Advanced superionic conductor

An advanced superionic conductor (AdSIC) in materials science, is a fast-ion conductor that has a crystal structure close to optimal for fast-ion transport (FIT).

History

The term was introduced in a paper by A.L. Despotuli, A.V. Andreeva and B. Rambaby.^[1]

Characteristics

The rigid ion sublattice of Advanced SuperIonic Conductors (AdSICs) has structure channels where mobile ions of opposite sign migrate. Their ion-transport characteristics display ionic conductivity of ~0.3/Ω cm (RbAg₄I₅, 300 K) and activation energy of E_i~0.1 eV. This determines the temperature-dependent concentration of mobile ions ni~Ni x e^Ei/kBT capable to migrate in conduction channels at each moment (Ni~10²²/cm³, ni~2x10²⁰/cm³, 300 K).

The Rubidium silver iodide–family is a group of AdSIC compounds and solid solutions that are isostructural with the RbAg₄I₅ alpha modification. Examples of such compounds with mobile Ag⁺- and Cu⁺-cations include KAg₄I₅, NH₄Ag₄I₅, K_1−xCs_xAg₄I₅, Rb_1−xCs_xAg₄I₅, CsAg₄Br_1−xI_2+x, CsAg₄ClBr₂I₂, CsAg₄Cl₃I₂, RbCu₄Cl₃I₂ and KCu₄I_5.^[2]^[3]^[4]^[5]^[6]^[7]

RbAg₄I₅ AdSIC displays peculiar features of crystal structure and dynamics of mobile ions.^[8]^[9]^[10]

Recently, all solid state micrometre-sized supercapacitors based on AdSICs (nanoionic supercapacitors) had been recognized as critical electron component of future sub-voltage and deep-sub-voltage nanoelectronics and related technologies (22 nm technological node of CMOS and beyond).^[11] Researchers also developed an all-solid-state battery employing RbAg₄I₅ superionic conductor.^[12]
