Abstract

Described embodiments include a system and a method. A system includes a controllable electrochemical cell configured to output pulsed electric power. The controllable cell includes an electrolyte, and a first working electrode configured to transfer electrons to or from the electrolyte. The system includes a second working electrode configured to transfer electrons to or from the electrolyte. The system includes a gating electrode spaced-apart from the second working electrode and configured if biased relative to the second working electrode to modify an electric charge, field, or potential in the space between the electrolyte and the second working electrode. The system includes a control circuit configured to establish a nonlinear voltage-current property of the controllable cell in response to an externally originated trigger signal.

Dependent claims

A system comprising:

a controllable electrochemical cell configured to output pulsed electric power, the controllable cell including:
(a) an electrolyte;
(b) a first working electrode configured to transfer electrons to or from the electrolyte;
(c) a second working electrode configured to transfer electrons to or from the electrolyte;
and
(d) a gating electrode spaced-apart from the second working electrode and configured if biased relative to the second working electrode to modify an electric charge, field, or potential in the space between the electrolyte and the second working electrode;
an external trigger signal source programmed to provide an externally originated trigger signal for biasing the gating electrode to establish a nonlinear voltage-current property of the controllable cell;
and
a control circuit programmed to establish the nonlinear voltage-current property of the controllable cell by biasing the gating electrode in response to the externally originated trigger signal;
wherein the external trigger signal source is a source other than an external load coupled with the controllable cell.
