Abstract

High rate and high crush-strength adsorbent particles and collections of such particles, and particularly LiLSX particles, are provided. A binder is employed in the form of a colloidal solution during the method of manufacture. Suitable binders include various silica binders. The particles are made using the steps of mixing, agglomeration, calcination and in the case of certain adsorbents such as LiX and LiLSX, ion exchange and activation. When the adsorption rate is expressed in the form SCRR/ε(mmol mm/g s), desirable collections of adsorbent particles can have values of at least 4.0 for the highly-exchanged Li (at least 90% Li exchanged) form of the collection of particles and can further be characterized by particles having average crush strengths of at least 0.9 lbf for particles having an average diameter of at least about 1.0 mm.
