All-Solid-State Battery Material / Case Studies of Silicon Anode and Solid Electrolyte Analysis - Part 2 -
Release Date: 2023/01/18
Recently, all-solid-state batteries, in which Japan is leading, are attracting attention among lithium ion batteries. Compared to current lithium-ion batteries, which have the risk of smoking and igniting, all-solid-state batteries are expected to be widely used in automobiles due to their safety and high energy density.
This series of webinars are about silicon anode & solid electrolyte materials which are being studied in all-solid-state batteries.
With the cooperation of Prof. Matsuda, Toyohashi University of Technology, the webinars will provide an overview of all-solid-state batteries as well as examples of analyses performed with JEOL instruments.
This seminar will be held on the web. You can participate not only from your PC, but also from your smartphone or tablet, as long as you have access to the web. We look forward to your participation.

Program
Lecture 2
Air-isolated TEM Specimen Preparation by FIB-SEM
We will introduce the process of air-isolated TEM specimen preparation of the silicon anode material of an all-solid-state lithium ion battery using a focused ion beam (FIB) system.
Specimen preparation is possible from the flat and smooth CP cross section by directly transferring the specimen from the cross section polisher (CP) to FIB-SEM, and its high-quality TEM specimen can be prepared from the target area by using an FIB with specimen chamber manipulator, without exposing the specimen to air.
