Amorphous polymer derived silicon oxycarbide (SiOC) is an attractive candidate for Lithium ion battery anodes, as alternative to graphite, which limited a theoretical capacity of 372 mAh/g. However, SiOC tends exhibit poor transport properties and cycling performance result sparsely distributed carbon clusters inefficient active sites. To overcome these limitations, we designed fabricated layered graphene heterostructure by solvent assisted infiltration polymeric precursor into modified...
Aggregation of nanosized materials in composite lithium-ion-battery electrodes can be a significant factor influencing electrochemical behavior. In this study, aggregation was controlled magnetite, Fe3O4, via oleic acid capping and subsequent dispersion carbon black matrix. A heat treatment process effective the removal agent while preserving high degree Fe3O4 dispersion. Electrochemical testing showed that is initially beneficial delivering higher functional capacity, agreement with...
Lithium-ion batteries (LIBs) have been considered as promising electrochemical energy storage devices due to the high volumetric, gravimetric capacity and power density. The charge/discharge rate output of LIBs largely depend on transport property lithium-ions (Li-ions). Li-ions diffusion coefficient length are critical factors influencing LIBs. In this work, we present that silicon–carbon (Si–C) interfaces in an amorphous Si/C multilayer electrode promote along direction not only...
The core-void@shell architecture shows great advantages in enhancing cycling stability and high-rate performance of Si-based anodes. However, it is usually synthesized by template methods which are complex environmentally unfriendly would lead to low-efficiency charge mass exchange because the single-point van der Waals contact between Si core shell. Here, a facile benign one-step method synthesize multi-Si-void@SiO2 structure, where abundant void spaces exist multiple cores that multi-point...
Climate physical risks pose an increasing threat to urban infrastructure, necessitating urgent climate adaptation measures protect lives and assets. Implementing such measures, including the development of resilient infrastructure retrofitting existing systems, demands substantial financial investment. Unfortunately, a significant gap remains in funding adaptation, primarily due unprofitability stemming from conflict between long-term returns, uncertainty, complexity these adaptations...
Titanium dioxide (TiO2) is proposed as a promising anode material for lithium-ion batteries (LIBs) due to its highly stable structure and slight side reaction at the electrode/electrolyte interface. The low specific capacity slow Li-ion diffusion kinetics are major bottlenecks actual application of TiO2. It thus important exploit viable pathways enhance electrochemical performance understand corresponding mechanisms. In this work, high-quality amorphous TiO2 (TO) anatase (cTO) film...
Niobium pentoxide (Nb2O5) material is a promising anode for lithium-ion batteries (LIBs) due to the outstanding cycle performance and rate capability. However, relatively low capacity severely limits comprehensive performance. Generally, nanoscale engineering of morphology chemical composition Nb2O5 anodes employed improve electrochemical lithium storage. In this work, we promote reservable sheetlike by designing phase interfaces between nanodomains T-Nb2O5, M-Nb2O5, H-Nb2O5 phases, which...
ZnS hollow nanospheres with porous shells were successfully fabricated by a simple one-pot template-free hydrothermal route the assistance of trolamine. The mean diameter about 220 nm and pore size shell 3.2 exhibit large BET surface areas 129.9 m2 g−1. formation was definitely driven well-known Ostwald ripening process. morphology product could be controlled adjusting volume trolamine in ternary solution, which influence nucleation density rate growing region during initial stage reaction....
Constructing composite electrodes is considered to be a feasible way realize high-specific-capacity Li-ion batteries. The core–double-shell-structured Si@C@TiO2 would an ideal design for such batteries, considering that carbon (C) can buffer the volume change and TiO2 constrain structural deformation of Si. Although electrochemical performance shells themselves relatively clear, complexity multishell heterointerface always results in ambiguous understanding about influence on properties core...
CoO microspheres and metallic Co could be successfully synthesized by simply reacting cobalt acetate with a mixture solvent of ethylene glycol deionized water in hydrothermal process for different times. As the reaction proceeded, α-Co(OH)2, were produced. To understand phase evolution processes from α-Co(OH)2 to then Co, range time-dependent experiments carried out, intermediate products obtained at times investigated detail. The investigation revealed that actually evolved as precursor....

Abstract Tin/carbon (Sn/C) nanocomposite is considered as a promising anode material for high-performance Li-ion batteries (LIBs). However, since the carbon matrix always derived from high-temperature carbonization of polymers and Sn has low melting point (232 °C), nanoparticles in Sn/C tend to be heavily aggregated during process. It thus challenging synthesize well-dispersed matrix. Here, we report facile templating method encapsulate uniform amorphous tube (Sn@aCT). The electrode...
