Abstract: A urea concentration identification method is provided. By providing an identical sine-wave AC signal to each of the urea concentration identification devices placed in urea solutions of different concentrations, different impedance values are output by the urea concentration identification devices since the urea solutions of different concentrations have different electrical interactions with the electrodes of the urea concentration identification device. Differences of the impedance output by the urea concentration identification device function as a data set for determining the concentration of the urea solution to be determined.

Abstract: A liquid concentration detecting device including a first substrate, a first temperature sensing element and a concentration sensor is provided. The first temperature sensing element and the concentration sensor are respectively disposed on opposite first surface and second surface of the first substrate. The concentration sensor includes a second substrate, a porous element, a heating element and a second temperature sensing element. The second substrate is disposed above the second surface. A portion of the liquid flows into the concentration sensor through the porous element, and the heating element heats the liquid in the concentration sensor. The second temperature sensing element measures the temperature variation of the liquid in the concentration sensor. The measured temperature and the temperature variation are compared to deduce a concentration of the liquid under detection.

wherein M is a trivalent ion or a pentavalent ion, M′ is a bivalent ion, x=0-1, y=0-1.5, and the precursor structure includes a pyrochlore phase. Since the pyrochlore phase may be transformed into the garnet phase through a lithiation process and the phase transition temperature is lower (e.g., 500-1000° C.), the precursor structure may be co-fired with the cathode material (e.g., lithium cobalt oxide (LiCoO2)) to form a thin lamination structure. That is, the thickness of the solid electrolyte may be effectively reduced, thereby improving the ionic conductivity of the solid electrolyte ion battery.
