As the most promising candidate of solid electrolyte materials for future lithium batteries, oxide electrolytes with high–lithium‐ion conductivity have experienced a rapid development in past few decades. Existing are divided into two groups, i.e., crystalline group including NASICON , perovskite, garnet, and some newly developing structures, amorphous/glass Li 2 O–MO x (M = Si, B, P, etc.) PON ‐related materials. After historical perspective on general electrolytes, we try to give...
Space-charge layers are frequently believed responsible for the large resistance of different interfaces in all-solid-state Li batteries. However, such propositions based on presumed existence a Li-deficient space-charge layer with insufficient charge carriers, instead comprehensive investigation atomic configuration and its ion transport behavior. Consequently, real influence remains elusive. Here, we clarify role Li0.33La0.56TiO3, prototype solid electrolyte grain-boundary resistance,...
In this paper, the authors propose a magneto-optical tunable filter based on long-period fiber grating (LPG) coated with magnetic fluids (MFs) as ambient media. By applying field, center wavelength shift of attenuation band LPG is found large 7.4nm. The refractive index dependence MF external intensity measured and simulation results show that it well agreeable experimental observations.
Metal–organic framework derived hollow hierarchical porous carbon spheres (MHPCS) have been fabricated via a facile hydrothermal method combined with subsequent annealing treatment. Such MHPCS are composed of masses small bubbles size ∼20 nm and shells ∼5 thickness interconnected to each other. MHPCS/Se composite is developed as cathode for Li–Se cells delivers an initial specific capacity up 588.2 mA h g–1 at current density 0.5 C, exhibiting outstanding cycling stability over 500 cycles...
Abstract Through electrostatic interaction and high-temperature reduction methods, rGO was closely coated onto the surface of TiO 2 nanotubes. Even at a high temperature 700 °C, nanotube morphology (anatase) preserved because assistance rGO, which provides framework that prevents tubes from breaking into particles undergoing phase transformation. The rGO/TiO nanotubes deliver capacity (263 mAh g −1 end 100 cycles 0.1 A ), excellent rate performance (151 102 5 good cycle stability (206 after...
Abstract Moore's law predicts the performance of integrated circuit doubles every two years, lasting for more than five decades. However, improvements energy density in batteries lag far behind that. In addition, poor flexibility, insufficient‐energy density, and complexity incorporation into wearable electronics remain considerable challenges current battery technology. Herein, a lithium‐ion cable is invented, which insensitive to deformation due its use carbon nanotube (CNT) woven...

The substitution of Se for S as cathode rechargeable batteries, which confine selenium in porous carbon, attracts much attention a potential area research energy storage systems. To date, there are no reports about metal-organic frameworks (MOFs) to use Na-Se batteries. Herein, MOFs-derived nitrogen-doped carbon polyhedrons (NPCPs) have been obtained via facile synthesis and annealing treatment. is encapsulated into the mesopores homogeneously by melt-diffusion process form Se/NPCPs...
Abstract Flexible lithium‐ion batteries attract extensive attention in wearable electronics but are limited by severe capacity loss under extreme weather due to the poor flexible current collector. Herein, a horizontally oriented carbon nanotube macrofilm (HUCNM) with excellent electrical conductivity and tuned electrolyte wettability through engineering surface/interface of HUCNM is reported for foldable batteries, which exhibits high 700 mAh flexibility stable charge/discharge rate...
Lamellar hard carbon derived from holly leaf with enlarged pores of tiny graphite-like domains and meso-pores was prepared by hydrothermal followed high temperature pyrolysis process. Benefiting the nano-pores thin sheet structure meso-pores, delivered a reversible capacity 318 mAh g(-1) at current rate 20 mA excellent capability as anode sodium-ion battery. And method also confirmed an effective approach for betula platyphylla sophora japonica precursor respectively to synthesis lamellar domains.
Abstract In order to fully understand the lithium-ion transport mechanism in solid electrolytes for batteries, not only periodic lattice but also non-periodic features that disrupt ideal periodicity must be comprehensively studied. At present a limited number of such as point defects and grain boundaries are considered mechanistic studies. Here, we discover an additional type feature significantly influences ionic transport; this is termed “single-atom-layer trap” (SALT). prototype...
Among the various lead halide perovskites, inorganic cesium bromide (CsPbBr3) was considered as a promising candidate for new solar cells because of its unique photophysical properties and outstanding stabilities in high-humidity, high-temperature, or ambient atmosphere. However, efficiency is still quite limited due to inefficient charge transfer narrow spectra. In this work, we report that integrating P3HT/PCBM bulk heterojunction (BHJ) organic layer with CsPbBr3 films can sharply enhance...
