Measurements made at temperatures up to … WebThe high-resolution TEM image shows a large interlayer spacing of 0.38–0.44 nm, significantly outclassing the interlayer spacing of typical graphite. Moreover, the derived carbon nanofibers showed a high specific surface area of 438 m 2 g −1 and rich micro-pores (diameter of 0.6 and 1.5 nm) and meso-pores (diameter of 3.5 nm) ( Fig. 18d ).

Effect of Boron Doping on the Interlayer Spacing of Graphite - MDPI

WebIn most carbon materials, the average interlayer spacing d 002 is usually larger than that of graphite and approaches it gradually through high-temperature treatment. This is explained by the model of random mixing of graphitic and turbostratic stacking in a structural unit, as shown schematically in Fig. 1-14a . WebTask In this example you will determine the interlayer distance of graphite in the stacking direction using the method of Tchatchenko and Scheffler to account for van der Waals … WebJun 4, 2014 · Graphite is a common anode material for lithium-ion batteries, but small interlayer spacing makes it unsuitable for sodium-ion batteries.
