Using spent alkaline Zn-Mn batteries as resource materials through dissolving with nitric acid,Mn-Zn ferrite powders with cubic spinel structure were directly synthesized by sol-gel method.

The characteristics of Zn of spent alkaline Zn-Mn batteries and its suitable conditions dissolved in nitric acid were studied.

Using spent alkaline Zn-Mn batteries as resource materials via dissolving with nitric acid, a series of Cu doped Mn-Zn ferrites(Mn0.

The status quo of recycle technology of spent battery;

Study on waste battery treatment by sinter;

The study showed that tadpoles of Bufo Melanosticus,a specie widely distributed in South China,are highly sensitive to waste battery leaching and that the median lethal concentration decreases with the increase of time.

It expounds the consumption,classification,disadvantages and recycle of the waste battery in China.

In regard to physical volume and weight,waste batteries are trifle in the living garbage,but directly abandoning them in the nature after usage without any treatmen will result in the seriours pollution of the environment.

With the development of battery industry,the recycling of waste batteries has been of great importance in terms of resource recycling,environment protection and human health.

In this article, treatment and disposal of all different waste batteries in domestic and foreign countries has been introduced.

Acid-leaching method was used to recover zinc resource in the cathode substance of waste alkaline dry battery.
