The materialographic investigation of anode materials for rechargeable lithium ion batteries is a significant step in the understanding and development of electrode materials, but made dramatically more difficult due to the high reactivity of the materials involved. In this work a method is presented which permits the metallographic preparation of the lithium-carbon intercalation compounds used as anode materials in today's rechargeable lithium ion batteries, and which allows the details of their microstructures to be contrasted. After classic, but absolutely water free, preparation in a protective gas atmosphere, the final stage of preparation is carried out using both ion beam polishing and manual polishing on a stationary polishing disc, whereby no significant differences of the quality of the microstructural images obtained is apparent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
