Title: Innovative Contributions of Hayashi Keiichi
Introduction:
Hayashi Keiichi, an accomplished inventor based in Osaka, Japan, has made significant strides in the field of battery can technology. With a strong background in materials engineering, he holds two patents that showcase his innovative approach to manufacturing processes and materials.
Latest Patents:
Hayashi's latest patents focus on the development of a battery can and a corresponding method for manufacturing. His inventions detail a steel plate featuring a plated layer on both surfaces, which is processed into a cylindrical battery can that remains open at one end through the drawing and ironing method. The plated steel plate is characterized by a Lankford value (r) exceeding 1.2, ensuring desirable deformation properties in various directions. Furthermore, he meticulously specifies that the in-plane anisotropy (Δr) should be maintained below ±0.15, thereby preventing the generation of earring during the production process. To achieve consistent elongation coefficients across all directions, Hayashi employs a very low carbon steel plate, which is cold-rolled at 80-90%, and the plated layer undergoes an annealing process to develop a granular structure.
