Abstract Amorphous nanomaterials recently have been demonstrated as a new type of high-power electrodes for many electrochemical energy-storage devices owing to their structural advantages of large surface area, shortened ion-diffused pathway, rich surficial defects and loosely packed structure; However, it is still challenging to prepare amorphous nanomaterials on a large scale via low-cost sol-gel method due to the easy amorphous-to-crystalline transformation upon post calcination process. Her...

Abstract The development of high-energy lithium-ion and sodium-ion capacitors (LICs and SICs) is still a challenge due to the kinetics mismatch between the insertion/deinsertion anode and adsorption/desorption cathode. Here, high-level N/P-doped Sn-carbon nanofibers (Sn-NP-CNFs) were fabricated via an electrospinning technique followed by pre-oxidization and carbonization. The N/P-doping increased the defects and carbon interlayer distance to inhibit the precipitation and volume expansion of the...

This study intends to obtain a kind of polymer-infiltrated ceramic-network (PICN) composite with improved performance for dental restoration. Porous ceramic network was prepared via compressing feldspar powders, followed by resin infiltration using Bis-GMA/TEGDMA or UDMA/TEGDMA mixtures to obtain PICN composites after thermocuring. The sintering parameters (temperature, duration) for the formation of feldspathic network with proper porosity were investigated. The ratios of resin mixtures were ad...

Abstract Low-cost sodium ion batteries (SIBs) have shown hopeful perspective for large-scale energy storage systems. However, the development of carbon anode materials with high gravimetric and volumetric capacity is still a challenge. Herein, we propose a novel dense and N, P co-doped carbon derived from high density crosslinked bacterial cellulose (BC) with hexachlorocyclotriphosphazene (HCCP), which simultaneously combines high gravimetric and volumetric capacity. The as-prepared electrode de...

Abstract Microstructure design combined with high-level heteroatoms doping has been considered the leading approach for preparing the high-performance carbon anodes for sodium-ion batteries (SIBs). Herein, a hollow porous carbon sphere (NP-HPCS) that exhibits a high N, P co-doping level (6.05 at% for N, 5.19 at% for P) and a large microporous specific area (339 m2 g-1) is reported. The microporous and N, P co-doping synergistic construction of the NP-HPCS was achieved by a high-efficiency chemic...
