Abstract
A method for determining an amount of lithium in a lithium-ion battery electrode sample includes a step of determining powder X-ray diffraction peaks of the lithium-ion battery electrode sample. The powder X-ray diffraction peaks of the lithium-ion battery electrode sample are compared with a set of lithium-containing samples having pre-determined lithium concentrations to determine the amount of lithium in the lithium-ion battery electrode sample.
