Title:
POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE STORAGE ELEMENT AND NONAQUEOUS ELECTROLYTE STORAGE ELEMENT
Document Type and Number:
Japanese Patent JP2022083352
Kind Code:
A
Abstract:
To provide a positive electrode for a nonaqueous electrolyte storage element that can reduce the AC resistance of the nonaqueous electrolyte storage element even when the porosity of a positive electrode active material layer is high.SOLUTION: A cathode for nonaqueous electrolyte storage element is set to include a positive electrode active material layer containing a positive electrode active material and carbon black. The porosity of the positive electrode active material layer is 40% or more. The content of the carbon black in the positive electrode active material layer is 6 mass% or less. The maximum value of the log differential pore volume of the positive electrode active material layer at a pore size in a range of 0.04 μm or more and 0.1 μm or less is 0.24 cm2/g or more.SELECTED DRAWING: None
