Abstract
Official abstract text for this publication.
A non-aqueous electrolyte secondary battery includes: a positive electrode plate; a negative electrode plate; and a separator disposed between the positive electrode plate and the negative electrode plate. The separator includes a porous resin layer. The porous resin layer is made of polyolefin having a melting point of 80° C. or more and 135° C. or less. At least one of the positive electrode plate and the negative electrode plate has a surface facing the porous resin layer. The surface forms a contact angle of 30° or more with a molten droplet of the polyolefin.
First claim
Opening claim text (preview).
What is claimed is: 1 . A non-aqueous electrolyte secondary battery comprising: a positive electrode plate; a negative electrode plate; and a separator disposed between the positive electrode plate and the negative electrode plate, the separator including a porous resin layer, the porous resin layer being made of polyolefin having a melting point of 80° C. or more and 135° C. or less, at least one of the positive electrode plate and the negative electrode plate having a surface that faces the porous resin layer, and the surface forming a contact angle of 30° or more with a molten droplet of the polyolefin. 2 . The non-aqueous electrolyte secondary battery according to claim 1 , wherein the contact angle is 30° or more and 60° or less. 3 . The non-aqueous electrolyte secondary battery according to claim 2 , wherein the contact angle is 45° or more and 60° or less.
