Abstract:
A metal oxygen battery system. The metal oxygen battery storage system includes a metal oxygen battery, which includes a cathode and an anode including a lithium metal material. The metal oxygen battery system further includes an oxygen containment unit including an oxygen storage material and external to the metal oxygen battery. The metal oxygen battery system also includes a reversible closed-loop in fluid communication with the metal oxygen battery and the oxygen containment unit, which are spaced apart from each other.
Abstract:
In one or more embodiments, an electrochemical device includes a substrate having a substrate surface; an amorphous metal oxide layer supported on the substrate surface; and a noble metal catalyst supported on the amorphous metal oxide layer to form a catalyst layer. The amorphous metal oxide layer may contact only 25 to 75 percent of the substrate surface. The amorphous metal oxide layer may include less than 10 weight percent of crystalline metal oxide. In certain instances, the amorphous metal oxide layer is substantially free of crystalline metal oxide.
Abstract:
A catalyst assembly having a substrate including an intermetallic compound of W and Ir. The weight ratio of W to Ir is in a range between a first ratio and a second ratio. A catalyst includes at least one noble metal is supported on and contacts the substrate. The first ratio may be in the range of 48:52 and the second ratio may be in the range of 51:49.
