As the anode material, natural graphite, polymer-coated natural graphite, carbon-coated natural graphite and artiˆcial graphite were employed. In order to examine the eŠect of solid electrolyte interface (SEI), these samples were exposed to the cycles of charge/discharge. The gas desorption behavior of these samples was investigated by using a technique of thermal desorption spectroscopy. The amount of desorbed gasses signiˆcantly increased after a charge/discharge cycle. The increase of the desorbed amount was associated with gas desorption from SEI formed in theˆrst cycle. The amount of desorbed gasses increases with an irreversible capacity in theˆrst charge/discharge cycle. The irreversible capacity of surface-coated graphite and artiˆcial graphite was lower than that of natural graphite. The surface coating resulted in the decrease of the amount of desorbed gasses and irreversible capacity. The atomic composition was measured by auger electron spectroscopy. Carbon, Oxygen, ‰uorine and phosphorus were observed after a charge/discharge cycle.

“…Amount of deuterium incorporated in the film was measured with thermal desorption spectrometry (TDS) [11]. In the TDS, the sample was heated linearly from room temperature (RT) to 1273 K with a heating rate of 0.5 K/s and kept at 1273 K for 30 min, and the desorption rate of gases from the sample was measured with a quadruple mass spectrometer (QMS).…”

Reduction of Gas Desorption in Graphite Anode Used in Lithium Ion Battery by Hydrogen Plasma Irradiation

et al. 2011

In order to reduce amount of electrolyte solvent desorbed from anode material in lithium ion battery, hydrogen plasma irradiation for the anode material was conducted. During the irradiation, the sample was negatively biased. Natural graphite sample after the hydrogen plasma irradiation was soaked in propylene carbonate (PC) used as electrolyte solvent. Then, the gas desorption behavior was investigated by using a technique of thermal desorption spectroscopy (TDS). The amount of gasses in the sample irradiated by hydrogen plasma due to the PC was reduced compared with case in the non-irradiated sample. The reduction by the irradiation became large with the increase of negative bias voltage. The reduction also increased with the ‰uence and became roughly constant in the higher ‰uence regime. In order to discuss this mechanism, the sample without the soaking in PC was heated up to 1173 K. H 2 desorption at high temperature region, around 1173 K, increased for the irradiated sample, compared with non-irradiated sample. This result suggests that implanted hydrogen ions form C H bond with carbon of active sites and then the C H bond might prevent the PC from adsorbing during the subsequent soaking.
