Résumé
In the context of the energy transition and the growing demand for electrochemical energy storage, the development of efficient and sustainable battery materials is a major scientific and technological challenge. Chalcogenide-based materials, including sulfides, selenides, and tellurides, have attracted increasing attention due to their versatile structural and electronic properties. This article provides a concise overview of the role of chalcogenides in battery technologies, from their historical contribution to the emergence of lithium-ion batteries to their current applications as intercalation and conversion electrodes, nanostructured negative electrodes, solid electrolytes, and lithium-rich positive electrodes in solid-state batteries. Particular emphasis is placed on the relationships between composition, structure, electrochemical mechanisms, and performance. Finally, the potential of chalcogenide materials for post-lithium battery technologies, such as sodium-, potassium-, and magnesium-ion systems, is discussed, highlighting remaining challenges and future research perspectives.
