1. A cell for use in a lithium-ion secondary battery, the cell comprising:
a positive electrode, the positive electrode comprising an active material as a cathode for the cell and a current collector that is in contact with the cathode; wherein lithium ions flow from the cathode to an anode when the cell is charging;
a negative electrode, the negative electrode comprising an active material as the anode for the cell and a current collector that is in contact with the anode; wherein lithium ions flow from the anode to the cathode when the cell is discharging;
a non-aqueous electrolyte positioned between and in contact with both the negative electrode and the positive electrode; wherein the non-aqueous electrolyte supports the reversible flow of lithium ions between the positive electrode and the negative electrode; and
a separator placed between the positive electrode and negative electrode, such that the separator separates the anode and a portion of the non-aqueous electrolyte from the cathode and the remaining portion of the non-aqueous electrolyte; wherein the separator is permeable to the reversible flow of lithium ions there through;
wherein at least one of the non-aqueous electrolyte and the separator includes an inorganic additive that absorbs moisture, free transition metal ions, and hydrogen fluoride (HF) that become present in the cell; the inorganic additive being one or more types of a zeolite having a zeolite framework of CHA, CHI, FAU, LTA or LAU with a silicon (Si) to aluminum (Al) ratio ranging from about 2 to about 50; the inorganic additive having a surface area that is in the range of about 10 m2/g to about 1000 m2/g, a pore volume in the range of 0.1-2.00 cc/g, as well as a sodium concentration that ranges from 0.1 wt. % to about 1.0 wt. % and a lithium concentration that ranges from 2.5 wt. % to 10 wt. % based on the overall weight of the inorganic additive;
wherein the cell has a loss in discharge capacity after 100 cycles of C/2 charge-and-discharge at 25° C. of about 0.5%.
