“…In the aforementioned studies, given the use of borohydrides, the true oxidative stabilities of these solutions were low (<2.5 V). Therefore, to eliminate challenges associated with the use of strongly reducing agents, a new recent alternate approach designed, for the first time, ionic liquids based on closo-borates for Mg batteries [108]. This was inspired from the high compatibility of the carborate anion as was revealed from the Mg salts analogues (Section 4).…”

The ever-rising demands for energy dense electrochemical storage systems have been driving interests in beyond Li-ion batteries such as those based on lithium and magnesium metals. These high energy density batteries suffer from several challenges, several of which stem from the flammability/volatility of the electrolytes and/or instability of the electrolytes with either the negative, positive electrode or both. Recently, hydride-based electrolytes have been paving the way towards overcoming these issues. Namely, highly performing solid-state electrolytes have been reported and several key challenges in multivalent batteries were overcome. In this review, the classes of hydride-based electrolytes reported for energy dense batteries are discussed. Future perspectives are presented to guide research directions in this field.

Direkt an der Grenze zwischen Metallen und Nichtmetallen angesiedelt, nimmt das Element Bor eine einzigartige Position im Periodensystem ein. Diese besondere Stellung ermöglicht eine enorme Vielfalt an chemischen Reaktionen und Anwendungen. Auch in Hinblick auf die stetig steigende Nachfrage an erneuerbaren und sauberen Energien bzw. energieeffizienten Prozessen ist das Element Bor mehr und mehr in den Fokus der energiebezogenen Forschung gerückt und umfasst mittlerweile Bereiche wie 1) die Aktivierung und Synthese kleiner energiereicher Moleküle, 2) die Speicherung von chemischer und elektrischer Energie und 3) die Umwandlung von elektrischer Energie zu Licht. Diese Anwendungen basieren hierbei auf den besonderen Eigenschaften des Elements Bor, d. h. vor allem auf dessen Elektronenmangel in Verbindung mit der Gegenwart eines unbesetzten p‐Orbitals, was die Ausbildung unzähliger Verbindungen mit gezielt beeinflussbaren chemischen und physikalischen Eigenschaften ermöglicht. So erreicht Bor beispielsweise mit vier kovalenten Bindungen und einer negativen Ladung relativ einfach ein Elektronenoktett, wodurch die Verbindungsklasse der Boratanionen zugänglich wird, welche eine außergewöhnlich hohe chemische und elektrochemische Stabilität aufweisen. Besonders hervorzuheben ist in diesem Zusammenhang die synthetisch wertvolle Klasse der schwach‐koordinierenden Anionen. Dieser Aufsatz soll die Bedeutung von Borverbindungen für energiebezogene Prozesse und Anwendungen verdeutlichen und fasst die Fortschritte der letzten Jahre auf diesem Gebiet zusammen.
