<要旨>
二次電池のケーススタディを通して,引用分析とエキスパートによる考察から,学術論文と特許の差分を分析する方法論を提案する.学術論文は基礎的,特許は応用的になる傾向があった.学術論文と特許それぞれの主要5領域が扱うトピックを比較すると,リチウム二次電池と電解質に関する2組の対応関係が見られ,トピックスの内容や平均出版年から学術論文と特許の差分を抽出した.その結果,産業化の可能性がある領域が発見された.
<Abstract>
In this paper, we perform a case study of secondary batteries research and technology to develop a method of detecting gaps between science and technology via a combination of citation-and expert-based approaches. Scientific research tended to be basic, whereas patents focused on applied technology developed from the basic research. Of five science research fronts and five areas of technology, three scientific groups, Li (Mn, Co, Ni) 0-, Li-Sn-and olivine-based batteries, corresponded to the largest set of patents relating to Li. These three academic outcomes are so recently published that these can be the candidates for industrial opportunities. Other than Li, the largest set of academic papers correlated semantically to the third largest set of patents. Although patents aimed physically such as covering the electrolytes more strictly, scientific researches aimed to polymerize the electrolytes used for secondary batteries, while. There also exists an opportunity for polymer electrolytes to solve the problems relating to electrolytes. Our results offer an intellectual basis for detecting possible opportunities for industry.
