Title: Motoharu Obika: Innovator in Battery Technology
Introduction
Motoharu Obika is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of battery technology, holding a total of 11 patents. His innovative work focuses on the development of advanced battery systems that enhance performance and efficiency.
Latest Patents
One of his latest patents is for a bipolar battery. This bipolar battery includes a power generation element formed by stacking multiple bipolar electrodes, with an electrode layer on both the front and rear of a collector, separated by an electrolyte layer. It features an elastic metal portion that contacts the power generation element in either point or line contact when no external force is applied, and in surface contact when external force is exerted. The design also incorporates an outer covering material that maintains an internal air pressure lower than atmospheric pressure, allowing the elastic metal portion to achieve surface contact with the power generation element due to the pressure difference.
Another notable patent is for a bipolar secondary battery and its production method. This battery consists of a battery element that includes first and second bipolar electrodes, each equipped with a collector covered by a conductive resin layer. The positive and negative electrode active material layers are formed on opposite sides of the collector, with a separator containing a second resin layer positioned between the bipolar electrodes. The positive electrode active material layer, electrolyte layer, and negative electrode active material layer together form a unit cell, which is sealed by fusing the outer peripheries of the collectors and the separator.
