Abstract:
1. A system, comprising: an electrochemical energy device comprising an electrode material and a guest species contained inside a cell wall; one or more optical fibers having a first portion disposed on the electrochemical energy device; a light source configured to provide light onto the one or more optical fibers; at least one optical sensor disposed on the one or more optical fibers adjacent to the first portion, the optical sensor configured to modulate the light in accordance with a measured operating parameter associated with an operating condition of said electrochemical energy device such that at least one light signal generated by said at least one optical sensor includes operating parameter data associated with said measured operating parameter; an analyzer coupled to a second end of said one or more optical fibers, the analyzer configured to receive said at least one light signal from said one or more optical fibers, and convert said at least one light signal into corresponding operating parameter data signals; and a processor configured to detect a present intercalation stage change of the electrochemical energy device by analyzing said operating parameter data signals, said present intercalation stage change being caused by migration of the guest species within the electrode material.
