Eutectic electrolytes have been widely used in low-temperature metal-ion batteries (MIBs) due to their good performance regardless of seasonal and regional changes. Durable MIBs rely on the constitution, proportion, solvation-structure construction eutectic maintain high ionic conductivity electrochemical stability. Despite rapid advances electrolytes, some key issues, including fundamental mechanisms, theoretical models, aqueous/non-aqueous controversies, challenges at sub-zero...
Sodium-ion batteries (SIBs) are attracting worldwide attention due to their multiple merits including abundant reserve and safety. However, industrialization is challenged by the scarcity of high-performance carbon anodes with high specific capacities. Here, we report metal-assisted microcrystalline structure regulation materials achieve high-capacity sodium storage. Systematic investigations in situ thermal-treatment X-ray diffraction spectroscopies uncover mechanism constructing steric...
The fine regulation of catalysts by the atomic-level removal inactive atoms can promote active site exposure for performance enhancement, whereas suffering from difficulty in controllably removing using current micro/nano-scale material fabrication technologies. Here, we developed a surface atom knockout method to an alloy catalyst. Taking Cu 3 Pd as example, it refers assemble battery and Zn cathode anode, charge process which proceeds at about 1.1 V, equal theoretical potential difference...
This review summarizes the significance, behaviors, and passivation strategies of defects under electric field in perovskite materials optoelectronic devices.
Lead-free multiferroic ceramics of 0.75Bi1−xNdxFeO3 − 0.25BaTiO3 + 1 mol. % MnO2 were prepared by a conventional ceramic technique and their structure, piezoelectricity, multiferroicity studied. The sintered at 890–990 °C possess pure perovskite structure. A morphotropic phase boundary rhombohedral monoclinic phases is formed x = 0.05. small amount Nd improves the ferroelectric piezoelectric properties ceramics. ferroelectric-paraelectric transition becomes gradually diffusive with...
Multifunctional materials based on rare earth ion doped ferro/piezoelectrics have attracted considerable attention in recent years.
Transition-metal selenides have been considered as one of the most promising anode materials for sodium-ion batteries (SIBs) due to their high theoretical capacity and excellent rate performance. However, rapid decay poor cycling stability limit practical application SIBs. Carbon coating is effective ways solve above problems, but thickness uniformity layer are difficult control. Herein, we successfully synthesize metal–organic framework (MOF)-derived porous N-doped carbon nanocubes...
Lead‐free multiferroic ceramics of BiFeO 3 ‐ BaTiO Bi 0.5 Na TiO have been prepared by a conventional ceramic technique. The microstructure, multiferroic, and piezoelectric properties the studied. sintered at 1000°C for 2 h possess pure perovskite structure morphotropic phase boundary rhombohedral tetragonal phases is formed x = 0.02. After addition , two dielectric anomalies are observed high temperatures ( T m ~ 510°C–570°C 720°C). transition around becomes wider gradually with increasing...
Quasi-two-dimensional (quasi-2D) mixed-halide perovskites are a requisite for their applications in highly efficient blue perovskite light-emitting diodes (PeLEDs) owing to strong quantum confinement effect and high exciton binding energy. The pace of quasi-2D PeLEDs is hindered primarily by two factors: challenges precisely managing the phase distribution defect-mediated nonradiative recombination losses. Herein, we utilize 2,2-diphenylethylamine (DPEA+) with bulky steric hindrance disturb...
