1. A method of preparing functional lithium exchanged zeolite particles for an electrochemical cell, the method comprising:
(a) combining a solution comprising (NH4)3PO4 with lithium ion-exchanged zeolite particles to form a first mixture; and
(b) adding a polymeric binder and a lithium salt to the first mixture to form a first slurry comprising the functional lithium ion-exchanged zeolite particles comprising Li3PO4.
