从镍氢电池废弃负极材料中综合回收有价金属的研究综述(英文)

Review on Comprehensive Recovery of Valuable Metals from Spent Electrode Materials of Nickel-Hydrogen Batteries

在废电池中含有大量有价金属,如镍、钴、稀土元素等。从废电池材料中回收有价金属不仅能保护环境,还能利用资源并能降低电池生产成本。与其他电池类似,任意丢弃废镍氢电池将导致严重污染,因而从废弃镍氢电池中回收有价金属的意义重大。本文综述了废弃镍氢电池回收问题,并详细介绍了几种回收技术。此外,展望了从镍氢电池废弃电极材料中综合回收有价金属的前景。

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.
