metallanoden

Metallanoden is a term used in electrochemistry to denote metallic anodes used in energy storage and conversion devices. The term is not uniformly defined and is often used as a generic descriptor for electrode materials composed primarily of metallic elements, as opposed to intercalation or conversion-type anodes.

Origins and usage: The word is derived from metall- (metal) and Anoden (anodes). In English-language sources, metallanoden is encountered mainly in discussions of metallic or bare metal anodes and their properties, safety, and performance in batteries. The term can appear in theoretical texts, reviews, and some experimental reports, but it does not represent a fixed standard category.

Common compositions and scope: Metallanoden covers a range of metals and alloys used as anodes, including lithium metal, sodium metal, zinc, aluminum, and magnesium, as well as various alloys or composites designed to improve stability and reduce side reactions. The concept encompasses both pure metal anodes and alloy-based or coated anodes employed in rechargeable cells.

Applications and challenges: Metallanoden are central to the development of high-energy-density batteries, such as lithium metal and zinc-based systems. Their advantages include high theoretical capacity and low electrochemical potential. Major challenges involve dendrite growth, formation of solid-electrolyte interphases, volume changes during cycling, and safety concerns, driving research into electrolytes, protective coatings, and cell design.
