Prof. Makio Naito
Makio Naito is a professor at the Joining and Welding Research Institute (JWRI), Osaka University in Japan. He served as the President of The Society of Powder Technology, Japan from 2015 to 2019. His publications cover a wide range of studies in the fields of advanced materials and novel powder processing and characterization. He has received several prestigious awards including the Richard M. Fulrath Award from the American Ceramic Society (ACerS) in 2002 and the KONA Award in 2019. He has been a Fellow of the ACerS since 2010, and serves on the ACerS Board of Directors from 2020.
Particle microstructure control and its assembly structure control are key issues for achieving high quality advanced materials. In this talk, the effect of their controls on the performance of battery materials will be explained to make clear the importance of powder processing technology. As a typical example of individual particle microstructure control, processing technology of composite particles will be introduced, and its applications for lithium-ion battery will be explained.

Research & Development
Mr. Makoto Yoshimori
Makoto Yoshimori joined Powrex in 2016 and since then, he has been working for about 6 years on the development of the processing of powder and granular materials and new working processes in the battery, chemical, pharmaceutical, and food industries. In particular, he has been engaged in particle design and equipment and application development work for processes such as particle coating, granulation, and mixing of battery materials.
Solid-state lithium batteries are lithium-ion batteries with a solid electrolyte, and have been attracting attention as next-generation batteries in recent years. In solid-state lithium batteries, the electrical resistance at the interface between the positive-electrode material and the solid electrolyte is known to cause a decrease in battery performance, and to solve this problem, a nanoscale buffer film coating is used on the surface of positive-electrode material particles. This presentation introduces a tumbling fluidized bed system, Multiplex (MP), which is widely used for coating positive-electrode particles and has benefits such as high uniformity of coating film and high denseness of film. The results of elemental technology study and examples of coatings other than buffer film are also presented. In addition, in light of the growing social demand for mass production, a case study of MP’s coating process in which the coating time was reduced to 1/10 is also introduced.
