Broad temperature dependence, high conductivity, and structure-property relations of cold sintering of LLZO-based composite electrolytes

Controllable Li3PS4–Li4SnS4 solid electrolytes with affordable conductor and high conductivity for solid‐state battery

“…The main frame structure provides channels for ion migration along the c direction, and Li + alternately moves through Li(1) and Li(3) sites (Figure 5B), leading to the rapid ions diffusion. 6,19,23 In addition to the effect of structure control on electrical conductivity, the nature of the chemical environment around Li ions also influences its migration. Krauskopf and coworkers 26,27 proposed an idea for solid electrolyte inductive impact, in which the bonding changes of the host frame in solid electrolyte modified the potential energy pattern of the mobile ions.…”

Ceramic materials for energy conversion and storage: A perspective

“…3 for lithium aluminum titanium phosphate (LATP) electrolyte, it is possible to densify ceramics at much reduced temperatures compared to free sintering. They might for instance bring solutions to the current challenge of co-sintering mixed cathode for solid-state batteries [16,17].…”

“…They might, for instance, bring solutions to the current challenge of co-sintering mixed cathode for solid-state batteries. 16,17 Still, stringent efforts are required to transfer the accumulated laboratory-scale experience to industrial mass production, but by choosing interesting business cases, new sintering technologies can make their way toward commercialization. Looking back at the development of field-assisted sintering technology/spark plasma sintering over the last years, both diversified product range and automatization have enabled to make use of such innovation.…”

Spray Flame Synthesis (SFS) of Lithium Lanthanum Zirconate (LLZO) Solid Electrolyte

“…In addition, solid composite electrolytes (SCE) show the possibility to act as a physical separator, reducing the risk of Li dendrite growth [9] and eliminating the need for a mechanical separator used in conventional cells. Inorganic SEs such as garnet type Li 7 La 3 Zr 2 O 12 (LLZO) exhibit a number of advantageous properties, such as negligible electronic conductivity, high temperature battery performance, large electrochemical stability window, acceptable Li conductivity (~1 mS cm −1 ), and high elastic modulus [10][11][12][13][14]. These properties make LLZO as a one of the most promising SCE that can meet the commercialization criteria [15].…”
