Digital Manufacturing of Lithium-ion Batteries using Inkjet Printing

11:00-11:30 Pre-Registration required

【Abstract】

As electronic vehicles and state-of-the-art electronic devices become more widespread, more lithium-ion batteries (LIBs) with the required functionality will be needed. In order to meet the demand of LIB, it is strongly desired to change the traditional manufacturing process to a new efficient process that is low cost, high productivity and environmentally friendly.
This presentation presents an approach to transforming the LIB manufacturing process from analog to digital using Ricoh’s industrial inkjet (IJ) printing technology. We would also like to share some possibilities regarding the application of the IJ process to next generation LIB. Digital manufacturing based on IJ printing has advantages such as LIB safety, highly efficient material use and productivity improvement, and we hope to bring innovation to the production of LIB.

Development of Clay-type Lithium-Ion Battery and Their Advantages

11:30-12:00 Pre-Registration required

【Profile】

Graduated from the Faculty of Engineering, Yamaguchi University. He has been in charge of research and development of lithium secondary batteries for about 10 years at Yuasa Battery Corporation. He developed a 10Ah battery using a metallic lithium negative electrode and a polymer solid electrolyte type lithium ion battery. Since moving to Kyocera, he has been mainly engaged in the development of oxide-based all-solid-state lithium-ion batteries. In 2013, we started joint development of clay-type batteries with a US battery venture, and in October 2019, we launched Enerezza, a power storage system equipped with a clay-type lithium-ion battery.

【Abstract】

As the need for measures to prevent global warming is being called for, expectations for lithium-ion batteries (LIB) are increasing in order to expand clean energy. In particular, there is a demand for secondary batteries that are low in cost, have a long life, and have excellent environmental performance. As one battery candidate that meets these requirements, we would like to introduce the clay-type LIB jointly developed by 24M and Kyocera. At the same time, we will introduce the electricity storage system [Enerezza] equipped with clay-type LIB, and also report on the environmental performance of clay-type batteries and future development.

Development of oxide-based small all-solid-state batteries suitable for IoT applications

12:00-12:30 Pre-Registration required

【Profile】

I finished graduate school of Tokyo University of Science in March 1982. The research theme was oxide-based solid electrolytes. At Sony, I was in charge of the design of silver oxide and lithium batteries, as well as the development of sulfide-based all-solid-state batteries, 1.5 V-class lithium batteries, and lithium-based secondary batteries. I had participated in the world's first lithium-ion battery commercialization project since its inception. In September 2017, I transferred to Murata Manufacturing Co., Ltd., which took over Sony's battery business, and have been involved in research and development of innovative batteries and all-solid-state batteries.

【Abstract】

As next-generation storage device, the practical application of all-solid-state battery (ASSB) is approaching. Sulfide ASSBs with excellent rapid charging characteristics are expected to be applied to EVs, and oxide ASSBs with high chemical stability are expected to be applied to IoT and wearable devices. In this lecture, the general overview of ASSBs and specific examples of oxide-based ASSBs will be introduced.
