Latest Patents

One of her latest patents is for a flat-type battery. This invention includes a power-generating element accommodated in an inner space formed by sealing the outer peripheral edges of package members. The design features a collector connected to an electrode plate of the power-generating element and an electrode tab taken out from the outer peripheral edges of the package members. The electrode tab has a conducting portion overlapping and joined to the collector, along with a stress-relieving portion made of a material with higher elasticity than that of the conducting portion. This innovative design helps prevent the occurrence of wrinkles in the collector or electrode tab and separations in weld joints due to differences in expansion and contraction rates.

Another notable patent is for a process for producing fine particles of bismuth titanate. This process aims to provide fine particles with excellent dielectric characteristics, high crystallinity, and a small particle diameter. The method involves obtaining a melt comprising specific percentages of BiO, TiO, and BO, quickly quenching this melt to obtain an amorphous material, crystallizing bismuth titanate crystals from the amorphous material, and separating the crystals from the crystallized material.
