Abstract
Methods for preparing a solid electrolyte membrane are described. More particularly, a small amount of binder may be fiberized through a dry calendering process to prepare a solid electrolyte membrane. Since the fiberized binder is included in an entangled state within the solid electrolyte membrane, it shows excellent characteristics in both ionic conductivity and strength.
Claims20
A method for preparing a solid electrolyte membrane film, comprising:
- (S1) mixing a plurality of solid electrolyte particles and a binder to form a mixture, wherein the binder is fiberized by the mixing;
- and
- (S2) applying the mixture obtained in (S1) to a calendering process to form a solid electrolyte membrane film.
