Abstract
A system for analyzing foreign substances in a positive electrode material, includes a pretreatment part configured to prepare a monolayer sample of a positive electrode material powder, a measurement part configured to obtain an optical image of the monolayer sample using an optical microscope, and an analysis part configured to analyze the optical image of the monolayer sample and obtain information on foreign substances in the positive electrode material. Also provided is a method for analyzing metallic foreign substances in a positive electrode material.
Claims46
A system for analyzing metallic foreign substances in a positive electrode material, comprising:
- a pretreatment part configured to prepare a monolayer sample of a positive electrode material powder;
- a measurement part configured to obtain an optical image of the monolayer sample using an optical microscope;
- and
- an analysis part configured to analyze the optical image of the monolayer sample, thereby obtaining information on foreign substances in a positive electrode material;
- wherein the pretreatment part comprises a substrate on which the positive electrode material powder is applied and a first member configured to remove a portion of the positive electrode material powder applied on the substrate to allow positive electrode material particles to be distributed in a monolayer.
