Abstract
A lithium ion conducting membrane and methods of making the same. The membrane includes a polymeric matrix and a plurality of ion-conducting particles disposed within the polymeric matrix. An inorganic coating deposited in the polymeric matrix.
Claims7
A method of making a hybrid inorganic/organic membrane comprising:
- forming an organic polymer framework having a plurality of pores;
- binding lithium ions to a plurality of inorganic particles, by electrostatic forces selected from the group consisting of Strong Electrostatic Attraction technique and Incipient Wetness Impregnation technique, forming a plurality of ion-conducting particles;
- and
- integrating the plurality of ion conducting particles into the organic polymer framework, the plurality of ion-conducting particles forming an array of columns of inorganic lithium ion conductor in the organic polymer framework;
- wherein the hybrid inorganic/organic membrane comprises the plurality of ion conducting particles integrated within the plurality of pores of the organic polymer framework.
