Web13 de abr. de 2024 · As shown in Fig. 7, by increasing the growth temperature from 750 °C to 1000 °C, more SWCNTs were obtained, and their areal density increased from ∼3 tubes/μm 2 to ∼10 tubes/μm 2. More catalyst particles were activated by the higher energy, and higher-density SWCNT networks were synthesized at higher temperatures. Density is a measure of the quantity of information bits that can be stored on a given length (linear density) of track, area of surface (areal density), or in a given volume (volumetric density) of a computer storage medium. Generally, higher density is more desirable, for it allows more data to be stored in the same physical space. Density therefore has a direct relationship to storage capacity of a given medium. Density also generally affects the performance within a particular m… Web17 de out. de 2024 · Currently, there still remains a big challenge for flexible supercapacitors: low energy density.
