Guide to Lithium-ion Battery Solutions
Demand for lithium-ion Battery is expected to expand further in the
future, driven by demand for electric vehicles, which are supported
by policies in various countries around the world, and demand for PC,
smartphone, and tablet device, which are driven by digital transforma-
tion (DX). In addition, companies and research institutes around the
world are actively engaged in research and development to commer-
cialize all-solid-state batteries as next-generation battery. This guide
book provides total solutions for each evaluation or material of
Lithium-ion Battery development.

Multilateral Evaluation of Positive and Analysis of MEA
Negative Electrodes in Lithium-ion Batteries (Membrane Electrode Assembly)
In recent years, the applications of lithium-ion battery have expanded Electrochemical devices in which electrode catalyst layers are bonded on
dramatically, and research on increasing capacity, extending life, reducing a solid polymer electrolyte membrane, which is a hydrogen ion conductor,
cost, and improving safety has been actively conducted. The components are called membrane electrode assemblies (MEA). Among their uses are
