中国储能技术的科学能力测度与国际比较

Measurement and international comparison of scientific performance of China in the energy storage technology

储能技术是引领人们走向绿色清洁低碳新未来的关键一环。为了全面了解并定位中国在储能技术领域的科学研究能力,本文综合运用文献计量和社会网络分析及可视化方法,从多维度和长时间跨度的视角综合测度中国在储能技术领域的科学能力并进行国际比较分析。研究结果表明该领域科学产出呈现显着增长;美国的科学产出与科学影响力都处于优势地位;中国科学产出位居榜首,但其科学影响力却相对不足;美国一直占居跨国家/地区科学合作网络的中心,中国逐渐成为合作网络的重要成员;"相变储能"、"超导磁储能"、"超级电容器"、"锂离子电池"、"储能材料"等是储能技术领域的重要研究主题。

Energy storage technology is the key that leads us to move into the green and low carbon future. To comprehensively understand and position the scientific performance of China in energy storage technology, we intended to combine bibliometric method with social network analysis techniques to investigate and compare the scientific performance of China in energy storage technology with some other countries from a multi - dimensional and longitudinal perspective. Results indicate that scientific output grows significantly worldwide. The scientific output and influence of the USA are both in a superior position compared to most of other countries. China holds the greatest number of scientific output, but its scientific influence is relatively insufficient. Although the USA and several European countries play significantly roles on internationally scientific collaboration, China exerts great influence on internationally scientific collaboration in recent years. We found that phase change energy storage, superconducting magnetic energy storage, super capacitor, lithium ion battery and energy storage materials are major research topics in this field.
