Abstract

Hierarchical Sn/SnO nanosheets assembled by carbon-coated hollow nanospheres with promising lithium and sodium storage performances.

Conversion‐Alloying Anode Materials for Sodium Ion Batteries

“…In order to further optimize the sodium storage performance, several SnO-based electrodes with diverse structures and morphologies have been synthesized, such as nanoflake arrays, 2D nanosheets, microflowers, hierarchical mesoporous microspheres, and hybrid nanocomposites with metals. [138][139][140][141][142] Among them, ultrathin SnO nanoflakes arrays with only ten layers grown on graphene were prepared by Chen et al through the typical hydrothermal route. A highly reversible capacity (580 mA h g −1 at a current density of 0.1 A g −1 ) and outstanding cycling stability (only 25% capacity fading over 1000 cycles at 1 A g −1 ) (Figure 9a-c) were achieved for this material.…”

Tin dioxide-based nanomaterials as anodes for lithium-ion batteries

“…Hydrothermal treatment followed by carbonization is the most common method for synthesizing SnO 2 /amorphous carbon nanomaterials. [228][229][230] There are mainly two synthesis routes of SnO 2 /amorphous carbon; one is to treat Sn 2+ or Sn 4+ salt with the precursor of carbon, [231][232][233][234][235][236] and the other is to deposit a carbon layer on the as-prepared SnO 2 nanostructures. 237,238 Conventional amorphous carbon can be derived from glucose, 239,240 sucrose 241,242 and many organic compounds.…”

Surface and Interface Modification of Electrode Materials for Lithium-Ion Batteries With Organic Liquid Electrolyte

“…And the activated porous carbon coated LFP (LFP/AC-P4) presents the increased Li-ions diffusion coefficient and low charge transfer resistance (Tian et al, 2020). Hence, it is disclosed that carbon coating is an important method to fabricate composites, which is able to be achieved by introducing a carbon source, such as graphene oxide (GO) (Huo et al, 2017), glucose (Zhang et al, 2017;Wang M. et al, 2019;He et al, 2020), sucrose (Chen et al, 2019;Park et al, 2019), pitch (Hsieh and Liu, 2020), cotton (Deng et al, 2019), ethylene glycol (Lin et al, 2008), and methyl orange (Yan et al, 2019), as raw materials. Besides, in the field of all-solid-state batteries, except the reconstruction of composite electrode materials, the controllable adjustment to composite solid electrolytes can effectively optimize the electrolyte interface.…”
