Powder Process for Improvement of Performance and Quality of Battery

Abstract

Battery is one of the key technology for environmental-conscious vehicles. A high performance battery can be obtained by keeping effective electrochemical reaction under control of suitable conditions. Various conditions must be cleared to satisfy this requirement. One of condition is to control electrode materials. Investigations of new chemicals are major way as chemical method, on the other hand, the utilization of fine solid, i.e. powder, is applying as physical method. Powders can promote chemical reactions due to its huge specific surface area. Shorten transportation time of ion in solid, because the distance between inside of solid and the surface is short, can give better performance for battery.

Therefore powder technologies are applying to manufacture and R&D of major materials for secondary batteries and fuel cells. I'll introduce the role of powder technology for manufacturing/R&D of synthesis process of active materials, post processing of active materials, and evaluation of electrode, respectively.
