Abstract

The invention discloses a recycle processing method of a waste nickel-hydride power battery. The recycle processing method comprises the following steps of cutting a shell after the waste nickel-hydride power battery to be processed is cut, and reserving a single battery; smashing the single battery, and smashing a metal-containing collection substance with relatively large particles to relatively small and highly-dispersed crushed aggregates; performing magnetic separation after drying the smashed crushed aggregates, separating the crushed aggregates to two parts of metal-containing crushed aggregates and a binding agent / fiber substance by means of magnetism of an electrode material; cleaning the separated binding agent and the fiber substance; and drying and ball-grinding the separated metal-containing crushed aggregates to obtain fine particle crushed aggregates, performing wet immersion on the fine particle crushed aggregates, and extracting a rare-earth element or a compound. By the method, the harm of the waste nickel-hydride power battery to an ecological environment can be reduced, and the recycle rate of resources is effectively improved.

Description

technical field [0001] The invention relates to the technical field of new energy power batteries, in particular to a method for recycling waste nickel-metal hydride power batteries. Background technique [0002] At present, nickel-metal hydride batteries are secondary batteries, which belong to the scope of national key development of clean energy support, especially for hybrid vehicles, which are the most widely used nickel-hydrogen batteries in the world. Field Guide", "The Twelfth Five-Year Plan" National Strategic Emerging Industry Development Plan issued in 2012, and "Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)" are all key support objects. Ni-MH batteries have many excellent characteristics such as no pollution, high performance, high power, fast charging and discharging, and durability. Compared with lead-acid batteries, nickel-metal hydride batteries have the characteristics of high specific energy, light weight, small volume, a...
