TL;DR: The efficacy of composite Li-ion battery cathodes made by mixing active materials that possessed either high-rate capability or high specific energy was examined in this article, where the cathode structures studied contained carbon-coated LiFePO 4 and either Li[Li 0.17 Mn 0.58 Ni 0.25 ]O 2 or LiCoO 2.

TL;DR: In this article, the transient natural convection heat transfer problem between two horizontal isothermal cylinders is formed within the Boussinesq approximation and solved numerically through the vorticity-stream function approach.

TL;DR: In this paper, the behavior of corrosive sulfur in mineral oils is examined in terms of the failures observed in transformers, the surfaces of the copper sulfide covered conductors and degraded paper insulating tapes.
Abstract: The behavior of corrosive sulfur in mineral oils is examined in terms of the failures observed in transformers, the surfaces of the copper sulfide covered conductors and degraded paper insulating tapes. The role of dissolved gas analysis (DGA) in the evaluation of the risk of copper sulfide formation is described. The degree of corrosiveness of some sulfur compounds is examined and compared using a Kraft paper wrapped-copper test (standard IEC 62535). The occurrence of DBDS as the most relevant corrosive compound is compared with the presence of other corrosive species in insulating mineral oils. A number of mitigation techniques for corrosive sulfur are described and evaluated.

TL;DR: In situ and ex situ scanning electron microscopy of nano Si and SiO anode particles was carried out during the first cycles, and at various stages of charge as discussed by the authors, providing a new insight into the micro-structural evolution of the particles as a function of their size, and into the'mechanical' resistance upon important volume change upon phase transformation of these anodes.

TL;DR: In this article, the authors present the results of an experimental study on the corona characteristics of single and bundle conductors under impulse voltage conditions in a large cage, most of which were performed with positive impulses.
Abstract: This paper presents the results of an experimental study on the corona characteristics of single and bundle conductors under impulse voltage conditions in a large cage. Both lightning and switching impulses were used for the tests, most of which were performed with positive impulses. The influence of artificial rain on the corona characteristics was also studied. An analysis of the experimental results is presented with emphasis on the corona onset voltage gradient, the apparent change in the capacitance of the line conductor and the energy dissipated by corona. A simple analog circuit is suggested to simulate the influence of impulse corona on waves propagating along line conductors.
