Latest Patents
One of Kuwamura's latest patents focuses on an improved non-aqueous electrolyte cell. This invention comprises an anode, a cathode, and a separator that is spirally wound, allowing the anode to be positioned on the outer side of the cathode to form an electrode assembly. The design includes an electrically insulating material wrapped around the outermost end of the cathode. Additionally, the anode features a section with an anode current collector located near the outermost end, which is positioned beyond the wrapped outermost end of the cathode. A reaction suppressing layer is strategically placed between the cathode section and the anode, ensuring that only the outer side of the cathode reacts with the anode. This innovative design minimizes capacity loss during the final discharge stage by disconnecting any remaining non-reacted anode components from the current collector.
