Advanced Materials for Energy Storage

Since the discovery of mechanically exfoliated graphene in 2004, research on ultrathin two-dimensional (2D) nanomaterials has grown exponentially in the fields of condensed matter physics, material science, chemistry, and nanotechnology. Highlighting their compelling physical, chemical, electronic, and optical properties, as well as their various potential applications, in this Review, we summarize the state-of-art progress on the ultrathin 2D nanomaterials with a particular emphasis on their recent advances. First, we introduce the unique advances on ultrathin 2D nanomaterials, followed by the description of their composition and crystal structures. The assortments of their synthetic methods are then summarized, including insights on their advantages and limitations, alongside some recommendations on suitable characterization techniques. We also discuss in detail the utilization of these ultrathin 2D nanomaterials for wide ranges of potential applications among the electronics/optoelectronics, electrocat...

Concrete-like high sulfur content cathodes with enhanced electrochemical performance for lithium-sulfur batteries

Iron oxides are regarded as promising anodes for both lithium-ion batteries (LIBs) and potassium-ion batteries (KIBs) due to their high theoretical capacity, abundant reserves, and low cost, but they are also facing great challenges due to the sluggish reaction kinetics, low electronic conductivity, huge volume change, and unstable electrode interphases. Moreover, iron oxides are normally prepared at high temperature, forming large particles because of Ostwald ripening, and exhibiting low electronic/ionic conductivity and unfavorable mechanical stability. To address those issues, herein, we have synthesized ultra-small Fe3O4 nanodots encapsulated in layered carbon nanosheets (Fe3O4@LCS), using the coordination interaction between catechol and Fe3+, demonstrating fast reaction kinetics, high capacity, and typical capacitive-controlled electrochemical behaviors. Such Fe3O4@LCS nanocomposites were derived from coordination compounds with layered structures via van der Waals's force. Fe3O4@LCS-500 (annealed at 500 °C) nanocomposites have displayed attractive features of ultra-small particle size (∼5 nm), high surface area, mesoporous and layered feature. When used as anodes, Fe3O4@LCS-500 nanocomposites delivered exceptional electrochemical performances of high reversible capacity, excellent cycle stability and rate performance for both LIBs and KIBs. Such exceptional performances are highly associated with features of Fe3O4@LCS-500 nanocomposites in shortening Li/K ion diffusion length, fast reaction kinetics, high electronic/ionic conductivity, and robust electrode interphase stability.

Ultra-small Fe3O4 nanodots encapsulated in layered carbon nanosheets with fast kinetics for lithium/potassium-ion battery anodes

Self-assembly nanostructures of one-dimensional antimony oxide and oxychloride

Nitrogen-Doped Carbon-Coated Bimetal Selenides for High-Performance Lithium-Ion Storage through the Self-Accommodation of Volume Change

A new ternary metal oxide (Cr2Mo3O12) anode for Li-ion batteries is reported in this work. Experimental conditions such as reaction temperature, reaction time, and reactant concentration have all been investigated. The product can be obtained with sheet-like or rod-like morphology with/without the presence of a graphene support. The Cr2Mo3O12/graphene rod-on-sheet composite is found to be more suitable for Li-storage compared to the Cr2Mo3O12/graphene sheet-on-sheet composite and pristine Cr2Mo3O12 nanosheets/nanorods. The rod-on-sheet composite delivers a large reversible capacity of 988 mA h g−1 after 50 cycles at a current density of 100 mA g−1 and a good rate capability. Moreover, a preliminary Li-storage mechanism is also explored and suggested.
