摘要： An sealing tape for a rechargeable lithium battery and a rechargeable lithium battery including the sealing tape are provided. The sealing tape for a rechargeable lithium battery includes a single-layer adhesive layer having adhesiveness on both opposite surfaces of the adhesive layer, wherein the adhesive layer includes a (meth)acrylic copolymer and a crosslinking agent, and the (meth)acrylic copolymer includes a moiety derived from a first substituted or unsubstituted C1 to C20 alkyl (meth)acrylate-based compound; a moiety derived from a second substituted or unsubstituted C3 to C20 cycloalkyl (meth)acrylate-based compound; a moiety derived from a third hydroxy group-containing compound; and a moiety derived from a fourth unsaturated morpholine-containing compound.
