The ability to use safely an alkali-metal anode in a rechargeable battery would increase the energy density and cycle life of a battery cell for a given cathode. The talk will illustrate the successful realization of dendrite-free potassium, sodium, and lithium rechargeable batteries having liquid, polymer, or solid electrolytes. Some features of a remarkable glass electrolyte having a Li⁺ or Na⁺ cation conductivity δ_i > 10^-2 S cm^-1 at 25°C, stability on contact with metallic lithium or sodium, and a window to 9 eV will also be presented.
