The electrodeposition of Ni-MoO2 composite coatings is a specific process taking place under defined hydrodynamic conditions. In this work the influence of hydrodynamics, current density, and MoO2 concentration on the electrodeposition of Ni-MoO2 coatings from a suspension of MoO2 particles in a Watt’s type bath were investigated by comparison of their polarization characteristics for the hydro...

Fast charging of lithium-ion (Li-ion) batteries makes it susceptible to lithium plating. In this study, we report the correlation between capacity loss and cell impedance changes in battery due electrodeposition. Li-ion pouch cells with nickel-manganese-cobalt cathode graphite anode were charged at rates varying from 0.5C 6C. The voltage evolution immediately after was monitored identify C-rate...

The electrodeposition of soft, high magnetic moment alloys has become the critical fabrication step in manufacturing of magnetic recording heads. The need for ultimately high magnetic moment alloys (2.4 T CoFe) and the electrodeposition process capable of delivering magnetic structures with dimension in the range of several tens of nanometers are the new tasks that have to be addressed if the f...

A review on pulse and pulse reverse techniques for electrodeposition have been attempted. Pulse electrodeposition (PED) of some metals and lloys are reported. The effects of mass, transport, electrical double layer pulse parameters and current distribution on surface roughness and orphology are presented. Applications, advantages and disadvantages of PC and PRC techniques are discussed along wi...

Al-based batteries are considered an attractive alternative to Li metal due the use of Al as anode with lower cost, reactivity and larger abundance compared Li. Despite aforementioned attributes, few electrolytes permit reversible electrodeposition at room temperature. Thus, for last 30 years, expensive imidazolium-based ionic liquids have dominated field. Even though extensive research has bee...

Rough Li plating, low ionic conductivity, and thermal stability of conventional electrolytes post-primary challenges for achieving reliable high-capacity rechargeable lithium batteries, which metal is frequently proposed as the most promising anode material. Conventional low-polarity commercial polypropylene/polyethylene separators fail to support application high-energy-density anodes due thei...

To reach high energy density and excellent cycle stability, an asymmetric supercapacitor device combining a high-power electric double-layer capacitor (EDLC) anode battery-type cathode has been designed fabricated. A binder-free strategy was used to prepare by coating graphene (G) on Ni foam (Ni), then electrodepositing MnO2, followed calcination process. The potentiodynamic (PD) electrodeposit...

Electrodeposition of zinc on mild steel in acid chloride solution using as additive, different concentrations of ananas comosus (pineapple) juice extracts, was investigated. Different additive concentrations, plating time, and constant pH conditions were used for the experiments. The electrodeposition of zinc on mild steel was performed using a DC – supply. The surface of the plated steel was e...

ZnO films can be electrodeposited cathodically from aqueous zinc salt solutions in the presence of oxidants like O2 [1]. The electrodeposition of nanoporous ZnO was first demonstrated by addition of water-soluble organic dye molecules with anionic groups such as –SO3 or – COO, which adsorb on the growing ZnO surface, to the electrodeposition bath [2]. More recently, addition of amphiphilic mole...
