Abstract
The embodiments described herein relate to a system including an electrochemical cell assembly including an electrolyte composition, and a transducer disposed proximate to the electrolyte composition. The transducer is configured to be selectively activated to deliver an amount of energy to the electrolyte composition to increase a shear thickening of the electrolyte composition. The electrolyte composition includes an electrolyte solvent, an electrolyte salt, and shear thickening particles.
Claims22
An electrochemical cell assembly, comprising:
- an anode disposed on an anode current collector;
- a cathode disposed on a cathode current collector;
- an electrolyte composition, at least a portion of the electrolyte composition disposed between the anode and the cathode, the electrolyte composition including an electrolyte solvent, an electrolyte salt, and a plurality of shear thickening particles;
- and
- a transducer physically and/or communicatively coupled to at least one of the anode current collector or cathode current collector, the transducer configured to be selectively activated to deliver an amount of energy to the electrolyte composition via the at least one of the anode current collector or cathode current collector to cause the shear thickening particles to increase the viscosity of the electrolyte composition, the transducer configured to be selectively activated in response to receiving an event signal that is generated in response to an external event.
