and discussion of data analysis, and; case studies.
