“…Similar high Mg/Al ratios in the conditioned MACC electrolyte could be directly obtained by an interesting method involving the catalytic dissolution of Mg into THF through the addition of a small amount of CrCl 3 . Consequently, the conditioning process is unnecessary.…”

Rechargeable batteries are considered one of the most effective energy storage technologies to bridge the production and consumption of renewable energy. The further development of rechargeable batteries with characteristics such as high energy density, low cost, safety, and a long cycle life is required to meet the ever‐increasing energy‐storage demands. This Review highlights the progress achieved with halide‐based materials in rechargeable batteries, including the use of halide electrodes, bulk and/or surface halogen‐doping of electrodes, electrolyte design, and additives that enable fast ion shuttling and stable electrode/electrolyte interfaces, as well as realization of new battery chemistry. Battery chemistry based on monovalent cation, multivalent cation, anion, and dual‐ion transfer is covered. This Review aims to promote the understanding of halide‐based materials to stimulate further research and development in the area of high‐performance rechargeable batteries. It also offers a perspective on the exploration of new materials and systems for electrochemical energy storage.

“…The result indicates that the observed additional onset potential and the overpotential on other working electrodes are attributed to the heterogeneous junction of the Mg metal and the applied working electrodes. Oh et al 18 As the reaction temperatures of MMAC-DME and MMAC-DGM were higher than that of MMAC-THF, there were more Al 3+ ions being replaced in DME and DGM than in THF.…”

“…[1][2][3][4] Particularly, inorganic Mg electrolytes are very scarce. [14][15][16][17][18][19] In previous studies, the MgCl 2 /AlCl 3 electrolytes (called Magnesium and Aluminum Chloride Complex electrolytes, abbreviated as MACC electrolytes), represent the first generation of all inorganic Mg 2+ electrolytes and their simplicity is highly attractive for rechargeable Mg battery applications. 14,15 The MACC electrolytes exhibited good reversibility of Mg deposition/stripping (up to 100% Coulombic efficiency), high anodic stability (up to 3.4 V vs Mg), and limited nucleophilic susceptibility (non-nucleophilic and sulfur compatible).…”

Because of the high reactivity and sensitivity of Mg 2+ electrolytes in organic solvents, developing facile methods of preparing high-performance Mg 2+ electrolytes is still challenging and thus impedes the development of Mg batteries. In this study, a convenient method involving tertiary reactants, Mg powder, MgCl 2 , and AlCl 3 , was reported to prepare all-inorganic Mg 2+ electrolytes (termed MMAC electrolytes) in ethereal solvents. These MMAC electrolytes exhibited unprecedented performance for reversible Mg deposition, Coulombic efficiencies at 90−100%, overpotential of 125−215 mV, and anodic stability up to 3.5−3.8 V (vs Mg). A comprehensive fundamental study of the MMAC electrolytes showed that the electron transfer and mass transport kinetics during Mg deposition and stripping were affected by solvent, working electrode, and the composition of the electrolytes. In brief, these tertiary MMAC electrolytes represent the most facile and reliable inorganic Mg electrolytes known to date.

“…Ein ähnlich hohes Mg:Al‐Verhältnis in dem konditionierten MACC‐Elektrolyten konnte direkt durch Ausführung einer interessanten Methode erreicht werden, welche die katalytische Auflösung von Mg in THF durch die Zugabe einer kleinen Menge von CrCl 3 beinhaltet . Folglich ist dann der Konditionierungsprozess nicht notwendig.…”

Wiederaufladbare Batterien gelten als eine der effektivsten Energiespeichertechnologien, die die Überleitung zwischen der Erzeugung und dem Verbrauch erneuerbarer Energien schafft. Die weitergehende Entwicklung wiederaufladbarer Batterien mit Eigenschaften wie hohe Energiedichte, Kostengünstigkeit, Sicherheit und eine lange Lebensdauer muss dabei die stetig zunehmenden Energiespeicheranforderungen erfüllen. Dieser Aufsatz zeigt den wissenschaftlichen und technologischen Fortschritt wiederaufladbarer Batterien auf, der durch Halogenid‐basierten Materialien und Chemikalien zustande kommt, inklusive der Verwendung von Halogenid‐Elektroden, Halogendotierung von Elektroden und/oder Elektrodenoberflächen, Elektrolyt‐Design und Additive, die schnellen Ionen‐Shuttle und stabile Elektroden/Elektrolyt‐Grenzflächen ermöglichen sowie neue Batteriechemie realisieren. Eine Vielzahl von Batteriechemie basierend auf monovalentem Kation‐, multivalenten Kation‐, Anion‐ oder Dual‐Ionen‐Transfer wird beschrieben. Dieser Aufsatz zielt darauf ab, das Verständis von Halogenid‐basierten Materialien und Chemikalien zu fördern und die weitere Forschung und Entwicklung im Bereich hochleistungsfähiger wiederaufladbarer Batterien anzuregen. Er soll außerdem einen Ausblick auf die Nutzung neuer elektrochemischer Energiespeichermaterialien und ‐systeme bieten.
