Abstract
An electrochemical cell of a secondary lithium ion battery includes lithium ion-exchanged zeolite particles or 'lithiated zeolite particles' positioned along at least a portion of a lithium ion transport path through the electrochemical cell. The lithiated zeolite particles may be positioned within the lithium ion transport path through the electrochemical cell, for example, by being distributed throughout an electrolyte disposed between confronting anterior surfaces of a negative electrode and a positive electrode. Additionally or alternatively, the lithiated zeolite particles may be positioned within the lithium ion transport path through the electrochemical cell by being distributed throughout or deposited as a coating layer on the negative electrode, the positive electrode, and/or a porous separator sandwiched between the confronting anterior surfaces of the negative and positive electrodes.
