为深入了解并跟踪锂硫电池正极发展动态,以 Web of Science 为数据源,采用可视化软件 CiteSpace,从年发文量、作者、研究地域、研究机构、研究热点等方面对锂硫电池正极领域进行可视化文献分析,并绘制相应的知识图谱.基于大量文献调研分析,得到如下结论:(1)锂硫电池正极研究经历 1978-2009 年、2010-2013 年和 2014-2021 年三个阶段,该领域的研究在世界范围内正受到极大关注,并且在未来几年仍属于热门研究方向;(2)锂硫电池正极属于多学科交叉领域,中国在该领域深耕多年,形成一批具有较高学术影响力的研究机构和学者,已成为该领域的核心主导力量;(3)未来有关锂硫电池正极的研究主要集中在复合型正极的构建、特殊形貌(如核壳形貌)的设计、材料改性新技术(如原子层沉积)的开发等方面,并努力实现锂硫电池正极倍率性能和面容量的大幅提升.
The Research Status and Trend of Lithium-sulfur Battery Cathodes
To grasp the research status of lithium-sulfur battery cathodes,CiteSpace visualized software was employed to analyze the published documents on lithium-sulfur battery cathodes from the perspective of annual publications,authors,research regions,research institutions and research highlights by using Web of Science as the database,and the corresponding knowledge map was drawn.According to the investigation and analysis of a large amount of documents,the following conclusions can be reached:(1)The development of lithium-sulfur battery cathodes experiences three different stages(from 1978 to 2009,from 2010 to 2013 and from 2014 to 2021).The related research is attracting worldwide attentions and will become the hot direction in the next few years.(2)The research on lithium-sulfur battery cathodes belongs to multidisciplinary direction.China has been investigating this field for a long time and cultivated a group of research institutions and scholars with high academic impact,thus determining its leading role in this field.(3)The future research on lithium-sulfur battery cathodes mostly focuses on the construction of hybrid cathode,design of special morphology(such as core-shell structure),new material modification technology(such as atomic layer deposition)and so on,and is striving to greatly promote the rate performance and areal capacity of lithium-sulfur battery cathodes.
