Latest Patents
Ishikawa's latest patents focus on innovative designs for negative electrodes in nonaqueous electrolyte secondary batteries. One of her notable inventions is a negative electrode that features a mixture layer composed of a first layer and a second layer. The first layer is formed on the negative electrode current collector and includes a negative electrode active material along with a first binding agent. This layer incorporates a carbon material A and a silicon-containing compound, with the first binding agent being polyacrylic acid or a salt thereof. The second layer, which is formed on top of the first layer, contains a different carbon material B that has a higher tap density than carbon material A. This innovative structure enhances the performance and efficiency of the battery.
Another patent describes a negative electrode that includes a negative electrode collector and a mixed material layer. This layer consists of a first layer containing a carbon-based active material and a silicon-based active material, along with a polyacrylic acid or a salt thereof. The second layer has a greater tap density and a smaller BET specific surface area compared to the first layer. The mass distribution between the two layers is carefully designed to optimize the overall performance of the negative electrode.
