Title: Innovations of Shoji Karasawa
Introduction
Shoji Karasawa is a notable inventor based in Kosai, Japan. He has made significant contributions to the field of battery technology, holding a total of 6 patents. His work focuses on enhancing the efficiency and performance of prismatic sealed batteries.
Latest Patents
One of his latest patents is the prismatic sealed battery. This invention features a prismatic battery case that includes multiple prismatic containers arranged in a row. These containers are coupled via partitions, electrode plate assemblies, and collectors that connect to lead portions on both sides of the electrode plate assemblies. An opening is formed in at least one side wall of the prismatic battery case, allowing for a conductive connection member to be connected to the collectors on both sides of the partition. This design reduces internal resistance and enhances power output by fully utilizing the electrode plate assembly.
Another significant patent is the battery manufacturing method and apparatus. In this process, positive and negative electrode plates are layered alternately with separators in between to form electrode plate groups. These groups are transferred through a series of preliminary chambers with varying vacuum levels, ultimately reaching a processing chamber where collector plates are welded to the electrode plate groups using an electronic beam. This innovative method streamlines the manufacturing process and improves the quality of the batteries produced.
