The first practical SSLBs were Li-I 2 batteries, which are now utilized in cardiac pacemakers. Their electrolytes are crystalline LiI that forms spontaneously (in-situ) between a cathode [e.g., poly(2-vinylpyridine)] and a Li metal anode. However, the cell voltage of a Li-I 2 battery is approximately 3 V, and the Li + conductivity of LiI is very low, …
