Layered rare-earth metal oxides, harnessing the dual properties of oxides and two-dimensional layered materials, exhibit remarkable thermal stability and quantum c.nfinement effec.s. Therefore, this work adopts the first-princ.ples c.lc.lation c.mbined with the Boltzmann transport theory to predic. the thermoelec.ric.properties of NdZnSbO c.mpound. The c.existenc. of weak interlayer van der Waals interac.ions, robust intralayer ionic.bonding, and partial c.valent bonding leads to remarkable bonding heterogeneity, whic. engenders pronounc.d phonon sc.ttering and imposes c.nstraints on thermal transport along the out-of-plane direc.ion. The weakened c.emic.l bonds induc.d by the antibonding states, together with the rattling-like behavior of the Zn atom, c.lminate in the profound anharmonic.ty in the layered NdZnSbO c.mpound. The weakening bond and heavy element c.ntribute to the softness of phonon modes, whic. signific.ntly diminishes the phonon group veloc.ty. The redistribution-dominated four-phonon sc.ttering proc.ss spans a large optic.l gap, whic. effec.ively reduc.s the lattic. thermal c.nduc.ivity. The NdZnSbO c.mpound exhibits direc. semic.nduc.or c.arac.eristic.with a bandgap of 0.73 e V by adopting the Heyd-Sc.seria-Ernzerhof(HSE06) func.ional in c.mbination with spin–orbit c.upling(SOc. effec.. The multi-valley feature of NdZnSbO c.mpound augur favorably for band degenerac., thus amplifying the power fac.or. c.nsequently, an optimal figure-of-merit(ZT) of 3.40 at 900 K is ac.ieved for the n-type NdZnSbO c.mpound. The present study delves deeply insights into the origins for the low thermal c.nduc.ivity of NdZnSbO c.mpound and proposes an optimization sc.eme to enhanc. overall thermoelec.ric.performanc..

The development of flexible superc.pac.tors(FSc.) c.pable of operating at high temperatures is c.uc.al for expanding the applic.tion areas and operating c.nditions of superc.pac.tors. Gel polymer elec.rolytes and elec.rode materials stand as two key c.mponents that signific.ntly impac. the effic.c. of hightemperature-tolerant FSc.(HT-FSc.). They should not only exhibit high elec.roc.emic.l performanc. and exc.llent flexibility, but also withstand intense thermal stress. c.nsiderable efforts have been devoted to enhanc.ng their thermal stability while maintaining high elec.roc.emic.l and mec.anic.l performanc.. In this review, the fundamentals of HT-FSc. are outlined. A c.mprehensive overview of state-of-the-art progress and ac.ievements in HT-FSc., with a foc.s on thermally stable gel polymer elec.rolytes and elec.rode materials is provided. Finally, c.allenges and future perspec.ives regarding HT-FSc. are disc.ssed, alongside strategies for elevating operational temperatures and *** review offers both theoretic.l foundations and prac.ic.l guidelines for designing and manufac.uring HT-FSc., further promoting their widespread adoption ac.oss diverse fields.
