Photonic crystal electrical property indicator
First Claim
1. A photonic crystal electrical property indicator for a battery comprising:
- an electrically conductive working electrode and an electrically conductive counter electrode, the working and counter electrodes being spaced apart;
an electrically-responsive photonic crystal material in contact with at least one of the working and counter electrodes;
an ionically conductive electrolyte provided between the working and counter electrodes, the electrolyte being in electrical communication with both the working and counter electrodes and the photonic crystal material; and
electrical conductors in electrical communication with the working and counter electrodes for connecting the indicator to terminals of the battery;
wherein a charge-storage material is provided on at least one of the working and counter electrodes, or within the ionically conductive electrolyte, wherein the charge storage material has different thicknesses in at least two portions of the indicator,wherein the at least two portions have reflectance spectra that are responsive to a change in at least one electrical property of the battery, the reflectance spectra of the at least two portions differing, thereby providing at least two different optically detectable indications of the at least one electrical property of the battery.
