This mini-review describes the thermal in situ generation of N-heterocyclic carbenes (NHCs) from various heat sensitive precursors for use in organocatalysis and in polymer chemistry. Thermally labile progenitors such as azolium hydrogen carbonates, NHC-CO2 adducts, alcohol-protected NHCs and NHC-metal complexes are discussed and compared in their scope and limitations. Advantageous aspects like enhanced stability, controlled release by external stimuli, latency and co-catalysis by the protecting groups are illuminated in numerous examples, stressing the versatility and adaptability that can be achieved by protected NHCs. Emerging strategies to harness the reactivity of NHCs are also briefly discussed to provide an outlook on where future developments are to be expected.

Inspired by the first rechargeable Mg battery about 20 years ago, based on a Chevrel phase cathode, a Mg foil anode, and a magnesium organo‐aluminate electrolyte, research on rechargeable batteries using sulfur as the cathode together with Mg as the anode has gained substantial and increasing interest. In particular, the safety characteristics of magnesium–sulfur (Mg–S) batteries, the high abundance of both magnesium and sulfur, and the high theoretical volumetric energy density of magnesium render this system specifically interesting for mobile applications that require high volumetric energy densities, i.e., the automotive and aviation sector. While the development of Mg–S batteries is still at a nascent stage, some breakthroughs have already been accomplished. Consequently, it appears necessary to provide a comprehensive up‐to‐date review about the current achievements to facilitate further improvements in this field. In this review, the state of the art in Mg–S batteries is summarized, focusing on sulfur conversion cathodes, magnesium anode materials, currently employed electrolyte systems, as well as on current collectors and separator design. In addition, the challenges and some possible future work to realize a practically applicable and technically viable Mg–S battery are highlighted.

A fundamental analytical and electrochemical study on various sulfur-poly(acrylonitrile) (SPAN) composites for Li–S batteries synthesized at various temperatures is presented. According to elemental analysis and X-ray photoelectron spectroscopy (XPS), the sulfur content in SPAN composites decreases with increasing synthesis temperature. However, as shown by RAMAN spectroscopy, higher synthesis temperatures result in higher degrees of graphitization of the polymer backbone and eventually in higher C-rate capabilities and higher cycle stability. The latter is also supported by the larger specific surface area of the SPAN composite prepared at higher temperature. However, complementary thermogravimetry-mass spectroscopy (TG-MS) measurements show a degradation of the composite prepared at temperatures >450 °C, rendering 390–460 °C the optimum temperature range for synthesis. Finally, the C-rate capability increases with decreasing thickness of the cathode, resulting in a 95% relative specific capacity at 1C compared to C/10.
