“…54,55 Improving the electrochemical behaviour of the sulphur cathode can be achieved with various carbon materials with high conductivity, tunability, and porosity. 56 As such, several types of materials have been used to improve cyclic stability: functionalized carbon, 57,58 metal oxides/sulphides/ nitrides, [59][60][61] covalent-organic frameworks 62 and metal-organic frameworks, [63][64][65][66][67][68][69] all of the mentioned materials have a high affinity for polar polysulphides.…”

“…Two activated and two carbonized MOF materials were used as a host for sulphur in cathode materials for Li-S batteries. The synthesis of microporous material GaTCPP with exact chemical formula {[Ga2(H2TCPP)(OH)2]•5DMF•2H2O}n (H2TCPP = (4,4´,4´´,4´´´-(5,10,15,20-porphyrintetrayl)tetrabenzoate, DMF = N,N´-dimethylformamide) is described in [18], MOF-76(Gd) with the chemical formula {[Gd(BTC)(H2O)]•DMF}n (BTC = benzene-1,3,5-tricarboxylate) in [4,13], and MIL-101(Fe)-NH2 with chemical composition {[Fe3(O)(BDC-NH2)3(H2O)2Cl]•G}n (where BDC-NH2 = 2aminoterephthaliate, G = guest molecules) in [9]. MOFs GaTCPP and MOF-76(Gd) were applied in an activated state (AC), and MOF-76(Gd) and MIL-101(Fe)-NH2 were carbonized (C) in a tubular furnace at 700 °C in a nitrogen atmosphere.…”

“…As an alternative, the conversion mechanism of lithium-sulphur (Li-S) batteries became the target of intensive research. Li-S batteries are considered a candidate for next-generation energy storage systems thanks to their high theoretical energy density (2600 Wh kg -1 ), environmentally friendliness, and low sulphur cost [4][5][6]. However, their practical application is hampered by several issues.…”

The development of new battery systems has been intensively pursued in an effort to increase energy densities. Lithium-sulphur batteries represent a group of next-generation batteries with high theoretical capacity and energy density. The electrochemical properties of lithium-sulphur batteries may be improved by the application of appropriate conductive and porous additives to sulphur in the cathode material. Recently, materials belonging to the group of metal-organic frameworks (MOFs) have been widely investigated as host materials for sulphur thanks to their unique porous structure. In this work, various types of MOFs (GaTCPP, MOF-76(Gd), MIL-101(Fe)-NH2) were applied to the cathode material. MOFs were activated or carbonized before cathode material preparation. The structure of activated GaTCPP showed the lowest capacity fading per cycle (0.07 %) from activated MOFs during cycling at 0.5 C for 200 cycles. The carbonization process may improve the electrochemical properties of the electrode material. The best electrochemical properties showed carbonized MOF-76(Gd), and the capacity fading rate per cycle was only 0.04 % despite 200 cycles at 0.5 C.

“…The inorganic units can be metal cations or clusters; the latter is widely described as secondary building units (SBUs) with different shapes and sizes. Because of the extraordinary variability degree of building blocks, their enormous surface areas, and the multiple ways of surface functionalization and modification, MOFs have considerable potential in many application areas, such as gas storage [ 1 , 2 , 3 , 4 ] and separation [ 5 , 6 ], heterogeneous catalysis [ 7 , 8 , 9 , 10 ], drug delivery [ 11 , 12 , 13 ], water [ 14 , 15 , 16 , 17 ] and sensor technology [ 18 , 19 ], magnetic refrigeration [ 20 , 21 , 22 ], or conductive matrix for sulphur in lithium-sulphur (Li-S) batteries [ 23 , 24 , 25 , 26 ].…”

“…Lithium-sulphur (Li-S) batteries are considered as one of the most promising candidates to replace currently used lithium-ion batteries, thanks to their enormous energy density (~2600 Wh kg −1 ) and theoretical capacity (1675 mAh g −1 ) [ 45 , 46 ]. Applying AE-MOFs as supports for sulphur in Li-S batteries may suppress their shortcomings due to their unique structure and properties [ 25 , 26 , 47 , 48 , 49 ]. Indeed, during discharging of the Li-S battery, sulphur rebounds with lithium ions: the intermediate products are soluble long-chain polysulphides (Li 2 S x , 4 ≤ x ≤ 8) and the discharge products are insoluble short-chain polysulphides (Li 2 S 2 /Li 2 S) [ 50 , 51 ].…”

Two new alkaline earth metal–organic frameworks (AE-MOFs) containing Sr(II) (UPJS-15) or Ba(II) (UPJS-16) cations and extended tetrahedral linker (MTA) were synthesized and characterized in detail (UPJS stands for University of Pavol Jozef Safarik). Single-crystal X-ray analysis (SC-XRD) revealed that the materials are isostructural and, in their frameworks, one-dimensional channels are present with the size of ~11 × 10 Å2. The activation process of the compounds was studied by the combination of in situ heating infrared spectroscopy (IR), thermal analysis (TA) and in situ high-energy powder X-ray diffraction (HE-PXRD), which confirmed the stability of compounds after desolvation. The prepared compounds were investigated as adsorbents of different gases (Ar, N2, CO2, and H2). Nitrogen and argon adsorption measurements showed that UPJS-15 has SBET area of 1321 m2 g−1 (Ar) / 1250 m2 g−1 (N2), and UPJS-16 does not adsorb mentioned gases. From the environmental application, the materials were studied as CO2 adsorbents, and both compounds adsorb CO2 with a maximum capacity of 22.4 wt.% @ 0 °C; 14.7 wt.% @ 20 °C and 101 kPa for UPJS-15 and 11.5 wt.% @ 0°C; 8.4 wt.% @ 20 °C and 101 kPa for UPJS-16. According to IAST calculations, UPJS-16 shows high selectivity (50 for CO2/N2 10:90 mixture and 455 for CO2/N2 50:50 mixture) and can be applied as CO2 adsorbent from the atmosphere even at low pressures. The increased affinity of materials for CO2 was also studied by DFT modelling, which revealed that the primary adsorption sites are coordinatively unsaturated sites on metal ions, azo bonds, and phenyl rings within the MTA linker. Regarding energy storage, the materials were studied as hydrogen adsorbents, but the materials showed low H2 adsorption properties: 0.19 wt.% for UPJS-15 and 0.04 wt.% for UPJS-16 @ −196 °C and 101 kPa. The enhanced CO2/H2 selectivity could be used to scavenge carbon dioxide from hydrogen in WGS and DSR reactions. The second method of applying samples in the area of energy storage was the use of UPJS-15 as an additive in a lithium-sulfur battery. Cyclic performance at a cycling rate of 0.2 C showed an initial discharge capacity of 337 mAh g−1, which decreased smoothly to 235 mAh g−1 after 100 charge/discharge cycles.
