Title: Recycling of nickel-metal hydride battery scrap

Abstract

Nickel-metal hydride (Ni-MH) battery technology is being developed as a NiCd replacement for applications in consumer cells and electric vehicle batteries. The U.S. Bureau of Mines is investigating hydrometallurgical recycling technology that separates and recovers individual components from Ni-MH battery scrap. Acid dissolution and metal recovery techniques such as precipitation and solvent extraction produced purified products of rare-earths, nickel, and other metals associated with AB{sub 2} and AB{sub 5} Ni-MH scrap. Tests were conducted on scrap cells of a single chemistry that had been de-canned to reduce iron content. Although recovery techniques have been identified in principal, their applicability to mixed battery waste stream and economic attractiveness remain to be demonstrated. 14 refs.
