“…For example, the LiFe 0.4 Mn 0.6 (PO 4 ) 0.09 I 0.01 cathode with a low‐iodine substitution delivered a highly stable capacity of 102 mAh g −1 at a current rate of 3 C (Figure a). In contrast, the LiFe 0.4 Mn 0.6 PO 4 cathode could hardly discharge . The reversible capacity of the MoO 3 cathode was increased from 120 to 160 mAh g −1 by fluorine substitution, which led to a charge redistribution in the crystal lattice and a significant increase of conductivity from 4.4×10 −9 to 1.8×10 −6 S cm −1 …”

“…found that electrical conductivity could be enhanced by fluorine substitution in the LiFe 0.4 Mn 0.6 PO 4− δ F δ cathode . Substitution with large halide ions (Cl − , Br − , or I − ) also increased the electrical conductivity and facilitated diffusion of the lithium ions . For example, the LiFe 0.4 Mn 0.6 (PO 4 ) 0.09 I 0.01 cathode with a low‐iodine substitution delivered a highly stable capacity of 102 mAh g −1 at a current rate of 3 C (Figure a).…”

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.

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.

A LiFe0.6Mn0.4PO4 (LFMP) cathode exploiting the olivine structure is herein synthesized and characterized in terms of structure, morphology, and electrochemical features in a lithium cell. The material shows reversibility of the electrochemical process which evolves at 3.5 and 4 V versus Li+/Li due to the Fe+2/Fe+3 and Mn+2/Mn+3 redox couples, respectively, as determined by cyclic voltammetry. The LFMP has a well‐defined olivine structure revealed by X‐ray diffraction, a morphology consisting of submicron particle aggregated into micrometric clusters as indicated by scanning and transmission electron microscopy, with a carbon weight ratio of about 4% as suggested by thermogravimetry. The electrode is used in lithium cells subjected to galvanostatic cycling with a conventional liquid electrolyte, and demonstrates a maximum capacity of 130 mAh g−1, satisfactory rate capability, excellent efficiency, and a stable trend. Therefore, the material is studied in a lithium metal polymer cell exploiting an electrolyte based on polyethylene glycol dimethyl ether with a solid configuration. The cell reveals very promising features in terms of capacity, efficiency, and retention, and suggests the LFMP material as a suitable electrode for polymer batteries characterized by increased energy density and remarkable safety.
