In spent battery materials, there exist plenty of valuable metals, such as nickel, cobalt and rare earth element. The recovery of valuable metals from them not only protects the environment, but also improves the utilization of resources and lowers the cost of battery production. Similarly to many other batteries, random dumping of spent nickel-hydrogen batteries would lead to serious pollution; the recovery of valuable metals from them is of great significance. A review on recycling of spent nickel-hydrogen batteries was presented in the present paper, and several recovery technologies were introduced in detail. In addition, the prospect on comprehensive recovery of valuable metals from spent electrode materials of nickel-hydrogen batteries was made.
