1. A cell for use in an electrochemical cell, 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 the anode when the cell is charging;
a negative electrode, the negative electrode comprising an active material as an 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 electrolyte from the cathode and the remaining portion of the electrolyte; wherein the separator is permeable to the reversible flow of lithium ions there through;
wherein at least one of the cathode, the anode, the electrolyte, and the separator includes an inorganic additive that absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride (HF) that become present in the cell; the inorganic additive being one or more metal aluminates;
wherein the inorganic additive further includes one or more doping elements selecting from Li, Na, Al, Mn, Sm, Y, Cr, Eu, Er, Ga, Zr, and Ti.
