Investigation of the structure and ionic conductivity of a Li3InCl6 modified by dry room annealing for solid-state Li-ion battery applications

On the Influence of Li3InCl6−PEDOT:PSS Hybrids in Solid‐State Batteries Prepared via an Aqueous One‐Pot Approach

“…Those reflections were often reported to be found in Li 3 InCl 6 halide samples obtained both via ball-milling and solution-synthesis. [18,33,42,44,58,59] They could be assigned to the presence of the hydrated Li 3 InCl 6 in very small amounts. [44,58] The TGA of the composites was also performed in open alumina crucibles for samples with different CP loadings (Figure S8).…”

“…, Li 3 Y 1− x In x Cl 6 , 38 Li 3− x Er 1− x Zr x Cl 6 . 39 From another viewpoint, halide fast Li-ion conductors can be generally divided into four categories according to crystalline structures, including (i) trigonal structures (space groups: P 3̄ m 1), such as Li 3 YCl 6 , 33 and Li 3 ErCl 6 ; 40,41 (ii) monoclinic structures (space groups: C 2/ m ), such as Li 3 YBr 6 , 33 Li 3 InCl 6 , 42 and Li 3 ScCl 6 ; 24 (iii) orthorhombic structures (space groups: Pnma ), such as Li 3 YbCl 6 43 and Li 2.5 Y 0.5 Zr 0.5 Cl 6 ; 44 (iv) spinel structures (space groups: Fd 3̄ m ), such as Li 2 Sc 2/3 Cl 4 , 45 Li 2 Sc 2/3− x Er x Cl 4 , 46 and Li 2 FeCl 4 . 47 In parallel, halide fast Na-ion conductors, mainly including Na 2 ZrCl 6 , 48 NaAlCl 4 , 49 Na 3 MCl 6 (M = Y, Er, In, Sc, and Yb), 50–52 Na 3 MBr 6 , 51,53 Na 3 MI 6 (M = Sc, Y, La, and In), 54,55 Na 3− x Y 1− x Zr x Cl 6 , 56,57 Na 3− x Er 1− x Zr x Cl 6 , 58 Na 2 In x Sc 0.666− x Cl 4 , 59 and Na 3 In 1− x Sc x Cl 6 (ref.…”

Hexavalent Ions Insertion in Garnet Li7La3Zr2O12 Toward a Low Temperature Densification Reaction

“…[5,6] Because of these safety hitches, strong efforts have been made for the development of all-solid-state Li-ion batteries (ASSLIBs), [7,8] replacing conventional graphite-based anodes and flammable electrolytes with Li-metal anodes and solid-state electrolytes. [8] Among the families of materials investigated for this purpose, we can find polymers (PEO-LiTFSI), [9] ceramics (e. g., garnets [10] , perovskites, [11] NaSICON, [12,13] sulfides [14] and halides [15,16] ) and hybrids (ceramicpolymer composites). [17,18] A good solid electrolyte should meet several requirements: a wide stability window against Li metal and high-voltage cathodes, [19,20] a high room temperature ionic conductivity (> 10 À 3 S cm À 1 ) with low electronic conductivity, [21] a good chemical and thermal stability, and good mechanical properties.…”
