Abstract
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.
Claims20
An electrochemical cell, comprising:
- a cathode, the cathode including a total amount of a cathode active material that can store a total number of cathodic electrons;
- an anode, the anode including a total amount of an anode active material that can store a total number of anodic electrons;
- an electrolyte, the electrolyte including a solvent and a salt dissolved in the solvent;
- the electrolyte being in contact with the cathode;
- wherein the cathode active material is transformed into a discharge product during or after a discharge of the electrochemical cell;
- a solubility of the cathode active material in the electrolyte is less than a solubility of the discharge product in the electrolyte;
- the total number of anodic electrons is less than the total number of cathodic electrons;
- the total amount of the anode active material is less than the total amount of the cathode active material;
- and
- wherein the cathode, the anode, and the electrolyte are enclosed within a sealed and gas-impermeant cell housing.
