| Summary: | The bottlenecks in the development of the three major emerging industries (electric vehicles, new energy, smart grid) all point to energy storage technology. The development of electrochemical energy storage technology oriented to transportation is developing rapidly. Web of Science database is used to retrieve global research works related to electrochemical energy storage and adopt scientometric analysis with the help of CiteSpace software. The visualization results show that the global research output of energy storage continues to grow rapidly, and China has become the largest contributor, while the United States ranks second. (1) The network density of research related to ``Electrochemical energy storage'' from 2011 to 2021 is 0.0408; (2) In the keyword co -occurrence network of ``Electrochemical energy storage'' from 2011 to 2021, the network density of China is 0.0071, and the center of the network is 0.0071. (2) In the keyword co -occurrence network in the subject area of ``Electrochemical energy storage'' from 2011 to 2021, the Chinese network density is 0.0071 with a centrality of 0.6; the American network density is 0.0108 with a centrality of 0.01; (3) Using the keyword proliferation detection technique (Burst analysis) in CiteSpace software, it is found that there are large differences between the research hotspots in the field of electrochemical energy storage in China and the United States, especially in supercapacitors and superconducting materials and lithium -ion batteries. (4) Overlay mapping shows that the China has crossed over with multiple disciplines in the field of electrochemical energy storage; (5) Some recent research activities in the field of electrochemical energy storage in China and the United States have overlap, mainly focusing on the research of nano -engineered materials for batteries and supercapacitors. |
