Title: The Innovative Contributions of Michibata Sachio in Battery Technology
Introduction: Michibata Sachio is a prominent inventor based in Osaka, Japan. With an impressive portfolio of two patents, he has made significant strides in the field of battery technology. His innovations focus on the development of advanced battery cans, leveraging intricate techniques in material science and engineering.
Latest Patents: Michibata's latest patents include a revolutionary design for a battery can and a detailed method for manufacturing it. The core of his invention involves a steel plate with a plated layer on both surfaces, which is designed to be formed into a cylindrical battery can that is open at one end. The process utilizes drawing and ironing techniques and requires a steel plate with a Lankford value (r) exceeding 1.2. This value measures the width deformation degree relative to thickness in various directions. Additionally, the in-plane anisotropy Ar, which reflects variations among Lankford values, is meticulously controlled to be less than ±0.15. This precision ensures that the elongation coefficient remains consistent across lengthwise, widthwise, and oblique directions, ultimately preventing earring during manufacturing processes. In achieving this, Michibata uses a very low carbon steel plate that is cold-rolled to 80-90%, with an annealing process applied to allow the plated layer to attain a granular structure.
Career Highlights: Michibata Sachio's foundational career has been built upon his role at Katayama Special Industries, Ltd., where he has honed his expertise in the innovative engineering of battery components. His contributions have not only advanced the efficiency of battery production but also enhanced the material properties necessary for optimal performance in various applications.
Collaborations: Throughout his career, Michibata has collaborated with esteemed colleagues such as Sugikawa Hirofumi and Hayashi Keiichi. Together, they have progressed the boundaries of what is possible in battery technology, showcasing the importance of teamwork and collective innovation in driving advancements.
