Title: ADHESIVE FOR AFFIXING ELECTRODE ASSEMBLY AND ELECTROCHEMICAL ELEMENT
Abstract:
The present invention provides an adhesive for affixing an electrode assembly and an electrochemical element using the same. The adhesive for affixing an electrode assembly is used for an electrochemical element comprising an electrolytic solution, an electrode assembly which includes a cathode member, a separator member, and an anode member, and a pouch-shaped package housing the electrolytic solution and the electrode assembly, wherein the adhesive for affixing an electrode assembly has a swelling degree of 50% or lower with respect to the electrolytic solution. Preferably, the adhesive for affixing an electrode assembly contains a styrene block copolymer and a diene polymer, and the cathode member, the separator member and the anode member have a stacked or a jellyroll design.
