The chemical compositions of sei films formed on the interfaces of a3000 samples in different electrolytes during the first charging process are mainly li2co3 and lioco2r, but their textures are different. the sei films formed in ec - based electrolytes are thin and compact, which can prevent the solvated lithium ions from cointercalating between two graphene layers of the graphite crystallites effectively, therefore samples a3000 have small irreversible capacities and good compatibilities with this kinds of electrolytes. however, the sei films formed in pc - based electrolytes are thick but defective, which could not effectively prevent solvated lithium ions from intercalation, therefore sample a3000 shows large irreversible capacities in pc - based electrolytes and bad compatibilities with this kind of electrolytes

Because the photospheric temperature of carbon stars are less than 3000k and the temperature of rich - dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro - vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars

Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
