Instrumented fluid-surfaced electrode

摘要

An electrochemical device (such as a battery) includes at least one electrode having a fluid surface and one or more sensors configured to detect an operating condition of the device. Fluid-directing structures may modulate flow or retain fluid in response to the sensors. An electrolyte within the device may also include an ion-transport fluid, for example infiltrated into a porous solid support.

主权项

1. An electrochemical device, comprising:
two electrodes; an electrolyte that conducts an ionic current from a first electrolyte surface in contact with one of the electrodes to a second electrolyte surface in contact with another of the electrodes, a first sensor located at an interface between one of the electrodes and the electrolyte, which first sensor detects an operating condition of the electrochemical device; wherein
at least one of the electrodes is a fluid-surfaced electrode including an electrochemically active fluid layer disposed over a solid support, a surface of the electrochemically active fluid layer being in direct physical contact with the electrolyte; andthe solid support includes an electrical control region separating two electrically distinct regions of the at least one fluid-surfaced electrode.
