Abstract: A method of preparing a recycled polymer may include: preparing a mixed solvent including a first solvent and a second solvent and supplying the mixed solvent to each of a dissolution tank and a precipitation tank, supplying a composite resin to the dissolution tank and dissolving the resin to obtain a dissolved mixture, filtering the dissolved mixture to obtain a polymer solution, and supplying the polymer solution to the precipitation tank and performing recrystallization to obtain a precipitated mixture including a recycled polymer.

Abstract: The present disclosure relates to a separator for an electrochemical device and an electrode assembly comprising the same. More particularly, the present disclosure relates to a separator with improved interfacial adhesion with electrode and an electrode assembly comprising the same. The adhesion layer according to the present disclosure includes a first layer contacting a surface of the separator and a second layer formed on a surface of the first layer and contacting with an electrode, the first layer includes a polymer resin with a fluorine-containing monomer, and the second layer includes a polymer resin having a lower dissolution rate in an electrolyte solution for an electrochemical device than the polymer resin included in the first layer.
