Document Type and Number:
WIPO Patent Application WO/2020/091026
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a non-aqueous electrolyte secondary battery exhibiting excellent discharge capacity recovery characteristics after charge/discharge cycles. A non-aqueous electrolyte secondary battery according to the present invention comprises: a porous layer containing an inorganic filler and a resin; a positive electrode plate which can endure at least 130 bending events until an electrode active material layer is peeled off; and a negative electrode plate which can endure at least 1650 bending events, wherein the porous layer has a scratch test value represented by a specific equation in the range of 0.10-0.42.
