Abstract: A cell for use in an electrochemical cell, e.g., a lithium-ion secondary battery, that includes a positive electrode with an active material acting as a cathode and a current collector; a negative electrode with an active material acting as an anode and a current collector; a non-aqueous electrolyte; and a separator placed between the electrodes. At least one of the cathode and anode includes an inorganic additive in the form of a zeolite having a Si:Al ratio ranging from 2-50 that absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride that become present in the cell. Multiple cells may be combined in a housing to form a lithium-ion secondary battery. The inorganic additive may be incorporated as part of the positive electrode, the negative electrode, or a combination thereof.

Abstract: A method of continuously forming AEI-type zeolites in a tubular reactor via a hydrothermal synthesis. A gel composition formed upon using this method includes one or more sources of silica, alumina, organic structure directing agents (OSDA), alkali metal ions; water; and optionally zeolite seeds. This gel composition is defined by the molar ratios of SiO2/AI2O3 15:1 to 100:1; M2O/SiO2 0.15:1 to 0.30:1; ROH/SiO2 0.05:1 to 0.2:1; and H2O/SiO2 5:1 to 20:1; wherein M is the alkali metal ion and R is an organic moiety derived from the OSDA. This gel composition, after reacting at a temperature between 180° C. to about 220° C. for less than 2 hours forms the crystalline AEI-type zeolite having a silica to alumina ratio (SiO2/AI2O3) that is greater than 14:1.

Abstract: A method of forming an AFX zeolite in a hydrothermal synthesis that exhibits a silica to alumina (SiO2AI2O3) molar ratio (SAR) that is between 8:1 and 26:1; has a morphology that includes one or more of cubic, spheroidal, or rhombic particles with a crystal size that is in the range of about 0.1 micrometer (μm) to 10 μm. This AFX zeolite also exhibits a Brönsted acidity that is in the range of 1.2 mmol/g to 3.6 mmol/g as measured by ammonia temperature programmed desorption. A catalyst formed by substituting a metal into the framework of the zeolite exhibits about a 100% conversion of NO emissions over the temperature range of 300° C. to 650° C.

Abstract: A negative electrode for use in an electrochemical cell, such as a lithium-ion secondary battery that includes a positive electrode with an active material that acts as a cathode and a current collector; a negative electrode with an active material that acts as an anode and a current collector; a non-aqueous electrolyte; and a separator placed between the positive and negative electrodes. The negative electrode, includes an inorganic additive dispersed therein or applied as a coating thereon, the inorganic additive being in the form of one or more zeolites having a Si:Al ratio ranging from 1-50 that absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride that become present in the cell. One or more of the cells may be combined in a housing to form a lithium-ion secondary battery.

Abstract: A crystalline, core-shell hybrid Chabazite (CHA) material for use as a catalyst has a core with a silicon to aluminum ratio (SAR) that is less than 25 and a shell that at least partially encapsulates the core, the shell having an SAR of about 25 or greater. The crystalline, core-shell hybrid Chabazite is prepared by forming a first chabazite (CHA) material having a silicon to aluminum ratio (SAR) that is less than 25, placing the first CHA material into an aqueous reaction mixture comprising one or more precursors capable of forming a second chabazite (CHA) material having an SAR that is 25 or greater, growing the second CHA material on the surface of the first CHA material, and collecting the core-shell hybrid CHA material.

Abstract: The present disclosure generally provides novel STT-type zeolite materials called PIDC-120501, PIDC-120502, and PIDC-120805/120806 or PIDC-type zeolites and a method of making these zeolites. The present disclosure also provides for the use of these zeolite materials as a catalyst and a method of preparing said catalyst. The PIDC-type zeolites or STT-type zeolite materials may be used as a catalyst, such as in Selective Catalytic Reduction (SCR) applications.

Abstract: A catalyst support material (D-CZMLA) with oxygen storage capacity corresponds to the formula vD:x(Ce1-wZrwO2):yM:zL:(1-v-x-y-z)Al2O3, wherein w is a molar ratio between 0.1-0.8 and v, x, y, and z are weight ratios, such that v is between 0.005-0.15, x is between 0.05-0.80, and y and z are between 0.001-0.10. M is an interactive promoter for oxygen storage, L is a stabilizer (L) for the Al2O3 support; and D is an oxidizing dopant. The catalyst support material can be incorporated into a wash coat that combines platinum group metals (PGM), an adhesive, and a mixture of (α)RE-Ce—ZrO2+(β)CZMLA+(1−α−β)RE-Al2O3, wherein RE-Ce—ZrO2 is a rare earth element stabilized ceria zirconia having a weight ratio (α) between 0-0.7; CZMLA is the doped catalyst support material having a weight ratio (β) between 0.2-1, such that (α+β)≤1; and RE-Al2O3 is rare earth element stabilized alumina having a weight ratio equal to (1−α−β).
