Co9 S8 is considered a promising candidate as the anode material in lithium-ion batteries (LIBs) because of its remarkable electrical conductivity, high theoretical capacity, and low cost. However, practical application greatly restricted poor cycling stability rate performance, which result mainly from large volume expansion dissolution polysulfide intermediates during charge/discharge process. In this report, embedded N-rich carbon hollow spheres are successfully designed synthesized...
The application of hematite in lithium-ion batteries (LIBs) has been severely limited because its poor cycling stability and rate performance. To solve this problem, nanoparticles with oxygen vacancies have rationally designed by a facile sol–gel method sequential carbon-thermic reduction process. Thanks to the existence vacancies, electrochemical performance as-obtained is greatly enhancing. When used as anode material LIBs, it can deliver reversible capacity 1252 mAh g−1 at 2 C after 400...
Abstract Uniquely structured CoS/N‐doped carbon@MoS 2 (denoted as CoS/NC@MoS ) hollow spheres were successfully synthesized by using a well‐designed N‐rich Co‐metal organic framework (ZIF‐67) precursor and template. Owing to the good mechanical stability conductivity of carbon spheres, N‐doped carbon, Co−Mo bonds, as‐prepared composites exhibit outstanding electrochemical performance both in electrocatalytic energy storage applications. An overpotential 77 mV at 10 mA cm −2 , Tafel slope 67...

A Ge/C spongelike composite is prepared by the facile and scalable single-step pyrolysis of GeOx/ethylenediamine gel process, which has a feature with three-dimensional interconnected pore structures hybridized nitrogen-doped carbon. detailed investigation shows that in sponge formed for departure gaseous products at evaluated temperature. As an anode lithium ion batteries, obtained exhibits superior specific capacity excess 1016 mA h g–1 100 after cycles. Moreover, amorphous electrode also...
Cobalt sulfides are good candidate anode materials for lithium ion storage their high theoretical capacities. However, electrochemical performance is restricted by volume change during the cycles, leading to a sharp capacity fading in subsequent process. To overcome these disadvantages, ultrathin nanosheets assembled hierarchical cobalt sulfides@C hollow spheres fabricated hydrothermal and carbon enwrapping strategy. The as-prepared Co9S8@C deliver an enhanced with both long-term cyclability...
Size controllable synthesis of GeO<sub>x</sub> hollow spheres was achieved using a solvothermal reaction. The exhibit excellent lithium storage properties.
Flower-like α-Fe2O3−δ nanostructures have been successfully synthesized via a one-step hydrothermal method. The as-prepared exhibited good cyclability and rate performance. discharge capacity could retain as high 1192.4 mAh g−1 (current density: 400 mA g−1) after 800 cycles, which is higher than the theoretical value of hematite. When current density increased to 3200 g−1, reversible about 660 g−1. electrochemical performance be attributed combination both nano-structuring strategy oxygen...
Abstract A molecular design strategy is used to construct ordered mesoporous Ti 3+ ‐doped Li 4 5 O 12 nanocrystal frameworks (OM‐Ti ‐Li ) by the stoichiometric cationic coordination assembly process. 4+ /Li + ‐citrate chelate designed as a new precursor, in which citrate can not only stoichiometrically coordinate with homogeneously at atomic scale, but also interact strongly PEO segments Pluronic F127. These features make co‐assembly and crystallization process more controllable, thus...
Abstract As an important regulatory method, the phase engineering strategy is widely used to develop functional materials with desired properties. Herein, we combine a solvothermal method post‐annealing treatment controllably synthesize multifunctional MoSe 2 flower‐like nanostructures (FNSs) in different crystal phases. Based on phases of FNSs, systematically investigate their performance lithium‐ion storage, hydrogen evolution reaction (HER), and hydrogenation nitrophenol. The results show...
