Revealing the Structural Stability and Na-Ion Mobility of 3D Superionic Conductor Na3SbS4 at Extremely Low Temperatures

Abstract: All-solid-state batteries that employ superionic solid conductor potentially enable the broadening of battery operation in harsh environments, such as under subzero temperatures and even lower. The solid electrolyte as the key component requires structural stability, high-efficiency of ion transportation channels, and low activation energy to maintain the fast-ionic conduction against temperature drop. Herein, we use 3D superionic conductor Na 3 SbS 4 as a model to investigate the structure and conductive mech… Show more

“…Ma et al employed aqueous-based sol-gelm ethod to prepare large batch LATP (Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 )s olid electrolytes (up to 1kg) with high purity,g reat ionic conductivity (6.9 10 À4 Scm À1 ), and high density (95 %). Kotobuki and Koishic ompared the LATP (Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 )s olid electrolytes by using Al(NO 3 ) 3 and Al(C 2 H 7 O) 3 (both water soluble) as Al sources, and found that AlPO 4 impurity was observed only in the sample produced from Al(NO 3 ) 3 and not from Al(C 2 H 7 O) 3 because of lower solubility in water. [72,73] To obtain pure phase and high ion conduction, these synthetic parameters (precursors, solvents, and temperatures) need to be well controlled.…”
