Latest Patents

Miyachi's latest patents include innovative technologies such as a solid electrolyte membrane and a method and apparatus for producing the same. His work involves casting a dope containing a solid electrolyte and an organic solvent onto a web to form a casting membrane. A first blower unit applies dry air to the casting membrane, leading to the formation of a skin layer at the exposed surface. The casting membrane is then treated with a first liquid to reduce the remaining solvent amount before being peeled from the web. The membrane undergoes further drying in a tenter drier while being stretched, followed by contact with a second liquid in a drying chamber.

Another notable patent involves a solid electrolyte multilayer membrane, where first, second, and third dopes containing a solid electrolyte and an organic solvent are cast from a die onto a moving belt. A three-layer casting membrane is peeled off and dried, with subsequent treatment to remove the organic solvent. This innovative approach enhances the efficiency of the membrane production process.
