A LaCl3-based lithium superionic conductor compatible with lithium metal

Halide solid-state electrolytes for all-solid-state batteries: structural design, synthesis, environmental stability, interface optimization and challenges

“…1). 17–21 Firstly, the weaker Coulomb force between halogen anions and Li ions and the wider Li ion transport channel formed by relatively larger radius halogen anions (Cl − = 167 pm, Br − = 182 pm, I − = 202 pm, O 2− = 126 pm and S 2− = 170 pm) 22,23 are conducive to ion mobility and guarantee the high ionic conductivity of halide SSEs ( e.g. , Li 3 ScCl 6 , 24 3.02 mS cm −1 ).…”

Steady cycling of lithium metal anode enabled by alloying Sn-modified carbon nanofibers

“…To regulate Li deposition behavior, considerable effort has been devoted to overcoming the fragile SEI by optimizing the electrolyte formulation 23–26 or developing solid-state electrolytes. 27,28 Essentially, the uncontrollable dendritic Li growth is a typical metal electrodeposition process, and the large volume expansion of Li metal under high rates and high capacities has not yet been fully resolved. 29,30 As an alternative approach, three-dimensional (3D) hosts with large specific surface area are effective for storing Li owing to their validity in diminishing the local current density and buffering the volume change according to the Sand's model.…”

A prototype of dual-ion conductor for all-solid-state lithium batteries

“…The current Li-ion batteries based on liquid organic electrolyte always suffer from the energy density limitation and safety issues (5)(6)(7)(8). All-solid-state batteries (ASSBs) are pinned on high hopes for next-generation power batteries (9)(10)(11)(12)(13), where sulfide electrolytes represent soft mechanical properties and decent ionic conductivity [~1 mS/cm at room temperature (RT)] ( [14][15][16][17].…”
