Sodium‐ion batteries (SIBs) have gradually become one of the most promising energy storage techniques in the current era of post‐lithium‐ion batteries. For anodes, transitional metal selenides (TMSe) based materials are welcomed choices , owing to relatively higher specific capacities and enriched redox active sites. Nevertheless, current bottlenecks are blamed for their poor intrinsic electronic...
Superlattice Films
Work function difference induces spontaneous charge donation and band bending at the interfaces of superlattices, which causes optimization effects of modulation doping and energy filtering, leading to remarkably enhanced thermoelectric performances. This optimizing strategy is successfully elucidated in 1T′‐MoTe2/Bi2Te3 superlattice films. Meanwhile, the rational manipulation of...
Interfacial charge effects, such as band bending, modulation doping, and energy filtering, are critical for improving electronic transport properties of superlattice films. However, effectively manipulating interfacial band bending has proven challenging in previous studies. In this study, (1T′‐MoTe2)x(Bi2Te3)y superlattice films with symmetry‐mismatch were successfully fabricated via the molecular...
With the pursuit of high‐energy‐density for lithium‐ion batteries (LIBs), the hidden safety problems of batteries have gradually emerged. LiNixCoyMn1−x−yO2 (NCM) is considered as an ideal cathode material to meet the urgent needs of high‐energy‐density batteries. However, the oxygen precipitation reaction of NCM cathode at high temperature brings serious safety concerns. In order to promote high‐safety...
