Document Type and Number:
WIPO Patent Application WO/2022/145107
Kind Code:
A1
Abstract:
Provided are a non-aqueous electrolyte secondary battery having excellent charging load characteristics, a method for manufacturing the non-aqueous electrolyte secondary battery, a negative electrode that can constitute the non-aqueous electrolyte secondary battery, a method for manufacturing the negative electrode, and a method for inspecting the negative electrode for manufacturing the non-aqueous electrolyte secondary battery. The present invention relates to goals 7 and 12 of the SDGs. A negative electrode for non-aqueous electrolyte secondary batteries according to the present invention has, on one or both surfaces of a collector, a negative electrode mixture layer containing a negative electrode active material, wherein (1) Rs/(ρv×d) is within a prescribed range according to the thickness of the negative electrode mixture layer, or (2) Rs≤1.67d+b is satisfied, where Rs (Ωcm2) is the interface resistance between the negative electrode mixture layer and the collector, ρv(Ωcm) is the volume resistivity of the negative electrode mixture layer, and d (cm) is the thickness of the negative electrode mixture layer. A non-aqueous electrolyte secondary battery according to the present invention comprises a positive electrode, a negative electrode, and a non-aqueous electrolyte and separator interposed between the positive electrode and the negative electrode, wherein the negative electrode is the negative electrode for non-aqueous electrolyte secondary batteries according to the present invention.
