摘　　要：基于Web of Science核心数据库对锂二次电池相关文献进行Cite Space可视化图谱分析。得到锂二次电池研究可分为3个阶段:起步阶段、平稳增长阶段和快速增长阶段。研究的主要力量主要集中在日本、美国、中国、法国和韩国,越来越多的国家参与到研究中来,国家之间合作日益密切。以合成具有高能量密度高安全性能的电池材料为目的,探寻新型电极材料以及利用新型技术进行对锂二次电池进行结构和性能优化是研究的热点。最后总结指出目前研究较多的是层状锂的氧化物材料、尖晶石材料和聚阴离子材料,碳、硅等负极材料和固态电解质,对正极掺杂元素的选择与优化,结合纳米等新技术和高性能的新型材料是锂二次电池重要的发展方向。Based on the core collection database of Web of Science,the research about lithium secondary batteries was visually analyzed by the software Cite Space.The results showed that the research history of lithium secondary batteries can be divided into three stages,namely,the initial,steady growth,and rapid growth stages.The main research force changed constantly in Japan,the USA,China,France,and South Korea.More countries are joining this research,and countries are collaborating more closely.For the synthesis of battery materials with a high energy density and safety performance,the exploration of new electrode materials and technologies for structural performance optimization is an important research topic.The studies on electrodes for lithium secondary batteries are focused on layered oxides,spinel,and polyanionic materials for cathodes,and carbon,silicon for anodes and solid-state electrolyte.The selection of positive-electrode doping elements,the combination of novel technologies(such as nanometer and porous,among others),and emerging highperformance materials are important development directions for lithium secondary batteries.
