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.
