We have developed an analysis method of carbon components in carbon composite materials through selective gasification, based on their differences in crystallinity and reactivity with steam as a gasifying agent. This paper shows the results of application of the method to two different types of carbon composite materials: carbon fiber composites and anode electrode materials for lithium-ion batteries. Using this method, we successfully quantified the amount of each carbon component in the carbon composites with high accuracy. The technique described in this paper has a potential not only for quantitative analysis of carbon composites, but also for evaluation of microstructures of carbon products, such as carbon fibers, needle cokes and so on.
