“…Potassium adopts innumerable polyhedral coordination; 3 thus, K-based compounds have an abundance of piquant physical properties such as ferroelectricity, piezoelectricity, pyroelectricity, multiferroicity, thermoelectricity, and optics 4–13 . K-based compounds have also found their niche application in energy storage as host frameworks for reversible reinsertion of Li and Na electrodes.…”

Rechargeable potassium-ion batteries have been gaining traction as not only promising low-cost alternatives to lithium-ion technology, but also as high-voltage energy storage systems. However, their development and sustainability are plagued by the lack of suitable electrode materials capable of allowing the reversible insertion of the large potassium ions. Here, exploration of the database for potassium-based materials has led us to discover potassium ion conducting layered honeycomb frameworks. They show the capability of reversible insertion of potassium ions at high voltages (~4 V for K2Ni2TeO6) in stable ionic liquids based on potassium bis(trifluorosulfonyl) imide, and exhibit remarkable ionic conductivities e.g. ~0.01 mS cm−1 at 298 K and ~40 mS cm–1 at 573 K for K2Mg2TeO6. In addition to enlisting fast potassium ion conductors that can be utilised as solid electrolytes, these layered honeycomb frameworks deliver the highest voltages amongst layered cathodes, becoming prime candidates for the advancement of high-energy density potassium-ion batteries.

“…As found for most coordination polymers with ADC 2as bridging ligand and low valent metal ions the ADC 2anions are oriented parallel to each other ( Figure 2). The surprising structural complexity of this coordination polymer is also reflected by its Niggli formula The distances between Li + cations and coordinating oxygen atoms are in the expected range [15] [shortest: 191.9(4) pm for Li2-O2, longest: 202.0(4) pm for Li2-O5; Table 3]. Compared with the already known LiHADC·H 2 O, some of the Li-O distances in 1 are slightly elongated: 192-202 pm for 1 and 187-198 pm for LiHADC·H 2 O.…”

Single crystals of dilithium‐acetylenedicarboxylate‐dihydrate, Li2ADC·2H2O (1), were isolated from a solid product formed by isothermal evaporation of an aqueous solution of LiOH und acetylenedicarboxylic acid (H2ADC). 1 crystallizes in the triclinic space group P1 with Z = 2. LiO4 tetrahedra are interconnected by ADC2– anions and water molecules to form a 3D polymeric structure. Coupled TGA and DTA measurements show that 1 loses its two water molecules above 100 °C. Heating a polycrystalline sample of 1 at 140 °C for 2 h in an argon atmosphere leads to a significant change of the powder diffraction pattern indicating the formation of the new anhydrous coordination polymer dilithium‐acetylenedicarboxylate, Li2ADC (2). Its crystal structure was solved and refined from X‐ray powder diffraction data. 2 crystallizes in the orthorhombic space group Fddd (Z = 8). LiO4 tetrahedra are interconnected by ADC2– anions to form a 3D polymeric structure.

Laverovite (IMA 2017-009b), ideally K 2 NaMn 7 Zr 2 (Si 4 O 12 ) 2 O 2 (OH) 4 F, is a kupletskite-group (astrophyllite-supergroup) mineral from Mont Saint-Hilaire, Québec, Canada. Associated minerals are zircophyllite, kupletskite, astrophyllite, aegirine, analcime, orthoclase, and albite. Laverovite is brown, transparent in thin grains, and has a vitreous luster. Mohs hardness is 3, (5); 2V meas. ¼ 82(2)8, 2V calc. ¼ 808, strong dispersion: r . v. Cleavage is perfect parallel to {001}.
