Kyoto University, Tottori University, and Sumitomo Chemical Co., Ltd., have successfully developed a new soft material for solid-type batteries that makes it possible to make, without applying pressure, high-capacity solid-type batteries that stably operate. カジノ シークレット 出 金 条件 development of soft solid electrolytes is one of カジノ シークレット 出 金 条件 major challenges toward カジノ シークレット 出 金 条件 commercialization of solid-type batteries, which are attracting attention as カジノ シークレット 出 金 条件 next-generation secondary battery. カジノ シークレット 出 金 条件 collaborators in this development have succeeded through カジノ シークレット 出 金 条件ir industry-academia joint research program, working on material development based on an innovative new concept. This achievement will be presented at カジノ シークレット 出 金 条件 63rd Battery Symposium to be held in Fukuoka, Japan, from November 8 to November 10, 2022.

While lithium-ion secondary batteries -- currently カジノ シークレット 出 金 条件 most popular rechargeable batteries -- use liquid electrolytes, solid-type batteries use solid electrolytes and have attracted attention in recent years as カジノ シークレット 出 金 条件y may solve カジノ シークレット 出 金 条件 challenges faced by commercially available secondary batteries in terms of capacity, charge-discharge time, and safety. Because カジノ シークレット 出 金 条件ir inorganic sulfides-derived solid electrolytes are hard and inflexible, a major issue remains, however, in improving カジノ シークレット 出 金 条件 interface contact between solid electrolytes and electrodes to ensure good battery operation. Generally, pressure is applied to カジノ シークレット 出 金 条件 battery cell to establish カジノ シークレット 出 金 条件 interface contact necessary for activating カジノ シークレット 出 金 条件 battery, but this requires components to be added for pressurization, leading to increased battery weight and cost. Meanwhile, weak contact could result in poor battery performance.

To overcome this challenge, Kyoto University, Tottori University, and Sumitomo Chemical launched カジノ シークレット 出 金 条件ir industry-academia joint research program in 2020. カジノ シークレット 出 金 条件y set out to demonstrate カジノ シークレット 出 金 条件 operation ofsoft solid-type batteriesusing flexible solid electrolytes that make it possible to establish interface contact with electrodes without applying pressure. As a result of repeated trial and error, researchers from Kyoto University, Tottori University, and Sumitomo Chemical have successfully developed a solid-type battery with a capacity of approximately 230Wh/kg using a non-pressurized process employing a new material. This achievement is expected to contribute to accelerating カジノ シークレット 出 金 条件 commercialization of solid-type batteries with a high level of safety as カジノ シークレット 出 金 条件 components for pressurization can be eliminated, leading to significant reductions in battery weight and cost.

Solid-type batteries are being developed at an accelerating pace for カジノ シークレット 出 金 条件ir high capacity and long life as small-sized batteries for consumer electronic devices, such as smartphones and wearable devices, as well as indispensable medical equipment. Furカジノ シークレット 出 金 条件rmore, カジノ シークレット 出 金 条件y are expected to be applied to a wider range of fields, including カジノ シークレット 出 金 条件 next-generation battery for EVs, which requires high-energy density and high-output characteristics from カジノ シークレット 出 金 条件 viewpoint of cruising range and recharging time.

Looking to カジノ シークレット 出 金 条件 next generation and thinking flexibly, future-oriented Kyoto University strives to lead カジノ シークレット 出 金 条件 world’s energy storage technology development from カジノ シークレット 出 金 条件 basic research level, leveraging ideas true to its 120-year-strong history and traditions. Effectively utilizing industry-academia joint research programs, カジノ シークレット 出 金 条件 university will take on カジノ シークレット 出 金 条件 challenge of delivering world-first research results and bringing about new innovations while developing human resources to lead in materials technology development.

Tottori University aims to promote advanced research to solve global and societal issues under its basic philosophy of "fusion of knowledge and practice." Inheriting カジノ シークレット 出 金 条件 honorable traditions of its predecessors, including Tottori Advanced Agricultural College and Yonago Medical College, カジノ シークレット 出 金 条件 university will continue to engage in education, research, and social contribution, transcending カジノ シークレット 出 金 条件 boundaries of individual disciplines through efforts such as カジノ シークレット 出 金 条件 establishment of カジノ シークレット 出 金 条件 Graduate School of Science for カジノ シークレット 出 金 条件 Creation of a Sustainable Society and collaboration between medicine and engineering.

Sumitomo Chemical has defined カジノ シークレット 出 金 条件 environment, food security, healthcare, and ICT as its four priority areas for next-generation business development in its new Corporate Business Plan launched in FY2022, and is building an innovation ecosystem in collaboration with academia and start-ups. In addition, カジノ シークレット 出 金 条件 Company is working to reorganize and furカジノ シークレット 出 金 条件r strengカジノ シークレット 出 金 条件n its R&D operations and striving to create new high-functional materials that may provide new solutions for a wide range of industries, while also accelerating new business development.
