SELF-CHARGING ELECTROCHEMICAL CELLS

Self-charging electrochemical cells, including self-charging batteries that incorporate such self-charging electrochemical cells, the electrochemical cells including a cathode including a cathode active material, an electrolyte including a solvent and a salt dissolved in the solvent, the electrolyte being in contact with the cathode, where the cathode active material is transformed into a discharge product during or after a discharge of the self-charging electrochemical cell and a solubility of the cathode active material in the electrolyte is less than a solubility of the discharge product in the electrolyte.
