Abstract Aqueous zinc ion batteries (ZIBs) are troubled by the severe Zn dendrite growth and side reactions, manifesting as low coulombic efficiency poor cyclic stability. Electrolyte engineering is regarded an efficient method to improve metal reversibility. Herein, a distinctive electrolyte regulation strategy demonstrated for long‐lasting ZIBs through construction of competitive solvation structures. In composite aqueous system, insoluble LiNO 3 in dimethyl carbonate (DMC) introduced...
Abstract N -type polycrystalline SnSe is considered as a highly promising candidates for thermoelectric applications due to facile processing, machinability, and scalability. However, existing efforts do not enable peak ZT value exceeding 2.0 in n SnSe. Here, we realized significant enhancement by leveraging the synergistic effects of divacancy defect introducing resonance level into conduction band. The increased density states resulting from tungsten boost Seebeck coefficient. combination...
Abstract The single parabolic band (SPB) model has been widely used to preliminarily elucidate inherent transport behaviors of thermoelectric (TE) materials, such as their structure and electronic thermal conductivity, etc. However, in the SPB calculation, it is necessary determine some intermediate variables, Fermi level or complex Fermi-Dirac integrals. In this work, we establish a direct carrier-concentration-dependent restructured model, which eliminates integrals calculation emerges...
Polycrystalline SnSe materials with ZT values comparable to those of crystals are greatly desired due facile processing, machinability, and scale-up application. Here manipulating interatomic force by harnessing lattice strains was proposed for achieving significantly reduced thermal conductivity in polycrystalline SnSe. Large static strain created dislocations stacking faults causes an effective shortening phonon relaxation time, resulting ultralow conductivity. A combination band...
The direct Z-scheme photocatalytic heterojunction, possessing type II band alignments but simultaneously realizing the spatial separation of photogenerated electrons and holes (PEHs) well-preserved strong redox ability, is a promising strategy for solving energy environmental issues. However, conventional method solely relying on direction interfacial electric field (IEF) to determine often different with experiments. Properly evaluating constructing remain limited. Herein, combining hybrid...
Abstract SnTe is an emerging Pb‐free thermoelectric compound that has drawn significant attention for clean energy conversion. Chemical doping routinely used to tailor its charge carrier concentration and electronic band structures. However, the efficacy of dopants often limited by their small solubility. For example, only 0.5% Ag can be incorporated into matrix. Yet, significantly more (>7%) dissolved if alloyed with AgSbTe 2 . This large enhancement solubility understood from a chemical...
The high-throughput (HT) computational method is a useful tool to screen high-performance functional materials. In this work, using the deformation potential under single band model, we evaluate carrier relaxation time and establish an electrical descriptor (χ) characterized by effective masses based on simple rigid approximation. can be used reasonably represent maximum power factor without solving electron Boltzmann transport equation. Additionally, Grüneisen parameter (γ), of lattice...

MnTe has been considered a promising candidate for lead-free mid-temperature range thermoelectric clean energy conversions. However, the widespread use of this technology is constrained by relatively low-cost performance materials. Developing environmentally friendly thermoelectrics with high and earth-abundant elements thus an urgent task. candidate, yet peak ZT 1.4 achieved so far less satisfactory. Here, remarkably 1.6 at 873 K in system realized facilitating multiple valence band...
SnTe, emerging as an environment-friendly alternative to conventional PbTe thermoelectrics, has drawn significant attention for clean energy conversion. Here, a high peak figure of merit (ZT) 1.45 at 873 K in Ge/Bi codoped SnTe-AgBiTe2 alloys is reported. It demonstrated that the existence Ge, Bi, and Ag facilitate band convergence resulting remarkable enhancement Seebeck coefficient power factor. Simultaneously, localized lattice imperfections including dislocations, point defects,...
