Latest Patents
Fukushima's latest patent involves an electrode for an electric double layer capacitor. This invention specifies that the peak value of particle size distribution of graphite particles added to a conductive adhesive should be in a range of 2.6 to 3.2 μm. Additionally, it requires the formation of not less than 100,000 dimples on the surface of the collector sheet per 1 cm, with a largest outer diameter ranging from 4 to 10 μm and a depth between 4 to 15 μm. The occupied area of these dimples should not exceed 50% of the entire surface area of the collector sheet. Furthermore, by determining the saponification value of polyvinyl alcohol used as a binder component of the conductive adhesive within a range of 90.0 to 98.5, the adhesiveness of the collector sheet and the electrode forming sheet is significantly improved. The substitution of hydrogen atoms in polyvinyl alcohol with silicon atoms further enhances this adhesiveness.
