基于CiteSpace的锂离子动力电池在我国新能源汽车产业的研究热点与趋势分析

Research Hotspot and Trend Analysis of CiteSpace Based Lithium-ion Power Battery in China's New Energy Automobile Industry

基于CiteSpace知识图谱视角,通过选取2010-2022年间在中国知网(CNKI)中收录的动力锂离子电池文献为样本,综合采用文献计量学和可视化技术,分析国内动力锂离子电池领域的研究现状、合作关系、研究热点及前沿趋势。研究表明:研究热点主要是锂矿资源、磷酸铁锂、荷电状态、健康状态、电池管理系统等方面,研究前沿趋势主要是剩余使用寿命、混合储能系统、退役动力、充电策略等方面。

Based on the perspective of CiteSpace knowledge Graph,the literature on power lithium-ion batteries collected in CNKI during 2010-2022 was selected as samples,and the literature metrology and visualization techniques were comprehensively used to analyze the research status,cooperation,research hotspots and frontier trends in the field of power lithium-ion batteries in China.The research showed that the research hotspots were mainly lithium ore resources,lithium iron phosphate,charge state,health state,battery management system,etc,and the research frontier trends were mainly remaining service life,hybrid energy storage system,decommissioning power,charging strategy,etc.
