Latest Patents

One of Kyu Ota's latest patents is for a hydrophilic porous carbon electrode and its manufacturing method. This invention provides a hydrophilic porous carbon electrode that exhibits excellent hydrophilicity and high reaction activity when utilized in batteries. The electrode is designed to achieve outstanding battery characteristics. It is a sheet-form hydrophilic porous carbon electrode where carbon fibers are bonded using a resin carbide. The contact angles of water on both surfaces in the thickness direction range from 0 to 15 degrees. The manufacturing process involves forming the carbon fiber and a binder fiber into a sheet, impregnating it with a thermosetting resin, and subjecting it to heat press processing followed by carbonization at temperatures between 400 to 3000 degrees Celsius in an inert atmosphere. Additionally, the electrode undergoes a heat treatment with an oxidizing gas to enhance its hydrophilicity.

Another notable patent is for a porous electrode substrate that reduces the drop in electromotive force when used in batteries. This substrate consists of a carbon fiber sheet where carbon fibers are bound by a binder. The invention specifies that the dust generation amount per 1 square meter of the porous electrode substrate is limited to 120,000 particles or less for dust particles of 0.3 micrometers or more in size.
