“…The cyclic voltammetry was compared to voltammograms recorded in other publications in similar conditions for other gas diffusion air electrodes [32,33,34,35,36]. Figure 6 shows the data for two scans of the Ni/Fe + Pd air electrode, from the equilibrium potential (where j = 0) of +0.33 V vs. Hg/HgO, in the negative potential direction (ORR) and the positive direction (OER), compared with data from the literature.…”

The development of air-breathing cathodes, which utilise atmospheric oxygen, enables the construction of lightweight, high energy density metal-air batteries and fuel cells. Air electrodes can be very lightweight and thin because the active material, oxygen, does not need to be stored inside the cell. However, air electrodes are restricted by poor reaction kinetics and low activity of many catalysts towards the oxygen evolution and reduction reactions. In addition, it is a challenge to maintain chemical and mechanical stability of the catalyst and supporting materials at oxidising currents under the strong alkaline conditions commonly used, and gas evolution. This paper reports a novel bifunctional oxygen electrode with remarkable stability, able to perform at current densities up to 1,000 mA cm -2 and withstand 3,000 cycles continuously. The electrode is catalysed by a mixture of Pd/C and mixed nickel-iron hexocyanoferrate, which have high activities towards the ORR and OER reactions, respectively.

“…Therefore, its treatment 3 temperature and the processing time are significantly lower than those of conventional preparation routes. One can also expect to produce very fine and crystalline perovskitetype oxide powders by using this SHS method [26][27][28].Other combustion techniques are widely used to synthesize solid catalyst [29,30]. Among them, the solution combustion synthesis (SCS) method is used to synthesize perovskite-type oxides [31].…”

The decomposition of La[Fe(CN) 6 ] and La [Co(CN) 6 ] under different atmospheres has been analyzed by thermogravimetry (TG) and differential thermal analysis (DTA). In addition, the decomposition temperature at different sample locations was monitored for sample masses around 2 g of La[Fe(CN) 6 ] and La[Co(CN) 6 ], when they were calcined for 1 h at temperatures ranging from 200 to 400 ºC in a controlled gas-flow system.Results showed that, for sample large enough of these cyano complex precursors undergo combustion when are decomposed under oxygen atmosphere. X-ray diffraction 2 revealed that perovskite-type oxides crystallize due to the overheating of the process. As a result, it has been possible to produce LaFeO 3 and LaCoO 3 perovskite-type oxide powders by SHS under oxygen atmosphere using La[Fe(CN) 6 ] and La[Co(CN) 6 ] as a precursor. The effect of the ignition temperature has been investigated. The specific surface area of the perovskite-type oxides produced via SHS using heteronuclearcyano metal complex as a precursor is significantly higher than that of other LaMO 3 produced using the same technique but obtained from other type of precursors.

This paper describes the glycine-nitrate-based solution combustion synthesis of LiNi 0.5 Mn 1.5 O 4 as a high-voltage cathode material for lithium-ion batteries. The morphology, size, and crystallinity of the products were dependent on the synthesis conditions like glycine amount and calcination temperature and duration, as investigated in particular by X-ray diffraction and scanning electron microscopy, which likewise influenced their electrochemical properties. The electrochemical performance was characterized by galvanostatic charge-discharge cycling. The product obtained at a glycine/nitrate ratio of 1, which was calcined at 800 ºC for 24 h, indicated the best charge-discharge cycling performance. The sample showed an initial discharge capacity of 124.9 mAh/g and could retained 97.20% of the capacity after 50 cycles at a charge-discharge rate of 1 C. The sample also exhibited a good high-rate capability, indicating a high discharge capacity of 98 mAh/g at a rate of 10 C.
