Latest Patents
Shibahara's latest patents focus on innovative designs for lead-acid batteries. One patent describes a lead-acid battery where each negative plate is in contact with a non-woven fabric made from materials such as glass, pulp, and polyolefins. This fabric covers the entire surface of the plate without being integrated into it. The negative plate is housed in an envelope separator made of a microporous synthetic resin sheet, which is laminated with a positive plate. The non-woven fabric is produced through a papermaking process that disperses glass fibers, pulp, and silica powder in water.
Another patent details improvements in valve-regulated lead-acid batteries. This design allows for intermittent charging and high-rate discharging while in a partial state of charge (PSOC). The battery features a positive electrode plate with a specific surface area of 5.5 m/g or more. Additionally, the negative electrode plate is enhanced for charge acceptance and longevity by incorporating a carbonaceous electroconductive material and a formaldehyde condensate of bisphenols aminobenzene sulfonic acid. The electrolyte's specific gravity is maintained between 1.30 and 1.35.
