[Purpose/significance] In order to discover the dynamic characteristic of authors' research interests, this paper puts forward a research framework based on life cycle theory and Author-Topic(AT) model. [Method/process] The research collects literatures of Lithium Ion Battery from CNKI database and discribes the disciplinary field life cycle by literature information growth rule. Author-Topic distribution, Topic-Word distribution, Document-Topic distribution ware extracted by AT model. Topical and research interests evolutionary analysis were achieved by tracking the topic trends and authors's research interests in different lify cycle stage-slices. [Result/conclusion] The experimental results by running in the collections of 5508 CNKI literatures show that the research interests of core authors become biggest in growth stage of Lithium Ion Battery, which proves that these core authors really promote the development of discipline. Genarally speaking, the core author whose research interests evolutionary trend agrees with topic evolutionary trend, could lead to the development of this topic. But, there are still some topics, whose evolutionary trend is not affected by core authors. Usually, these topics have bigger topic intensity and contaion more widely research directions.
