Electrolyüdide

Electrolyüdide is a term used in speculative chemistry to denote a class of ionic compounds proposed for use in high ionic conductivity electrolytes. The name blends electrolyte with the suffix -ide, signaling a salt-like species whose anionic component is highly delocalized. In theoretical models, Electrolyüdide consists of a bulky cation—often organic or organometallic—paired with a delocalized anionic polyhalide or polyiodide framework. The resulting lattice is envisioned to support rapid ionic transport while minimizing electronic conduction.

Structural predictions suggest layered or framework-type crystal motifs with diffusion channels that accommodate easy movement of cations. The polyiodide-rich anion is highly polarizable, which is thought to facilitate ion hopping and suppress short-range order that would impede transport. Predicted properties include high ionic conductivity at or near room temperature, a wide electrochemical stability window, and low electronic conductivity, all desirable for solid-state electrolyte applications. Thermal stability is typically emphasized in theoretical assessments.

Synthesis in practical terms has not been demonstrated in widely cited experiments; in theory, preparation would involve metathesis reactions between bulky organic salts and polyiodide sources under inert conditions, followed by crystallization or film formation. Given its hypothetical status, concrete safety, environmental, and scalability data are not established.

Potential applications of Electrolyüdide concepts lie in solid-state batteries, electrochromic devices, and other electrochemical systems requiring safe, high-conductivity electrolytes. The term remains primarily of interest in exploratory and theoretical discussions of ion-conducting materials.
