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:<\/p>\n
decide whether or not a cathode nanomaterial is usable, and<\/p>\n<\/li>\n
select a cathode nanomaterial suitable for their application.<\/p>\n<\/li>\n<\/ol>\n
This part of IEC 62607 includes:<\/p>\n
definitions of terminology used in this part of IEC 62607,<\/p>\n<\/li>\n
recommendations for sample preparation,<\/p>\n<\/li>\n
outlines of the experimental procedures used to measure cathode nanomaterial properties,<\/p>\n<\/li>\n
methods of interpretation of results and discussion of data analysis, and case studies.<\/p>\n<\/li>\n<\/ul>\n
