摘要

锂离子电池的研究与开发具有诱人的商业前景.以金属锂为负极的锂二次电池存在着充放电循环寿命短和使用安全性能差等诸多问题,解决的途径之一是采用嵌锂化合物替代金属锂作为负极材料.其中,以具有贮锂功能的碳素材料作为负极的锂离子电池,不仅具有较高的电容量和较长...

Abstract

A novel of carbon gas coke prepared from natural gas by thermoplasma technology has been studied. The cyclic voltametry and charge discharge test for the Li/gas coke cell demonstrated that this gas coke material has a good performance of the Li ion intercalation characteristic. X ray diffraction pattern of the gas cokeis showed that the structure of gas coke is similar to the graphite and collapsed from order to disorder during the charge discharge cycles. The gas coke electrode give rise to a new diffraction peak at a low angle after intercalating Li ion and a reversible capacity with 235 mAh/g is showed. The first charge discharge efficiency was about 58.3%.
