Mechano-Chemo-Electrochemically Booming Nickel-Rich Layered Cathode Electrochemical Performance

ACS Applied Materials & Interfaces
The practical application of nickel-rich layered transition metal oxide is hampered by its fast capacity decay, deriving from the side reactions with electrolyte, crack formation caused by volume variation, and phase change near the surface during the charging/discharging processes.

Superior electrochemical performance of NiS/Ni obtained via electrochemical corrosion

Materials Letters, 2016
Abstract NiS is successfully grown on Ni foam via an in situ electrochemical corrosion method. It is proposed that H2O2 can act as cathodic depolarizer that promotes the corrosion of Ni, which is crucial for the formation of NiS. The NiS shows flower-like morphology with mean size about 2 µm, consisting of flocky particles with size range from 500 nm

Electrochemical reduction of graphene oxide and its electrochemical capacitive performance

Journal of Solid State Electrochemistry, 2013
A convenient method for the production of graphene is developed using the electrochemical reduction of graphite oxide (GO) in solution without assembling it onto the electrode. The samples were examined by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and Raman spectroscopy.

Electrochemical performance of granulated titania nanoparticles

Journal of Power Sources, 2004
Abstract The electrochemical performance of Li-ion insertion into electrodes made of various sizes of anatase titania nanoparticles embedded in larger granulated entities (1–10 μm) is investigated. The granules are formed by spray drying of a suspension containing titania nanoparticles made by hydrolyzing titanium tetraisopropoxide (TTIP).
