Abstract
An electrochemical device having a liquid electrolyte which includes a protic solvent, an anode electrode disposed in contact with the liquid electrolyte, and a cathode electrode disposed in contact with the liquid electrolyte. A membrane which interrupts the transport of ions between the electrodes at a predetermined temperature is disposed in the liquid electrolyte between the anode electrode and the cathode electrode. In this way, electrochemical devices such as batteries, fuel cells, electrolyzers, and sensors, which may overheat during use and cause a fire or explosion, are precluded from overheating.
Claims20
An electrochemical device comprising:
- a liquid electrolyte comprising a protic solvent;
- an anode electrode disposed in contact with said liquid electrolyte;
- a cathode electrode disposed in contact with said liquid electrolyte;
- and
- ion transport interruption means for interrupting transport of ions between said electrodes at a predetermined temperature disposed in said liquid electrolyte between said anode electrode and said cathode electrode.
In an electrochemical device having a liquid electrolyte, an anode electrode disposed in contact with said liquid electrolyte, and a cathode electrode disposed in contact with said liquid electrolyte, a method for preventing a fire or explosion in said electrochemical device comprising the steps of:
- inserting a membrane having temperature-dependent ion permeability into said liquid electrolyte between said anode electrode and said cathode electrode.
