“…Among the solid electrolytes reported so far, several materials have shown to be promising candidates for practical application in lithium ion batteries, such as sulphide glasses [ 5 , 6 , 7 , 8 ], sulphide crystalline materials [ 9 , 10 , 11 ], garnet-type Li 7 La 3 Zr 2 O12 (LLZO) [ 12 ], NASICON-type oxides [ 5 ], or germanium-based Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (AGP) [ 4 ]. Another interesting material is the perovskite lithium lanthanum titanate (LLTO) (stoichiometry La 2/3-x Li 3x TiO 3 ), which presents higher lithium ion bulk conductivity (10 −3 S cm −1 ) compared to other oxide-type solid electrolytes [ 13 , 14 , 15 ].…”

The organic solvents that are widely used as electrolytes in lithium ion batteries present safety challenges due to their volatile and flammable nature. The replacement of liquid organic electrolytes by non-volatile and intrinsically safe ceramic solid electrolytes is an effective approach to address the safety issue. However, the high total resistance (bulk and grain boundary) of such compounds, especially at low temperatures, makes those solid electrolyte systems unpractical for many applications where high power and low temperature performance are required. The addition of small quantities of a polymer is an efficient and low cost approach to reduce the grain boundary resistance of inorganic solid electrolytes. Therefore, in this work, we study the ionic conductivity of different composites based on non-sintered lithium lanthanum titanium oxide (La0.5Li0.5TiO3) as inorganic ceramic material and organic polymers with different characteristics, added in low percentage (<15 wt.%). The proposed cheap composite solid electrolytes double the ionic conductivity of the less cost-effective sintered La0.5Li0.5TiO3.

“…Substituting an inorganic (superionic) solid electrolyte for the liquid electrolyte in LIBs is a potentially viable strategy to increase energy density and minimize safety risks due to cell failure [4][5][6] . Lithium thiophosphates, such as argyrodite Li 6 PS 5 Cl, are among the most promising solid electrolytes because of their high ionic conductivity at room temperature and favorable ductility properties [7][8][9][10][11][12][13][14][15][16][17] . At the positive electrode side, Ni-rich layered lithium metal oxides, such as LiNi 1-x-y Co x Mn y O 2 (NCM or NMC) or LiNi 1-x-z Co x Al z O 2 (NCA) with ≥ 0.6 Ni content, are regarded generally as state-of-the-art cathode materials for bulk solid-state battery (SSB) applications [18][19][20][21] , as in the case of energy-dense LIBs.…”

While still premature as an energy storage technology, bulk solid-state batteries are attracting much attention in the academic and industrial communities lately. In particular, layered lithium metal oxides and lithium thiophosphates hold promise as cathode materials and superionic solid electrolytes, respectively. However, interfacial side reactions between the individual components during battery operation usually result in accelerated performance degradation. Hence, effective surface coatings are required to mitigate or ideally prevent detrimental reactions from occurring and having an impact on the cyclability. In the present work, we examine how surface carbonates incorporated into the sol–gel-derived LiNbO3 protective coating on NCM622 [Li1+x(Ni0.6Co0.2Mn0.2)1–xO2] cathode material affect the efficiency and rate capability of pellet-stack solid-state battery cells with β-Li3PS4 or argyrodite Li6PS5Cl solid electrolyte and a Li4Ti5O12 anode. Our research data indicate that a hybrid coating may in fact be beneficial to the kinetics and the cycling performance strongly depends on the solid electrolyte used.

“…In contrast, sulfide-based solid electrolytes such as Li 2 S-P 2 S 5 (LPS)-based glass or glass ceramics and Li 6 PS 5 X (X = Cl, Br, I) with an argyrodite crystal structure are superionic conductors with high electrochemical stability and ionic conductivity [10]. Owing to their negligible grain-boundary resistance, sulfide-based electrolytes exhibit excellent conductivity even under cold-pressing conditions.…”

Li6.3La3Zr1.65W0.35O12 (LLZO)-Li6PS5Cl (LPSC) composite electrolytes and all-solid-state cells containing LLZO-LPSC were fabricated by cold pressing at room temperature. The LPSC:LLZO ratio was varied, and the microstructure, ionic conductivity, and electrochemical performance of the corresponding composite electrolytes were investigated; the ionic conductivity of the composite electrolytes was three or four orders of magnitude higher than that of LLZO. The high conductivity of the composite electrolytes was attributed to the enhanced relative density and the rule of mixture for soft LPSC particles with high lithium-ion conductivity (~10−4 S·cm−1). The specific capacities of all-solid-state cells (ASSCs) consisting of a LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode and the composite electrolytes of LLZO:LPSC = 7:3 and 6:4 were 163 and 167 mAh·g−1, respectively, at 0.1 C and room temperature. Moreover, the charge–discharge curves of the ASSCs with the composite electrolytes revealed that a good interfacial contact was successfully formed between the NCM811 cathode and the LLZO-LPSC composite electrolyte.
