Hybrid electrodes for batteries are disclosed having a protective electrochemically active layer on a metal layer. Other hybrid electrodes include a silicon salt on a metal electrode. The protective layer can be formed directly from the reaction between the metal electrode and a metal salt in a pre-treatment solution and/or from a reaction of the metal salt added in an electrolyte so that the protective layer can be formed in situ during battery formation cycles.

Protective layers for metal electrode batteries

A sodium-ion conducting (e.g., sodium-sulfur) battery, which can be rechargeable, comprising a microporous host-sulfur composite cathode as described herein or a liquid electrolyte comprising a liquid electrolyte solvent and a liquid electrolyte salt or electrolyte additive as described herein or a combination thereof. The batteries can be used in devices such as, for example, battery packs.
