TL;DR: This systematic study provides insight into the rational design of NMC-based cathode materials with a desired balance between thermal stability and high energy density.

TL;DR: In this article, MnO2 was applied to carbon nanotubes (CNTs) by simple immersion of the CNTs into a KMnO4 aqueous solution.

TL;DR: In this article, the effect of electrodeposition conditions such as cathodic current density and concentration of Ni(NO 3 ) 2 solution on the surface morphology of NiO x thin film electrodes was examined and found to have a significant effect on the surfaces morphology of the deposited films.

TL;DR: In this paper, an in situ technique that combines time-resolved synchrotron X-ray diffraction and mass spectroscopy was used to provide direct correlation between structural changes and the evolution of gas that occurs during the thermal decomposition of (over)charged cathode materials used in lithium-ion batteries.

TL;DR: In this article, a Birnessite-type manganese dioxide (MnO2) is coated uniformly on carbon nanotubes (CNTs) by employing a spontaneous direct redox reaction between the CNTs and permanganate ions (mnO4−) and the initial specific capacitance of the MnO2/CNT nanocomposite in an organic electrolyte at a large current density of 1.A.g−1 is 250 ǫ g−1.
