Abstract

The rapid demand for electric vehicles and energy storage systems has increased interest in energy storage devices worldwide. New technological alternatives are needed to reliably supply energy storage mineral resources such as lithium and vanadium, which are key materials for energy storage devices. Already, research and development activities are taking place in various countries on technologies that can directly secure lithium and vanadium. Accordingly, it is very important to analyze each country's technological trends through patent and paper analysis to establish effective research and development strategies and to set future technological development directions. This study analyzed trends in the development of new technologies and the current status of research and development at home and abroad through patent data from Korea, the United States, Europe, and Japan that were disclosed or registered from 1970 to October 2019, and the data searched for papers from January 2000 to October 2019. According to the analysis, the current growth stage of the technology related to energy storage minerals is in the beginning stage. Therefore, it is believed that a strategy to rapidly upgrade technology by combining the development of new technologies and demonstration of developed technologies is needed in order to lead the technology market and strengthen the competitiveness of technologies.

전기차, 에너지저장시스템의 수요급증으로 에너지 저장장치에 대한 관심이 세계적으로 증가해 왔다. 에너지 저장장치의 핵심원료인 리튬과 바나듐 등과 같은 에너지저장광물 자원을 안정적으로 공급하기 위하여 새로운 기술적 대안이 필요하다. 이미 리튬과 바나듐을 직접 확보할 수 있는 기술에 대한 여러 국가들의 연구개발 활동이 이루어지고 있다. 이에 따라 효과적인 연구개발 전략을 수립하기 위해서 특허 및 논문 분석을 통해 각 국의 기술동향을 분석하고 향후 기술발전방향을 설정하는 것이 중요하다. 본 연구는 1970년부터 2019년 10월까지 출원 공개 또는 출원 등록된 한국, 미국, 유럽, 일본의 특허자료와 2000년 1월부터 2019년 10월까지의 논문을 대상 검색된 자료를 통해 신기술 개발동향 및 국내외 연구개발 현황을 분석하였다. 분석결과, 현재 에너지저장광물과 관련된 기술의 성장단계는 태동기 단계에 있는 것으로 분석되었다. 따라서 기술시장 선도와 기술 경쟁력 강화를 위해 새로운 기술의 개발과 개발된 기술에 대한 실증을 병행하여 빠르게 기술을 고도화 하는 전략이 필요하다고 사료된다.
