Title: Shotaro Doi: Innovator in Electrochemical Capacitors
Introduction
Shotaro Doi is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of electrochemical capacitors, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of energy storage devices.
Latest Patents
Doi's latest patents include an innovative electrochemical capacitor design. This capacitor features an electrolytic solution, a capacitor element, and a housing. The electrolytic solution is composed of cations, anions, and a solvent that is not formed of lactones, along with a lactone component. The capacitor element consists of a negative electrode, a positive electrode, and a separator. The negative electrode is designed to store cations, while the positive electrode includes a polarizable electrode layer that faces the negative electrode. The separator is strategically placed between the two electrodes, which can be layered or wound together. The entire capacitor element is impregnated with the electrolytic solution, and the housing accommodates both the capacitor element and the electrolytic solution, which contains the lactone component in a specific weight range.
Another notable patent involves an electrolyte that is highly reliable for charge and discharge under high voltage conditions. This electrolyte includes a solvent, an electrolyte salt with a perfluoro alkyl group, and an acid-inducing substance containing a fluorine atom. The design aims to prevent excessive electric potential decline of the negative electrode and protect the negative electrode's protection film from damage, thereby maintaining cycle characteristics even under high temperature or high voltage conditions.
