ABSTRACT:
Cells, especially solid state rechargeable lithium ion-containing cells having significantly improved cell shelf-life, cycle life and reduced impedance growth. A non-cathode active lithium compound containing one or more non-metallic elements, such as Li.sub.2 CO.sub.3 and Li.sub.2 B.sub.4 O.sub.7, substantially insoluble in the non-aqueous electrolyte of the cell, is dispersed throughout the cathode and is further dispersed within at least one of the anode and separator.
