Development of lithium ion battery is reviewed. Lithium ion battery has been used widely for note book personalcomputers, cellular phones and other applications. Annual sales amounts have reached to about 200 billion yens in 19<BR>This new battery system was found in 1984 by Asahi Chemical Co. Extensive work has been carried out to improvecarbonaceous material for negative electrode.<BR>By this improvement, discharge capacity of lithium ion battery (Cylindrical Type 18650) has been increasedfrom 920mAh to 1600mAh in these 5 years. Future trend of technology is also reviewed.

携帯電話,ノートパソコン,カムコーダー等の電源として広く用いられているリチウムイオン二次電池の開発経緯と技術動向について述べる。導電性高分子ポリアセチレンの研究がこのリチウムイオン二次電池の開発の原点であった。ポリアセチレンを二次電池の負極に用いようとの試みが炭素質材料負極へと展開し,ほぼ同時期に見いだされた正極材料であるリチウムイオン含有金属酸化物LiCoO<SUB>2</SUB>と組み合わされ,現在のリチウムイオン二次電池が完成した。商品化されて以降の電池特性の改良,特に容量の向上は著しく,現在では商品化当初の約2倍になっている。この容量向上は主として負極炭素質材料の改良により達成されてきた。この背景には&pi;電子化学という新しい学問領域の進歩があり,次々に新しい炭素質材料が開発されてきた。<BR>今後,これらの改良開発によりリチウムイオン二次電池の特性はさらに改善されていくものと思われる。

In this research, authors will clarify the transformation process and the present condition of the historical block of Beijing Outer Castle as a series of researches on urban fabric. The objective of this article is to evaluate living environment of Xuanxibei district, focusing on the space formation of da-za-yuan based on field studies. Xuanxibei district is designated for ‘Cordination Area of Historic Landscape’, but also for ‘Peng-hu-qu, Area’ to be improved. The district still maintains the traditional house type called si-he-yuan, but most of them is occupied by several families. The major points which this article clarifies are the following. 1. There are many historical cultural heritages in Beijing Outer Castle where five “Historical Cultural Reserve Areas” and three “Historical Appearance Cooperative Areas” are designated. On the other hand, most of large-scale traditional courtyard house sìhéyuàn were occupided by many families and “Peng-hu-qu” which is consisted of many ‘peng-hu-fang’(small dwelling unit) was formed. Targeted study area Xuanxibei is a district designated both as a “Historical Cultural Reserve Areas” and a “Peng-hu-qu”’, and is a district that requires immediate living environment improvement. 2. In Xuanxibei district, the street network is not as neat as the inner castle at the stage of Qianlong Jingcheng Quantu(1750)and there are many vacant lands. Since the end of the 18th century, halls and the sìhéyuàn were gradually built, forming a curved street network. As of 1955, the entire district was almost completely built, and the same street network as the present was established. The street is divided into 3 levels. a street where stalls and stalls selling vegetables and fruits come and go, a street for residents to pass through, and a street leading to each dwelling house. 3. As shown in Fig. 5. The whole area is densely populated, and many of the daily activities like the public trash cans, public toilets and private storage etc. are carried out in the streets and community facilities. It is necessary to consider improvement of the living environment besides clearance type redevelopment. 4. Since the establishment of the People's Republic of China, many people flow into Xuanxibei district. As of 1955, the form of sìhéyuàn was maintained, but it gradually became a "large miscellaneous house" in which several families coexist. "Peng-hu-fang" has been rapidly increasing since the early 1960s. When moving in, it is a one-room residence or two-room residence, and then a kitchen, bathroom, warehouse, etc. are added between the courtyard and the adjacent house. 5. The district government and developers are promoting a redevelopment project, but have not progressed as planned. The forced evictions of the residents and the demolition of their homes were the main causes of the people's backlash. In addition, the number of 2287 units requested to move make it difficult to form a consensus.  It would be unrealistic to inflate all the residents and redevelop the entire district, as it would be costly to compensate. Due to the building restrictions, the volume can not be increased, and there is little benefit for developers. In order to revitalize the district, a new method of improving the living environment at the on-site may be necessary. Further investigation is needed as to what will happen to Xuanxibei district.
