LFP@N-GA with (010) facet oriented LFP NPs embedded in N-GA provides both rapid Li<sup>+</sup> and electron pathways the electrode as well short diffusion length crystals.
The lack of suitable cathodes is one the key reasons that impede development aqueous zinc-ion batteries. Because inherently unsuitable structure and inferior physicochemical properties, low-valent V2O3 as Zn2+ host could not be effectively discharged. Herein, we demonstrate (theoretical capacity up to 715 mAh g-1) can utilized a high-performance cathode material by an in situ anodic oxidation strategy. Through simultaneously regulating concentration electrolyte morphology sample,...
With the urgent market demand for high-energy-density batteries, alloy-type or conversion-type anodes with high specific capacity have gained increasing attention to replace current low-specific-capacity graphite-based anodes. However, and large initial irreversible compared anodes, which consume most of Li+ in corresponding cathode severely reduces energy density full cells. Therefore, practical application these high-capacity it is develop a commercially available prelithiation technique...
Abstract Sodium metal anodes have attracted significant attention due to their high specific capacity (1166 mA h g −1 ), low redox potential ( − 2.71 V vs the standard hydrogen electrode), and abundant natural resources. Nevertheless, unstable solid electrolyte interphases (SEI) uncontrolled dendrite growth critically hinder commercialization. Notably, SEIs play a critical role in regulating Na deposition improving cycling stability of rechargeable batteries. Recently, SEI research on has...
A C@LiFePO4/carbon nanotubes microsphere composite (C@LFP/CNTs) with a unique double carbon (amorphous and graphitized conductive carbon) modified hierarchical porous structure for providing favorable kinetics both electron Li+ is reported. By combining large tap density improved mixed (electronic ionic) conductivity, high volumetric energy superior rate capacity as well excellent cycling stability are simultaneously achieved.
Growth of dendrites, the low plating/stripping efficiency Zn anodes, and high freezing point aqueous electrolytes hinder practical application Zn-ion batteries. Here, a zwitterionic osmolyte-based molecular crowding electrolyte is presented, by adding betaine (Bet, by-product from beet plant) to electrolyte, solve abovementioned problems. Substantive verification tests, density functional theory calculations, ab initio dynamics simulations consistently reveal that side reactions growth...
Silicon (Si), a promising candidate for next-generation lithium-ion battery anodes, is still hindered by its volume change issue (de)lithiation, thus resulting in tremendous capacity fading. Designing carbon-modified Si materials with void-preserving structure (Si@void@C) can effectively solve this issue. The preparation of Si@void@C, however, usually depended on template-based routes or chemical vapor deposition, which involve toxic reagents, tedious operation processes, and harsh...
Shell-core nanostructured carbon materials with a nitrogen-doped graphitic layer as shell and pristine black particle core were synthesized by carbonizing the hybrid containing in situ polymerized aniline onto black. In an N-doped layer, nitrogen atoms substitute at edge interior of graphene structure to form pyridinic N quaternary structures, respectively. As result, becomes more compact, showing curvatures disorder stacking. comparison nondoped carbon, one was proved be suitable supporting...

3D self-supported hierarchical core/shell structured MnCo<sub>2</sub>O<sub>4</sub>@CoS nanowire or nanosheet (MCO@CS-NW NT) arrays were designed for high-performance supercapacitors.
For the first time, a co-modification strategy using carbon and RGO was carried out to improve electrochemical performance of SiO-based materials for their use in LIBs.
In this work, mesoporous carbon-coated LiFePO4 nanocrystals further co-modified with graphene and Mg2+ doping (G/LFMP) were synthesized by a modified rheological phase method to improve the speed of lithium storage as well cycling stability. The structure was designed realized introducing bead milling technique, which assisted in forming sucrose–pyrolytic carbon nanoparticles template for generating mesopores. For comparison purposes, samples only (G/LFP) or (LFMP) pure (LFP) also prepared...
Structural modulation endows electrochemical hybrids with promising energy storage properties owing to their adjustable interfacial and/or electronic characteristics. For MXene-based materials, however, the facile but effective strategies for tuning structural at nanoscale are still lacking. Herein, 3D crumpled S-functionalized Ti3 C2 Tx substrate is rationally integrated Fe3 O4 /FeS heterostructures via coprecipitation and subsequent partial sulfurization induce a highly active stable...
Electron transfer and lithium ion diffusion rates are the key factors limiting storage in anisotropic LiFePO4 electrodes. In this work, we employed a facile solvothermal method to synthesize "platelet-on-sheet" LiFePO4/graphene composite (LFP@GNs), which is nanoplatelets situ grown on graphene sheets with highly oriented (010) facets of crystals. Such two-phase contact mode cross-linked form three-dimensional porous network favourable for both fast electron transports. As result, designed...
