Panasonic Energy Battery R&D Facility Opens in Osaka

Panasonic Energy Battery R&D Facility Opens in Osaka

Panasonic Energy Co., Ltd., a subsidiary of Panasonic Holdings Corporation, announced September 16 that its Panasonic Energy battery R&D facility, called Energy Innovation Square, has opened in Kadoma, Osaka. The new lithium-ion battery research and development site is designed to function as a global hub for battery development and production. Its capabilities cover battery cell material development, design, prototyping, and analysis. Approximately 500 employees working in cell product planning, technology development, and analysis will operate at the facility, bringing several previously distributed development activities together under one location.

Battery Development Operation Expands Across Osaka

Energy Innovation Square will operate alongside the Suminoe Production Development Facility in Osaka City, which specializes in manufacturing technology development. Together, the two locations will create a dedicated battery development operation employing approximately 800 people. Through closer coordination between technology development and manufacturing activities, Panasonic Energy Co., Ltd. aims to connect development work with mass production more seamlessly and double development efficiency by FY2031 compared with FY2024. The arrangement is intended to strengthen the transition from technical development to manufacturing across the company's battery operations.

Centralized Processes Target Shorter Development Lead Times

The new facility consolidates development and prototyping processes that were previously distributed across multiple locations. Panasonic Energy expects this consolidation to reduce development lead times associated with transportation by more than 15%. The company will also use a digital transformation platform that combines simulation data with physical-test data to shorten development periods and improve design maturity. Technologies and manufacturing processes developed through these activities are planned for deployment throughout the company's manufacturing network, including facilities in Japan and its Nevada and Kansas factories in the United States.

Energy Innovation Square Supports Diverse Battery Demand

Energy Innovation Square has six floors above ground and approximately 24,500 square meters of total floor area. The facility is intended to address increasingly diverse battery requirements, including high-energy-density and highly durable batteries for electric vehicles. It will also support development of higher-output batteries for AI data centers, extending the scope of the company's battery research beyond automotive applications. By bringing material development, cell design, prototyping, and analysis together, the site provides a centralized environment for advancing battery technologies and manufacturing processes before they are introduced across the broader production network.

Industry Impact & Outlook

Energy Innovation Square strengthens Panasonic Energy's ability to connect battery research, prototyping, testing, and manufacturing development within a more centralized operation. The combination of the new Kadoma facility with the Suminoe Production Development Facility could make coordination between development teams and manufacturing technology teams more direct, while the company's planned use of integrated simulation and physical-test data is intended to reduce development time and improve design maturity. The resulting technologies and processes are expected to have relevance across Japan and U.S. manufacturing operations, while the facility's focus on EV and AI data-center batteries reflects the company's need to address different performance requirements.
