Abstract

An adhesive for batteries. The adhesive has improved wetting properties, improved adhesive strength and prevents deterioration of battery performance. Secondary batteries can be obtained having an arbitrary shape such as a thin shape with high reliability and high charge and discharge efficiency. The adhesive includes a thermoplastic resin, a solvent capable of dissolving the resin and a neutral and aprotic surfactant. The surfactant includes a polysiloxene skeleton. The adhesive is used in batteries for adhering an active material layer joined to a current collector to a separator.
