“…Of particular interest is that the VB-sulfur vulcanized battery used in Figure b was still active; therefore, it was evaluated in succession for an additional 250 cycles at a faster rate of 0.3 C rate to determine cyclic stability. , Figure a shows the charging and discharging profiles acquired every 50 cycles. The voltage was scanned between 1.7 and 2.85 V to cycle the charge and discharge processes with the current density of about 0.9 mA cm –2 .…”

Vinyl-benzaldehyde (VB) monomers containing four functional groups were newly synthesized using the Williamson ether synthesis method. The two aldehyde groups of the synthesized monomers were able to react with amine-terminated macromonomers to form flexible networks. In addition, the two vinyl groups were found to be capable of inverse vulcanization with sulfur by conducting qualitative chemical analysis. The lithium–sulfur battery prepared using the VB-based cathode binder achieved high specific capacity with excellent capacity retention compared to conventional sulfur batteries, demonstrating the potential of the new binder.

“…Unlike lithium metal systems, reversible plating/stripping of magnesium is challenging owing to its strong tendency to form insulating passivation film in most aqueous/organic solvents, salts, and contaminants, resulting in complete termination of electrochemical reaction. [55] Very encouragingly, the invention of Grignard-based organic electrolyte has broken through the bottleneck of compatibility along with tremendous trial-anderror efforts. In 1990, Gregory et al reported Grignard-based electrolytes containing Mg salts based on organoborate or organoaluminate anions.…”

Rechargeable magnesium batteries (RMBs) are promising candidates to replace currently commercialized lithium‐ion batteries (LIBs) in large‐scale energy storage applications owing to their merits of abundant resources, low cost, high theoretical volumetric capacity, etc. However, the development of RMBs is still facing great challenges including the incompatibility of the electrolyte and the lack of suitable cathode materials with high reversible capacity and fast kinetics of Mg2+. While tremendous efforts have been made to explore compatible electrolytes and appropriate electrode materials, the rational design of unconventional Mg‐based battery systems is another effective strategy for achieving high electrochemical performance. This review specifically discusses the recent research progress of various Mg‐based battery systems. First, the optimization of electrolyte and electrode materials for conventional RMBs is briefly discussed. Furthermore, various Mg‐based battery systems, including Mg‐chalcogen (S, Se, Te) batteries, Mg‐halogen (Br2, I2) batteries, hybrid‐ion batteries, and Mg‐based dual‐ion batteries are systematically summarized. This review aims to provide a comprehensive understanding of different Mg‐based battery systems, which can inspire latecomers to explore new strategies for the development of high‐performance and practically available RMBs.

“…Unfortunately, low ionic conductivity at room temperature (RT) caused by the high crystallinity of the polymer matrix impedes their application. Incorporating a liquid plasticizer into the polymer matrix to form a quasi-solid-state electrolyte 5–7 can promote the segmental motion of polymer chains, increase the dissociation of the Li salt and reduce the interface contact resistance, but this usually results in poor mechanical strength. Alternatively, introducing inorganic fillers into the SPEs 8–10 can also increase the proportion of amorphous regions to improve ionic mobility, as well as enhance the mechanical properties of the membrane; however, it is difficult to achieve the uniform distribution of the solid particles in the polymer matrix.…”
