Feasibility study for the recycling of nickel metal hydride electric vehicle batteries. Final report.

摘要

This feasibility study examined three possible recycling processes for two compositions (AB(sub 2) and AB(sub 5)) of nickel metal hydride electric vehicle batteries to determine possible rotes for recovering battery materials. Analysts examined the processes, estimated the costs for capital equipment and operation, and estimated the value of the reclaimed material. They examined the following three processes: (1) a chemical process that leached battery powders using hydrochloric acid, (2) a pyrometallurical process, and (3) a physical separation/chemical process. The economic analysis revealed that the physical separation/chemical process generated the most revenue.
