DTIC ADA176283: History of Solid State Batteries.

Historically, batteries have combined liquid electrolytes with solid electrodes because solid electrolytes were to resistive and could not accommodate the volumetric changes associated with the cell reactions. Solid materials utilized as battery electrolytes include: 1) simple ionic salts - Silveriodide; 2) double salt compounds - Rubidic Silver Iodide; (3) dispersed phase solid electrolytes - LiI (AL2)3); (4) ceramic compounds - Sodium - Beta - AL2)3; 5) in-situ formed electrolytes - Lithium iodide; 6) glasses - LiI-Li2S-P2S5; 7) polymer electrolytes - (PEO)8LiCL04). Commercialization has been limited because of performance and cost factors. Keywords: solid state battery.
