Latest Patents

One of Yonezu's latest innovations is the monoblock sealed lead-acid storage battery. This invention features a sealed lead-acid battery formed by joining two halves of a battery container. Before joining, the separate halves have grids placed in adjacent recesses, separated by partition walls integral with the wall of the container half. Pairs of adjacent grids are electrically connected through the partition wall, and the recesses are alternately filled with positive and negative active materials. The halves are then joined with a porous separator in each cell of the combined halves, effectively separating the positive and negative active materials.

Another notable patent is the specific gravity detecting device for lead-acid batteries. This apparatus includes two electrodes that are immersed in an electrolyte to provide a potential difference indicative of the specific gravity of the electrolyte. One electrode is a lead electrode composed of a collector made of lead and a lead alloy, while the other is a lead dioxide electrode. The two electrodes can be charged normally or as required, allowing for accurate determination of the potential difference in the open-circuit state.
