Rational Design of High-Performance PEO/Ceramic Composite Solid Electrolytes for Lithium Metal Batteries

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Март 31, 2023

Composite solid electrolytes (CSEs) with poly(ethylene oxide) (PEO) have become fairly prevalent for fabricating high-performance solid-state lithium metal batteries due to their high Li+ solvating capability, flexible processability and low cost. However, unsatisfactory room-temperature ionic conductivity, weak interfacial compatibility uncontrollable Li dendrite growth seriously hinder progress. Enormous efforts been devoted combining PEO ceramics either as fillers or major matrix the rational design of two-phase architecture, spatial distribution content, which is anticipated hold key increasing conductivity resolving within CSEs between CSEs/electrodes. Unfortunately, a comprehensive review exclusively discussing design, preparation application PEO/ceramic-based largely lacking, in spite tremendous reviews dealing broad spectrum polymers ceramics. Consequently, this targets recent advances CSEs, starting brief introduction, followed by conduction mechanism, methods, then an emphasis on compatibility. Afterward, applications transition oxides sulfur cathodes are summarized. Finally, summary outlook existing challenges future research directions proposed.

Sulfide-Based All-Solid-State Lithium–Sulfur Batteries: Challenges and Perspectives

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Март 28, 2023

Lithium-sulfur batteries with liquid electrolytes have been obstructed by severe shuttle effects and intrinsic safety concerns. Introducing inorganic solid-state into lithium-sulfur systems is believed as an effective approach to eliminate these issues without sacrificing the high-energy density, which determines sulfide-based all-solid-state batteries. However, lack of design principles for high-performance composite sulfur cathodes limits their further application. The cathode regulation should take several factors including insulation sulfur, well-designed conductive networks, integrated sulfur-electrolyte interfaces, porous structure volume expansion, correlation between account. Here, we summarize challenges regulating respect ionic/electronic diffusions put forward corresponding solutions obtaining stable positive electrodes.
