Latest Patents
One of Maeda's latest patents is a non-woven fabric for the separator of alkali cells and the method for its production. This invention provides a non-woven fabric for an alkaline battery separator that comprises semi-aromatic polyamide fibers. These fibers include a dicarboxylic acid component, where 60 mol % or more is an aromatic carboxylic acid component, and a diamine component, where 60 mol % or more is an aliphatic alkylene diamine with 6 to 12 carbon atoms. The separator non-woven fabric exhibits superior alkaline resistance, with a weight loss rate of 5% or less after 20 days in an alkaline resistance test at 90°C in aqueous KOH solution. This innovation enables rapid charging and large-current discharging while allowing for reduced thickness, making it ideal for alkaline battery separators.
Another notable patent by Maeda is the heat-accumulating microcapsule dispersion. This invention includes microcapsules that function as heat-accumulating materials, which are accommodated within a microcapsule. The dispersion also contains a heat transfer fluid medium with a number of microcapsules stably dispersed within it, along with thermal boundary layer stirring particles. These stirring particles have a volume average particle diameter that enhances the thermal boundary layer's movement inside the heat exchanging passage.
