Abstract
전지는 공기아연리튬망간산화은나트륨-유황납축니켈-수소 이차니켈-카드뮴리튬이온알칼라인 전지 등의 여러 종류가 있다. 경제적, 효율적 관점에서 폐전지의 재활용 기술은 폭넓게 연구되어 왔다. 본 연구에서는 폐전지의 재활용 기술에 대한 특허와 논문을 분석하였다. 분석범위는 1972년~2011년까지의 미국, EU, 일본, 한국의 등록/개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였고, 기술의 정의에 의해 필터링하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술에 따라 분석하여 나타내었다. There are several kinds of batteries such as zinc-air battery, lithium battery, Manganese dry battery, silver oxide battery, sodium-sulphur battery, lead acid battery, metal hydride secondary battery, nickel-cadmium battery, lithium ion battery, alkaline battery, etc. These days it has been widely studied for the recycling technologies of the used battery from view points of economy and efficiency. In this paper, patents and published papers on the recycling technologies of the used battery were analyzed. The range of search was limited in the open patents of USA (US), European Union (EU), Japan (JP), Korea (KR) and SCI journal articles from 1972 to 2011. Patents and journal articles were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journal articles were analyzed by the years, countries, companies, and technologies.
