Abstract: A cell 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. At least one of the cathode, the anode, the electrolyte, and the separator includes an inorganic additive in the form of a metal aluminate or a mixture of metal aluminates that absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride (HF) 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. The inorganic additive may also be incorporated as a coating applied to the internal wall of the housing.

Abstract: A separator for use in an electrochemical cell, such as a lithium-ion secondary battery, that includes a plurality of first inorganic particles, one or more second inorganic particles, a polymeric binder, wherein the weight ratio of the first inorganic particles to the second inorganic particles is in the range from 1:99 to 99:1 and the weight ratio of the combined first and second inorganic particles to the polymeric binder is in the range from 50:50 to 99:1. The inorganic particles being a type of Li-exchanged zeolite having a lithium (Li) concentration in the range of 0.1 wt. % to 20 wt. % and a sodium (Na) concentration that is lower than 5 wt. %, based on the overall weight of the Li-exchanged zeolite. The second inorganic particles being different in composition than the first inorganic particles and having a sodium (Na) concentration in the range of 0.005 wt. % to 1.0 wt. %.
