Latest Patents

Minami holds a patent for a "Nonaqueous electrolyte secondary battery including negative electrode active material layer with reasonable large tortuosity ratio." This patent describes a unique design where, in a cross-section parallel to the thickness direction of a negative electrode active material layer, the average tortuosity ratio is maintained between 1.5 to 2.5. The average tortuosity ratio is calculated using the formula 'R=B/A', where “R” represents the average tortuosity ratio, “B” is the average value of lengths of shortest routes from a contact point between a negative electrode substrate and a negative electrode active material particle to the surface of the negative electrode active material layer, and “A” is the average value of the thicknesses of the negative electrode active material layer. This innovation is crucial for improving the efficiency of battery performance.
