Latest Patents
Ishihara's latest patents include a groundbreaking design for solid state batteries. This innovation features a stack of cells, each comprising a positive electrode, a negative electrode, and a solid electrolyte positioned between them. A current collector is strategically placed between the negative electrode of the first cell and the positive electrode of the second cell, which is adjacent to the first. The solid state battery incorporates an ionic conductor with two configurations: a normal configuration where the ionic conductor is not in contact with the current collector, and a short-circuit configuration where it is in contact. This design ensures that the ionic conductivity is lower than the electronic conductivity of the current collector.
Another significant patent by Ishihara is a system and method for charge protection of a lithium-ion battery. This method involves monitoring and storing the temperature of a solid-state battery with a sulfur-based positive electrode. When the temperature exceeds a predetermined threshold, the method monitors the temperature for indications of sulfur sublimation and terminates the flow of charge current upon detection. This innovation aims to enhance the safety and longevity of lithium-ion batteries.
