Topological state of matter and lithium batteries are currently two hot topics in science and technology. Here we combine these two by exploring the possibility of using all-carbon-based porous topological semimetal for lithium battery anode material. Based on density-functional theory and the cluster-expansion method, we find that the recently identified topological semimetal bco-C16 is a prom...

Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In this study, we discover that doping graphene oxide into...

Anode-supported micro-tubular solid oxide fuel cell (SOFC) offers many advantages over the electrolyte and cathode-supported confgurations in terms of simplicity, reliability, and efciency. In such design, the anode substrates should possess a highly porous structure, provide active sites reaction as well as serving good mechanical strength. This structure is desired to ...

Unlike the more established lithium-ion based energy storage chemistries, the complex intercalation chemistry of multivalent cations in a host lattice is not well understood, especially the relationship between the intercalating species solution chemistry and the prevalence and type of side reactions. Among multivalent metals, a promising model system can be based on nonaqueous Zn ion chemistry...

Abstract Fe–Ni invar alloy (Fe 64–Ni 36 wt%) has a very low coefficient of thermal expansion (CTE) than any other metals. For this reason, it been used as fine metal mask (FMM) in RGB patterning OLED manufacture process. However, the resolution display is getting higher, thickness FMM thinner and then conventional extruded sheet cannot be directly. The electrodeposition can alternative for fabr...

We report on a simple strategy for the direct synthesis of a thin film comprising interconnected NiO nanoparticles deposited on both sides of a graphene sheet via cathodic deposition. For the co-electrodeposition, graphene oxide (GO) is treated with water-soluble cationic poly(ethyleneimine) (PEI) which acts as a stabilizer and trapping agent to form complexes of GO and Ni2+. The positively cha...

The electrochemical deposition of Cu into 0.12 cm and 60 μm thick, highly porous 65 vol % Ni/yttriastabilized zirconia (YSZ) cermets was investigated. An electrochemical cell in which the electrolyte solution was allowed to flow through a porous Ni/YSZ substrate was used to eliminate mass-transfer limitations and to determine the conditions for which the potential drop in the electrolyte soluti...

The recovery of selenium from Iranian sar-cheshmeh copper anode slime has been investigated. Copper anode slimes are containing varying precious metals, such as: gold, silver, selenium and tellurium. They are being extracted as a by-product in the production process. Arsenic and antimony that present in anode slimes dissolved in 0.4 M KOH. Then, the alkaline roasting of anode slimes in the pres...

The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

according to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of cu, ag, au, pb and se. in this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. silver was separated from anode slime by using of hno3 and hcl. x-ray fluorescence spectroscopy (xrf) was used to characterize anode sl...
