## Description

- description: 'Lithium-sulfur (Li-S) batteries have attracted considerable attention
    as a promising energy storage technology. However, the low loading and utilization
    of sulfur result in the poor practical energy density of these batteries, which
    has hindered their extensive application. Herein, we demonstrate the fabrication
    of molecular pairwise/sandwich-like assembly of TaO3/rGO, which can be pelletized
    into a self-supported cathode to improve sulfur loading and utilization. This
    unique pairwise/sandwich-like heterostructure of TaO3/rGO is produced through
    a solution process via self-assembly and identified by X-ray diffraction analysis/simulation
    and TEM observations. The molecular-scale heterostructure maximizes attractive
    features of the TaO3 nanomesh: crystalline open channels, polar Ta-O bonds, Lewis
    acid surfaces and largely exposed active sites, by combining with electrically
    conductive rGO. As a benefit, the heterostructure exhibited fast Li+ transfer,
    effective confinement of polysulfides and high catalytic activity for the conversion
    of lithium polysulfides and uniform deposition of Li2S, thereby contributing to
    high sulfur utilization. As a result, the Li-S batteries assembled with these
    self-supported cathodes achieved a high areal capacity of 10.5 mAh cm˗2 at 2 mA
    cm˗2. This versatile strategy of fabricating electrodes with high loading of powder-like
    active materials can be applied to various energy storage systems, such as alkali
    metal batteries, promoting their practical application. '
