Engineering green and sustainable solvents for scalable wet synthesis of sulfide electrolytes in high-energy-density all-solid-state batteries

Abstract

Argyrodites, Li6PS5Cl (LPSCl), are considered one of the most promising solid electrolytes (SEs) for all-solid-state batteries (ASSBs). However, the use of petrochemical-based toxic solvents, such as dimethylformamide and tetrahydrofuran (THF),...

Infiltration -driven performance enhancement of poly-crystalline cathodes in all-solid-state batteries

“…Furthermore, numerous papers have been published on solid electrolytes (SEs), which are essential components of all ASSBs. Among the different types of SEs developed to date, such as oxides, polymers, sulfides, and halides, sulfide SEs are particularly promising owing to their high ionic conductivity and excellent ductility [17][18][19][20][21][22] . Several sulfide SEs show high conductivities; for example, Li7P3S11 [23] , Li10GeP2S12 [24] , Li9.54Si1.74P1.44S11.7Cl0.8 [25] , and Li5.5PS4.5Cl1.5 show conductivities of 1.2×10 −2 , 1.2×10 −2 , 2.5 × 10 −2 , and 9.4 × 10 −3 S cm −1 , respectively, at 25 ℃ [26][27][28][29][30] .…”

Guanidine functionalized porous SiO2 as heterogeneous catalysts for microwave depolymerization of PET and PLA

“…The method involves reacting PET, excess diol, usually ethylene glycol (EG) and a catalyst, with the product bis(2-hydroxyethyl) terephthalate (BHET) being obtained. Many catalysts are effective for this transformation such as metal oxides, 5,6 nanoparticles, [7][8][9] metal salts and metal-containing ionic liquids, 5,10,11 and organocatalysts. [12][13][14][15][16][17][18] Metal-free catalysts are especially appealing due to their environmentally friendly and sustainable nature, serving as an advantageous option compared to metal-based catalysts.…”

Co-Al-CO3 layered double hydroxide: an efficient and regenerable catalyst for glycolysis of polyethylene terephthalate

“…3 PET glycolysis is a slow process in the absence of a catalyst and oen results in partially glycolyzed products instead of BHET. Catalysts reported for PET glycolysis can be categorized into metal derivatives, [6][7][8][9][10][11][12][13][14][15][16] ionic liquid (IL) based, [17][18][19] deep eutectic solvent (DES) [20][21][22][23][24] and organic catalysts. [25][26][27][28][29][30] Metal-based catalysts include metal salts, 31,32 metal oxides, 8,[33][34][35][36] metal-organic frameworks (MOFs), 37 metal nanoparticles, 6,[14][15][16]38 metal oxide doped graphene 11,39 , CNTs 40 and layered double hydroxides (LDHs).…”

“…100% BHET yield is reported for (h-BNNS) decorated with Fe 3 O 4 nanoparticles at 200 °C in an autoclave when reacted for 5 h. 7 100% BHET gain was also achieved by g-Fe 2 O 3 /N-doped graphene at 190 °C and 1.1 bar pressure. 46 Magnetic Fe 3 O 4 nanoparticles prepared by co-precipitation 14 are the latest additions to this group and the authors have reported a BHET yield of 93% at 195 °C for 2 h. High BHET yields are reported for most nanocatalysts, but high reaction temperature and pressure, and complex synthesis methods are drawbacks for most of them.…”
