LITHIUM ION-EXCHANGED ZEOLITE PARTICLES FOR ELECTROCHEMICAL CELLS AND METHODS OF MAKING THE SAME

Lithium ion-exchanged zeolite particles and methods of making such lithium ion-exchanged zeolite particles are provided herein. The method includes combining precursor zeolite particles with (NH)POto form a first mixture including intermediate zeolite particles including NH cations. The method further includes adding a lithium salt to the first mixture to form the lithium ion-exchanged zeolite particles, or separating the intermediate zeolite particle from the first mixture and combining the intermediate zeolite particles with the lithium salt to form the lithium ion-exchanged zeolite particles.
