Low dimensional graphite has recently attracted much attention. We have developed a new carbon preparation method "Template Cabdonization" which utilizes the interplanar spacing of montmorillonite for the preparation of 2-dimensional graphite. The aim of the present project is to produce carbon materials from this unique carbon. In the first year, we tried to synthesize K-GIC (potassium-graphite intercalation compound), and in the second year the application to the secondary battery was attempted. Some other clays were used for the purpose of clarifying the effect of the structure of host materials.1. The extent of crystallite breakage was quite small in the process of interalation and desorption for the case of low dimensional graphite.2. The lithium secondary battery derived from this carbon showed excellent behaviors in the stability and charge density.3. Taeniolite, which is highly crystalline clay, produced the carbon with high orientation and high crystallinity.4. On the other hand, saponite produced a very unique carbon which swells upon the contact with organic liguids.5. Magnetoresistance of the graphite from montmorillonite was determined. The value was much smaller than expected from the X-ray parameter. This suggests the low dimensional nature of this carbon.

近年来，低维石墨引起了人们的广泛关注。我们开发了一种新的碳制备方法--模板碳化法，利用蒙脱石的晶面间距制备二维石墨。本项目的目的是从这种独特的碳中生产碳材料。在第一年，我们尝试合成K-GIC（钾-石墨层间化合物），并在第二年尝试应用于二次电池。为了研究主体材料结构对粘土性能的影响，还使用了其它粘土.对于低维石墨，在插层和脱附过程中，微晶的破碎程度很小.由该碳材料制备的锂二次电池在稳定性和充电密度方面表现出优异的性能.带云母是一种结晶度很高的粘土，它产生的碳具有高取向性和高堆积度.另一方面，皂石产生了一种非常独特的碳，它在与有机液体接触时膨胀。测定了蒙脱石石墨的磁电阻。该值远小于X射线参数的预期值。这表明这种碳的低维性质。
