Abstract
Disclosed is a method of: providing an electrochemical energy storage device having a first electrode and a second electrode; and simultaneously: a) maintaining the first electrode and a first temperature; b) maintaining the second electrode at a second temperature; and c) charging or discharging the device. The coolest portion of the second electrode is at least 1° C. warmer than the warmest portion of the first electrode.
Claims3
A method of operating a battery comprising:
- providing the battery comprising a cathode and an anode and simultaneously:
- a) maintaining the cathode at a first temperature;
- b) maintaining the anode at a second temperature;
- and
- c) charging the battery;
- wherein the anode comprises a coolest portion;
- wherein the cathode comprises a warmest portion;
- wherein the coolest portion of the anode is at least 1° C. warmer than the warmest portion of the cathode;
- wherein the anode comprises metal plating;
- and
- wherein the charging the battery converts a portion of the metal plating to metal ions.
A method of operating a lithium ion or lithium metal battery comprising:
- providing the lithium ion or lithium metal battery comprising a cathode and an anode and simultaneously:
- a) maintaining the cathode at a first temperature;
- b) maintaining the anode at a second temperature;
- and
- c) charging the battery;
- wherein the anode comprises a coolest portion;
- wherein the cathode comprises a warmest portion;
- wherein the coolest portion of the anode is at least 1° C. warmer than the warmest portion of the cathode;
- wherein the anode comprises lithium metal and is free of metal plating.
