Earth-abundant metal anodes have become one of the hottest topics in recent years. As alternatives to lithium metals, earth-abundant metal anodes have significantly lower cost and higher energy density, but with unprecedented problems that cannot be solved by simply referring to experiences with lithium-metal anodes. The electrolytes for these anodes greatly influence the overall performance, such as Coulombic efficiency, stability, and even the availability to become an anode. In this Minireview, some excellent state-of-art works on the electrolytes of energy-storage systems with sodium-, potassium-, magnesium-, calcium-, and aluminum-metal anodes are concisely summarized. The performance of these systems is highlighted by the rational design of the electrolyte and electrolyte/electrode interface.

“…[17,18,[20][21][22][23]26] An Al battery that is comprised of three-dimensional graphitic-foamc athode graphite has attracted globala ttention owing to its ultrafast charging rate and the involvement of intercalation/deintercalation of AlCl 4 anions during charging/discharging, respectively. [29][30][31][32] However,m any experimental studies on anion intercalation and the theoretical study we conducted on graphite electrodeh ave shown that the very first intercalation step (cycle) differs from the other successive steps because it involves the activation of partially closed interlayer spaceso f graphite layers during the initial intercalation of the anion, which results in lower discharge capacities.

Exploring suitable electrode materials is a fundamental step toward developing Al batteries with enhanced performance. In this work, we explore using density functional theory calculations the feasibility of single-walled carbon nanotubes (SWNTs) as a cathode material for Al batteries. Carbon nanotubes with hollow structures and large surface area are able to overcome the difficulty of activating the opening of interlayer spaces as observed in graphite electrode during the first intercalation cycle. Our results show that AlCl binds strongly with the SWNT to result in an energetically and thermally stable AlCl -adsorbed SWNT system. Diffusion calculations show that the SWNT system allows ultrafast diffusion of AlCl with a more favorable inner surface diffusion than outer surface diffusion. Our charge-density difference and Bader atomic charge analysis confirm the oxidation of SWNT upon adsorption of AlCl , which shows a similar behavior to the previously studied graphite cathode. The average open-circuit voltage and AlCl storage capacity increases with increasing SWNT diameter and can be as high as 1.96 V and 275 mA h g in (25,25) SWNT relative to graphite (70 mA h g ). All of these properties show that SWNTs are a potential cathode material for high-performance Al batteries and should be explored further.

“…Nichtwässrige Elektrolyten für diese elektrolytische Abscheidung weisen hohe Ionenleitfähigkeit, hohe Coulombsche Effizienz, schnelle elektrochemische Kinetiken und ein weites elektrochemisches Fenster auf. Aus diesen Gründen wurden sie als wichtige Kandidaten für realisierbare wiederaufladbare Aluminiumbatterien (RABs) vorgeschlagen . Die nichtwässrigen Elektrolyten, welche reversible Aluminium‐Abscheidung und ‐Stripping befähigen, können in drei Typen kategorisiert werden: 1) AlCl 3 /Chlorid‐basierte ionische Flüssigkeiten, 2) eutektische Systeme aus AlCl 3 /organischem Lösungsmittel und 3) eutektische Systeme aus anorganischem AlCl 3 /Alkalimetallchlorid.…”

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.
