How are microcrystalline structures of carbon materials characterized?

The microcrystalline structures of carbon materials were characterized using an X-ray diffractometer (Ultima IV, Japan) with Cu-K α radiation (1.5405 Å), and Raman spectra using a confocal micro Raman spectrometer (Renishaw, inVia Reflex, England). The nitrogen adsorption–desorption isotherms were recorded using a Micromeritics ASAP2460 analyzer.

Is a carbon microcrystalline hybridization strategy suitable for a coal-based carbon material?

Herein, we propose a carbon microcrystalline hybridization strategy to construct a coal-based carbon material with the assistance of sucrose, which shows both high Na-storage capacity and high ICE.

Which microcrystallite has the highest na-storage capacity?

The electrochemical characteristics were studied for hybrid microcrystallite with various sucrose-to-coal ratios, with LCS-73 exhibiting the highest Na-storage capacity of 356 mAh g −1 and an ICE value of 82.9% based on optimum pseudo-graphitic regions and adequate conductivity.

What is microcrystalline hybridization?

In general, the microcrystalline hybridization is a very simple but effective strategy to develop advanced carbon anode materials combining excellent Na-storage performance and low cost for practical SIBs, which can also be extended to the microcrystalline structure adjustment of carbonaceous materials in other secondary ion batteries.

What are microcrystalline hybridized carbon materials (LCS)?

The microcrystalline hybridized carbon materials (LCS) were prepared from two precursors, lignite coal (Xin Jiang province, China) and sucrose (Tianjin Yongda Co., China, 99.6%). Typically, lignite coal and sucrose were mixed by the ball-milling method in a certain ratio followed by compression to form tablets.

Which X-ray spectrometer characterized microcrystalline structures of carbon materials?

The microcrystalline structures of carbon materials were characterized by X-ray diffractometer (Ultima IV, Japan) using Cu-Kα radiation (1.5405 Å) and Raman spectra using a Confocal micro Raman spectrometer (Renishaw, inVia Reflex, England).
