Air Protection System for Structural Analysis of High Active Materials

Takahiro Sato, Akinari Morikawa, Yuya Suzuki and Toshiyuki Iwahori

Abstract: In order to analyze high active materials such as lithium ion battery’s electrodes, an air protection system was developed consisting of air protection specimen holders, a glove box, a focused ion beam system and an electron microscope. The effectiveness was tested using negative electrode of lithium ion battery after charged. As a result, it is possible to transport, fabricate and observe it without specimen transformation. The distribution of lithium was clearly identified.

Key words: Air protection system, Focused ion beam system, Electron microscope, Air protection holder, Lithium ion battery
