After removal of mercury in the silver oxide batteries with the distillation process, the leaching of valuable metals from the residue was studied. The distilled residue was reacted with the various HNO, concentration, reactlon temperature, readion time and pulp density. It was found that the optimum condition for leachmg was 2N HNO,, 40-60% reaction temperature, 6 hours reaction tlme and 10g/200ml pulp density. More than 99% of silver and zinc were dissolved in this process while less than 50% of iron and nickel were leached

There are several kinds of battery such as zinc-air battery, lithium battery, Manganese dry battery, silver oxide battery, mercury battery, sodium-sulphur battery, lead battery, nickel-hydrogen 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 on the recycling technologies of the used lithium battery were analyzed. The range of search was limited in the open patents of USA(US), European Union(EP), Japan(JP), and Korea(KR) from 1986 to 2006. Patents were collected using key-words searching and filtered by filtering criteria. The trends of the patents was analyzed by the years, countries, companies, and technologies.

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.

아연-산화은 전지는 높은 에너지 및 전력밀도를 가지고 있으나 비싼 제작비용 때문에 우주항공, 군사무기 등 특수한 분야에서 주로 이용되며, 특히 전해액이 별도의 용기에 보관되어 있다가 외부 신호에 의해 충전된 dry상태의 전지에 주입되어 활성화되는 1차 또는 비축형 아연산화은 전지는 우수한 고율방전 특성, 장시간의 저장기간 및 활성화와 동시에 부하를 인가 할 수 있는 특성 때문에 많은 무기체계에서 이용하고 있다. 이러한 아연-산화은 전지의 아연전극은 높은 다공도와 반응 면적을 가져야 하며, 특히 방전중 아연전극의 전위는 가역 수소전위 보다 더 음전위이기 때문에 수소가스가 다량 발생하게 되므로 수은과 같은 높은 과전압을 갖는 물질을 첨가하여 가스 발생량을 줄이고 부동태화(passivation)를 억제하게 된다. 그러나 국내 여건상 수은을 사용하여 전지를 제작하는 것은 환경문제 등으로 인하여 어렵기 때문에 본 연구에서는 수은을 사용하지 않고 비축형 아연-산화은 전지의 음극판을 제작하기 위하여 전착법(electro deposit)과 mesh 제작방법을 혼합하여 아연전극을 제작하였으며, 기판에 석출된 아연과 아연 mesh의 질량비율에 따른 전지의 성능을 평가하였다.
