Abstract Through a sol-gel method, honeycomb-like Na 3 V 2 (PO 4 ) /C cathode material for sodium-ion batteries was synthesized from spent electroless nickel plating bath. The obtained exhibited excellent electrochemical properties, with the initial discharge capacity of 108.3 mAh·g −1 at 0.2 C and retention 99.3% after 300 cycles, which comparable to that powders prepared chemical reagents. Th...

In this work the effects of various methods of agitation on the properties of electroless Ni-P-MoS2 composite coatings were investigated. Magnetic stirring as well as purging the solution with gas (Air, Oxygen, Nitrogen) were used. Plating rate, chemical composition, MoS2 distribution, and hardness of the deposit were measured. Topography of coating was studied with metallography and scanning e...

We report the experimental observation of traveling fronts during the electroless deposition of copper on passive steel substrates. The low-carbon steel samples are passivated in nitric acid prior to the plating experiment, thus creating a thin, protective oxide layer on the steel surface. The deposition experiments are carried out from slightly acidic (pH 3.2) copper sulfate solution and coppe...
