Abstract

In Korea, a good recycled product (GR) certification system was introduced in 1997 to improve resource and energy use efficiency. However, in industry and society, recycled products are not used well because of the lack of awareness of recycled materials. In this study, the status of domestic and international quality standards for nickel materials was investigated, and the purity and electrochemical properties of nickel sulfate prepared from ore and nickel sulfate recovered from waste lithium-ion batteries were evaluated during the electroplating process. As a result of the test, it was found that there is no quality difference between recycled nickel sulfate and high-purity nickel sulfate reagents when used in the electroplating industry.

국내에서는 1997년 우수 재활용제품(good recycled product, GR) 인증 제도를 도입하여 자원과 에너지 사용효율 개선을 증진하고 있으나 산업계 및 사회 전반적으로 재활용 소재에 대한 인식 부족으로 인해 재활용 제품 사용이 잘되지 않고 있다. 따라서 본 연구에서는 니켈 소재의 국내·외 품질 기준 현황을 조사하였고, 광석으로부터 제조된 황산니켈과 폐리튬이온전지로부터 재소재화 된 황산니켈에 대하여 전해도금 공정에서의 순도 및 전기화학적 특성을 평가하였다. 평가 결과, 전해도금 산업에서 사용 시 재활용 황산니켈과 고순도 황산니켈 시약의 품질은 차이가 없는 것으로 판단된다.
