TL;DR: The opportunities for designing new electrolytes appear to be almost infinite, which certainly complicates strict classification of such systems and a fundamental understanding of their properties, but these innumerable opportunities also provide a great chance of developing highly functionalized, new electrolyte systems, which may overcome the afore-mentioned safety concerns.

TL;DR: In this article, the recent progress and remaining challenges of conversion reactions for Li-ion batteries and SIBs are discussed, covering an overview about the different synthesis methods, morphological characteristics, as well as their electrochemical performance.

TL;DR: It is shown here that consistent progress has been achieved, to the point that this battery is now considered to be near to industrial production, however, the performance of present lithium-sulfur batteries is still far from meeting their real energy density potentiality.

TL;DR: In this article, the authors provide an overview on the relevant fundamental aspects for the de-/lithiation mechanism, the already overcome and remaining challenges (including, for instance, the potential fast charging and the recycling), as well as recent progress in the field such as the tradeoff between relatively cheaper natural graphite and comparably purer synthetic graphite, and the introduction of relevant amounts of silicon (oxide) to boost the energy and power density.

TL;DR: This review aims at providing a comprehensive overview of the up-to-date known structural models of hard carbons and their correlation with the proposed models for the sodium-ion storage mechanisms and a careful evaluation of potential strategies to ensure a high degree of sustainability.
