Latest Patents
One of Hanzawa's latest patents focuses on an electrodeposited copper foil. The invention aims to provide a copper foil with excellent adhesion to an etching resist layer, eliminating the need for physical polishing in the pre-treatment process. This is achieved by employing a titanium material with a specific grain size as the copper deposition surface and adding glue or gelatin to the copper sulfate solution. The resulting copper foil, characterized by a twin-crystal structure, is particularly useful for producing copper-clad laminates.
Another significant patent involves a cathodic active material for dry cells. This material consists of a mixture of graphite particles and electrolytic manganese dioxide particles, which have a needle-like crystal structure. The preparation method includes mixing carbon powder with manganese dioxide powder and pulverizing the mixture. This innovative cathodic active material enhances the performance of alkaline manganese dioxide cells, particularly in high load-discharge scenarios.
