Rapid Solid‐State Gas Sensing Realized via Fast K+ Transport Kinetics in Earth Abundant Rock‐Silicates

“…A computational study on the Na þ conductivity of Na 3 PS 4 also predicted the positive effect of enhanced charge carrier density in non-layered structures by substantially improving ionic conductivity. [23] K 2þx Mg 1Àx/2 SiO 4 ionic conductivity values in this study are among the highest reported in the literature compared to several similar polycrystal K-ISICs, especially at low temperatures [7,10,13,[17][18][19][20][21][24][25][26][27][28][29][30][31][32] (Figure 1b, Table S4, Supporting Information). These conductivity levels were achieved using a chemical compound without non-abundant elements, such as Sb or Te, or metals with multiple ionization states, such as Fe.…”

Advancements in cathode materials for potassium-ion batteries: current landscape, obstacles, and prospects

“…439 Despite the existence of polymer electrolytes exhibiting high K + conductivity, the literature on solid-state potassium-ion conductors remains relatively scarce. 443–476 As a result, the current focus of research revolves around enhancing the ionic conductivity of solid-state potassium-ion conductors. However, it is essential to note that other pivotal electrochemical properties often remain insufficiently characterised, including electrochemical stability, ion selectivity, mechanical properties, and assembly techniques.…”

Mechanochemical Synthesis and Characterization of K2+xZr1–xYxCl6: Potassium-Ion-Conducting Chloride

“…Solid electrolytes are required to have high ionic conductivity, chemical stability, and formability. Most of the reported K-ion conductors are based on oxides, − some of which, including K-β″-alumina and K 2 Fe 4 O 7 , , have high conductivities in excess of 10 –2 S cm –1 at room temperature. However, they have poor formability and require the preparation of single crystals or high-temperature sintered bodies to decrease grain boundary resistance.…”
