Scope

This document specifies the testing method for electrochemical properties such as
specific capacity, specific energy, charge-discharge efficiency, median voltage, average
voltage, discharge plateau capacity ratio, capacity retention, cycle life, and rate
capability of electrode active materials for lithium-ion batteries.
This document applies to lithium nickel-cobalt-manganate, lithium nickel-cobalt-
aluminate, lithium iron phosphate, lithium cobalt oxide, lithium manganate, lithium
nickelate, lithium nickel manganate, lithium-rich manganese-based oxide and other
positive electrode active materials as well as negative electrode active materials such
as graphite and silicon carbon negative electrode. It can also be used as a reference to
the electrochemical performance testing methods of other electrode active materials.
