“…also demonstrated, for the first time, the feasibility of Li 3 OCl as a solid electrolyte in a real battery, that is a full thin‐film LIB with a LiCoO 2 cathode and a graphite anode. Li 3 OCl was further developed as an effective additive in the Li 6.75 La 3 Zr 1.75 Ta 0.25 O 12 ‐based (LLZTO) garnet‐type electrolyte . Its use promoted the formation of a continuous ionic conductive network in the electrolyte and a stable lithium metal/electrolyte interface.…”

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.

Solid-state batteries hold great promise because of their safety and high projected energy density. However, the sizeable interfacial resistance between the electrodes and the electrolyte of such batteries is a significant bottleneck in the development of this technology. In this work, we develop a Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) and polyvinylidene fluoride (PVDF) solid-state composite membrane characterized by high conductivity, tensile strength, and flexibility as well as low impedance if interfacially modified by a minute amount of liquid electrolyte. A solid-state lithium-ion battery using this electrolyte with LiFePO 4 and Li as electrodes delivers excellent rate capability and cycling stability at room temperature. In particular, the battery shows an initial discharge capacity of 155 mAh g À1 and, after 100 cycles at 1C, of 145 mAh g À1 . Even at 4C, the discharge capacity is 96 mAh g À1 . Our study suggests that the interfacially modified LLZTO-PVDF membrane is a promising electrolyte for solid-state lithium-ion batteries.

“…demonstrierten auch zum ersten Mal die Anwendbarkeit von Li 3 OCl als fester Elektrolyt in einer realen Batterie der vollständigen Dünnfilm‐LIBs mit einer LiCoO 2 ‐Kathode und einer Graphit‐Anode. Das Li 3 OCl wurde im Weiteren als effektiver Zusatz im Li 6.75 La 3 Zr 1.75 Ta 0.25 O 12 ‐basierten (LLZTO) Elektrolyten vom Granat‐Typ eingesetzt . Die Anwendung trieb die Bildung eines kontinuierlichen, ionisch leitfähigen Netzwerks im Elektrolyten sowie einer stabilen Grenzfläche zwischen Lithium‐Metall und Elektrolyten voran.…”

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.
