A critical analysis of possible (including some newly proposed) definitions of the vitreous state and the glass transition is performed and an overview of kinetic criteria of vitrification is presented. On the basis of these results, recent controversial discussions on the possible values of the residual entropy of glasses are reviewed. Our conclusion is that the treatment of vitrification as a process of continuously breaking ergodicity with entropy loss and a residual entropy tending to zero in the limit of zero absolute temperature is in disagreement with the absolute majority of experimental and theoretical investigations of this process and the nature of the vitreous state. This conclusion is illustrated by model computations. In addition to the main conclusion derived from these computations, they are employed as a test for several suggestions concerning the behavior of thermodynamic coefficients in the glass transition range. Further, a brief review is given on possible ways of resolving the Kauzmann paradox and its implications with respect to the validity of the third law of thermodynamics. It is shown that neither in its primary formulations nor in its consequences does the Kauzmann paradox result in contradictions with any basic laws of nature. Such contradictions are excluded by either crystallization (not associated with a pseudospinodal as suggested by Kauzmann) or a conventional (and not an ideal) glass transition. Some further so far widely unexplored directions of research on the interplay between crystallization and glass transition are anticipated, in which entropy may play-beyond the topics widely discussed and reviewed here-a major role.

“…Repeating conversion processes during charging-discharging would result in pulverization of the anode and finally destroy of its initial structure [28][29][30][31]. Additionally, some typical transition metal phosphides are rather compact in phase structures, which is the reason why these materials are resistive to environmental corrosion.…”

“…However, the dense packing in electrode structures is not helpful for fast lithiation / delithiation of the anode material, leading to low electrochemical response of the battery system. Among the transition metal phosphides, Ni 3 P reacts with Li + at an average voltage about 1 V and induces flat charge and discharge curves separated by about 0.4 V [29][30][31]. Great endeavor has been made in order to improve the electrochemical performance of the anode material based on Ni 3 P powder.…”

Nickel phosphide (Ni 3 P) is a promising anode material for lithium-ion batteries owing to its high specific capacity, though significant improvement in its cycling stability is highly desired. Here we propose an effective and low-cost solution via a three-dimensional construction of porous NiO covered Ni 3 P films over a substrate of Ni foam, through electroless plating of P-rich Ni 3 P and subsequent in situ oxidation in air. The in situ oxidation of P-rich Ni 3 P resulted in the formation of nano porous NiO capping layer.Remarkable enhancement in the cycling stability of such a composite anode was thus realized. The initial discharge capacity for a CR2016-type coin cell was as high as 920 mA h g -1 , and there was still a reversible capacity of 550 mA h g -1 after 60 cycles at a current density of 38.8 mA g -1 . The presence of porous NiO capping layer changed the lithiation path and significantly improved the cycling performance. The decreased resistance in charge transport due to the existence of adequate channels for Li ions diffusion also enhanced rate performance. A pristine Ni 3 P films was researched as a
