Abstract: An electrochemical cell of a secondary lithium ion battery includes lithium ion-exchanged zeolite particles or “lithiated zeolite particles” positioned along at least a portion of a lithium ion transport path through the electrochemical cell. The lithiated zeolite particles may be positioned within the lithium ion transport path through the electrochemical cell, for example, by being distributed throughout an electrolyte disposed between confronting anterior surfaces of a negative electrode and a positive electrode. Additionally or alternatively, the lithiated zeolite particles may be positioned within the lithium ion transport path through the electrochemical cell by being distributed throughout or deposited as a coating layer on the negative electrode, the positive electrode, and/or a porous separator sandwiched between the confronting anterior surfaces of the negative and positive electrodes.

Abstract: A composite porous separator for an electrochemical cell of a secondary lithium ion battery includes particles of a lithium ion-exchanged zeolite material. The composite porous separator may be manufactured by preparing a slurry comprising a polymeric binder material and the particles of the lithium ion-exchanged zeolite material, and then depositing the slurry on one or more sides of a porous substrate. Thereafter, the slurry may be dried to form a solid microporous active layer on the one or more sides of the substrate.

Abstract: Methods of preparing a sinter-resistant catalyst include forming a dual coating system. A surface of a particulate catalyst support contacts a first liquid precursor including a metal salt with an element selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), titanium (Ti), silicon (Si), magnesium (Mg), zinc (Zn), and combinations thereof. The first liquid precursor precipitates or is adsorbed as an ion on a portion of the surface forming a first coating including a porous metal oxide on the surface. The surface may be contacted with a second liquid precursor including a metal oxide sol including a metal selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), iron (Fe), titanium (Ti), silicon (Si), and combinations thereof. A second coating is formed from the second liquid precursor on a portion of the surface to create the sinter-resistant catalyst system.

Abstract: Catalysts that are resistant to high-temperature sintering and methods for preparing such catalysts that are resistant to sintering at high temperatures are provided. The catalyst may be prepared by contacting a solution comprising an ionic species with one or more charged surface regions of a catalyst support. A surface of the catalyst support further includes one or more catalyst particles disposed adjacent to the one or more charged surface regions. The ionic species has a first charge opposite to a second charge of the one or more charged surface regions. Next, the ionic species is associated with the one or more charged surface regions to form a layer on the one or more select surface regions. The layer is calcined to generate a coating comprising metal oxide on the one or more select surface regions, where the coating is formed adjacent to the one or more catalyst particles.
