基于SCI-E及SSCI数据库,检索并提取1991—2015年间物理储能、化学储能、电磁储能和相变储能4大技术领域的论文数据,试图整合统计分析、文本挖掘、突现检测算法和共现网络可视化方法,旨在从整体视角实现对4大储能技术领域科学研究景观的辨识及演化探析。此外,还定义了稳定系数和创新系数,以测度储能关键词共现网络的稳定性演化和创新性演化。研究发现:储能领域的研究问题是高度集中的,“飞轮”、“锂离子电池”、“超级电容器”和“相变材料”是研究热点,“压缩空气储能”、“能源存储”、“锂离子电池”、“导热性”和“热发电”是研究前沿;储能关键词共现网络扩张明显,知识结构也不断演化,储能研究仍处于创新热络期。
Based on the SCI-E and SSCI databases, the dissertation extracts and extracts the dissertation data of four major technical fields of physical energy storage, chemical energy storage, electromagnetic energy storage and phase change energy storage from 1991 to 2015, and attempts to integrate statistical analysis, text mining, burst detection algorithm And co-occurrence network visualization method, aimed at realizing the identification and evolution of the scientific research landscape in the four major storage technologies from a holistic perspective. In addition, the stability coefficient and innovation coefficient are also defined to measure the evolution and innovation of co-occurrence network of energy storage keywords. The research found that the research questions in the field of energy storage are highly concentrated. The research topics of “energy storage”, such as “flywheel”, “lithium ion battery”, “supercapacitor” and “phase change material” Energy storage “,” lithium ion battery “,” thermal conductivity “and” thermal power generation "are the frontiers of research; storage key words coexistence network expansion obvious knowledge structure Evolving, energy storage research is still in the heat of innovation.
