Nickel oxide laminated

Suitable materials for the anode in electrochemical perfluorinations are nickel plate, nickel foam5 or nickel oxide laminated metals.6 Materials for the cathode are nickel or steel. Platinum or rhodium is commonly used29 for partial electrochemical fluorination. Nickel electrodes are... 

An electrochromic device embodies a number of superimposed layers on a transparent substrate or between two transparent substrates, and optical transmittance is altered when an electrical potential is applied so that charge is shuttled between layers serving in the same way as anodes and cathodes in an electrical battery. One specific design with a five-layer construction shown in Figure 30 uses cathodically coloring WO3 and anodically coloring nickel oxide joined by an ion-conducting electrolytic laminate. A potential of a few volts, preferably supplied by solar cells, is applied between... 

Lampert and coworkers [36] have used a modified amorphous PEO-LiCFaSOs electrolyte for the realization of WO3 laminated windows using several types of counter-electrodes, such as niobium oxide, nickel oxide and a new class of solid redox polymerization electrodes [63]. These latter electrodes have an advantage over inorganic layers in that they can be tailored to the electrochromic material and ion specifically. Figure 8.18 illustrates the optical transmittance of a EW made of WOa/modified a-PEO/ion storage polymer [63].

Lead-clad steel sheet (cold rolled lead sheet bonded to steel sheet) and other composite materials (using laminates, for instance) improve on the mechanical properties of lead, whilst retaining its other inherent advanu es. These are often tailormade to suit particular applications. Another newer material is dispersion strengthened lead (DSL). Here, foreign materials (such as copper, nickel, alumina or natural lead oxide) are uniformly dispersed through the lead sheet by powder metallutgical methods.
