Electronic Properties of Polyacenic Semiconductive Materials

在这项研究中，我们进行了多聚半导体材料的电子特性表征及其在高性能可充电电池中的应用。本研究（1995-1996）的结果如下：(1)确定了制备高性能二次电池碳阴极用多砷半导体材料的最佳条件。(2)在广泛的电化学测量的基础上，我们已经阐明了多聚半导体材料由于其结构的独特性，可以储存极大量的锂。(3)在已有知识的基础上，制备并表征了一种以多聚材料为阴极的锂离子可充电电池。(4)对多聚半导体材料进行了磁性、ESR和核磁共振测量，以观察掺杂锂的性质。

In this study, we have carrid out characterizations of the electronic properties of polyacenic semiconductive materials and their application to a high-performance rechargeable battery. The results of this study (1995-1996) are described below.(1) We have established the best condition for the preparation of polyacenic semiconductive materials that is used as a carbon cathod of high-performance secondary battery.(2) We have clarified on the basis of extensive electro-chemical measurements that polyacenic semiconductive materials can store an extremely large amount of lithium because of their structural uniquness.(3) On the basis of the knowledges we have found, a lithium ion rechargeable battery that has polyacenic materials as a cathod has been prepared and characterized.(4) Magnetic, ESR,and NMR measurements of polyacenic semiconductive materials have been carried out to look at the properties of doped lithium.
