In order to reduce CO2 emission and avoid the greenhouse effect, a lot of countries, including U.S., Japan, China, have already carried out development policy to promote green vehicles. For the upcoming era of electric vehicles, this paper would focus on the research trend of LiFePO4, a type of battery technology for EVs, and use visual tool to show the flow of knowledge mainstreams. Through this study, one can obtain basic domain knowledge of LiFePO4 battery, and capture the main development trajectory in the short times.
Citation network in academic articles have been developed. This paper use main path analysis and h-index to find out the influential articles and authors in the field of LiFePO4. We found three active knowledge mainstreams in recent ten years. They are synthesis of LiFePO4 particles, Lithium extraction/insertion process in LiFePO4, and Improvement of LiFePO4 electrochemical performance, such as enhancing electronic conductivity or Li ion diffusion to reach high electric capacity.
Through growth curve analysis with academic articles, we found LiFePO4 is on the growing stage, and it’s time to commercialize. In the future, development of high performance battery is expected. Use innovative design of carbon conductive network via proper synthesis process to invent LiFePO4 battery, which with both high electric capacity and high energy density, would be the research trend in academic field. In this paper we show that main path analysis is a proper methodology for finding influence articles and authors in the field of technology research.
