Portable electronic devices (PEDs) are promising information‐exchange platforms for real‐time responses. Their performance is becoming more and more sensitive to energy consumption. Rechargeable batteries are the primary energy source of PEDs and hold the key to guarantee their desired performance stability. With the remarkable progress in battery technologies, multifunctional PEDs have constantly been emerging to meet the requests of our daily life conveniently. The ongoing surge in demand for high‐performance PEDs inspires the relentless pursuit of even more powerful rechargeable battery systems in turn. In this review, we present how battery technologies contribute to the fast rise of PEDs in the last decades. First, a comprehensive overview of historical advances in PEDs is outlined. Next, four types of representative rechargeable batteries and their impacts on the practical development of PEDs are described comprehensively. The development trends toward a new generation of batteries and the future research focuses are also presented.

“…Der Austausch der Fluorosubstituenten in [BF 4 ] − durch Perfluoroalkylgruppen führt hierbei zu verbesserten Eigenschaften, insbesondere zu einer höheren Ionenleitfähigkeit der entsprechenden Li + ‐Salze in Lösung. So wurde Li[C 2 F 5 BF 3 ] im Detail untersucht (Li FAB , Abbildung ), und auch für Li[B(CF 3 ) 4 ] wurden vielversprechende Ergebnisse erhalten (Abbildung ) . Die Ursache für die gesteigerte Ionenleitfähigkeit von Li[C 2 F 5 BF 3 ] und Li[B(CF 3 ) 4 ] im Vergleich zu Li[BF 4 ] liegt in der schwächeren Wechselwirkung zwischen dem Li + ‐Kation und dem Boratanionen begründet.…”

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.

Complex hydrides have attracted significant attention as better inorganic solid‐state electrolytes owing to their lightweight and good compatibility with metal anodes (Li, Na, and/or Mg) for all solid‐state batteries. However, high ionic conductivity is usually observed at high temperatures upon the stabilization of adequate crystalline phases enabling fast ionic mobility. Here, an extremely simple strategy to significantly increase the ionic conductivity of complex borohydrides is reported. By exposing complex borohydrides to oxygen, the rearrangement of surface atoms upon the oxidation of borohydride particles and the resulting defects lead to extremely high ionic conductivity. NaBH4 and LiBH4 exposed to 5% O2 show an ionic conductivity of ≈10−3 S cm−1 at 35 °C. Similarly, oxidized Mg(BH4)2 displays a conductivity of ≈10−6 S cm−1 at 25 °C instead of 9.63 × 10−13 S cm−1. To the best of the authors' knowledge, this is to date, the simplest approach to tune the properties of borohydrides toward high ionic conductivity at room temperature as it does not rely on the difficult synthesis of large cage boron based anions to substitute BH4− and allow better ionic conduction paths. Owing its simplicity, the finding has the potential to enable new avenues toward the realization of viable complex borohydride based solid‐state electrolytes.
