Abstract
A process for charging a discharged electrochemical cell includes applying a voltage bias to the discharged electrochemical cell; and illuminating the cathode with a light source.
Claims15
A process for charging a discharged electrochemical cell, the process comprising:
- applying a voltage bias to the discharged electrochemical cell;
- and
- illuminating the cathode with a light source;
- wherein:
- under illumination with the light source the discharged electrochemical cell is charged to a predetermined state in less time than the same discharged electrochemical cell in the absence of illumination;
- the discharged electrochemical cell comprises a cathode, an anode, and a non-aqueous electrolyte;
- and
- the electrochemical cell is a lithium ion battery, a sodium ion battery, a magnesium ion battery, or a sulfur battery.
