Abstract
Official abstract text for this publication.
An adhesive layer disposed between a separator for a secondary battery and an electrode for a secondary battery, wherein the adhesive layer is obtained by bonding under pressure a layer containing a resin having a structural unit derived from an α-olefin having 2 to 4 carbon atoms, and an occupancy area of the resin in the adhesive layer is 10 to 80%.
First claim
Opening claim text (preview).
The invention claimed is: 1. An adhesive layer disposed between a separator for a secondary battery and an electrode for a secondary battery, wherein the adhesive layer is obtained by bonding under pressure a layer containing a resin having a structural unit derived from an α-olefin having 2 to 4 carbon atoms, and an occupancy area of the resin in the adhesive layer is 10 to 80%, the adhesive layer further comprising a nonionic surfactant, the nonionic surfactant being a polyvinyl alcohol optionally having a sulfo group, a polyoxyethylene alkylphenyl ether, a polyoxyethylene alkyl ether, a polyoxyethylene fatty acid ester, a polyoxyethylene sorbitan fatty acid ester, and/or a polyoxyethylene-polyoxypropylene block copolymer, and the adhesive layer contains the resin having a structural unit derived from an α-olefin having 2 to 4 carbon atoms in an amount of 0.05 g/m 2 or more and less than 0.11 g/m 2 . 2. The adhesive layer according to claim 1 , wherein the resin having a structural unit derived from an α-olefin having 2 to 4 carbon atoms has a lowest film-forming temperature of 40 to 150° C.
