Title: Innovator Spotlight: Tomoyuki Aita
Introduction
Tomoyuki Aita, a notable inventor based in Iwaki, Japan, has made significant contributions to the field of electrochemical devices. With a total of two patents to his name, Aita has focused on developing advanced materials and processes that enhance the efficiency of batteries and electric double-layer capacitors.
Latest Patents
Aita’s latest inventions include two innovative patents that address the challenges faced by electric double-layer capacitors. The first patent describes a carbonaceous material specifically designed for electric double-layer capacitors. This material boasts a large capacitor per volume, low resistivity, and substantial bulk density. It features a specific surface area ranging from 800 to 2000 m²/g, as measured by the nitrogen adsorption BET method, and an average layer-plane spacing of at most 0.36 nm determined by the X-ray diffraction method. The material is produced by carbonizing and activating a carbon precursor of pitch origin in an oxidizing atmosphere.
The second patent is focused on a binder solution formulated for electrode applications in non-aqueous-type electrochemical devices, including batteries and electric double-layer capacitors. This solution is created through the dissolution of a vinylidene fluoride polymer with an inherent viscosity surpassing conventional levels, in an organic solvent. The electrode-forming composition is prepared by dispersing powdered electrode material in the binder solution and applying it to an electroconductive substrate, ensuring the polymer does not gel. This creates a composite electrode layer that maintains lesser amounts of vinylidene fluoride polymer while offering strong resistance to non-aqueous electrolytic solutions.
