Therefore, We think CNB-16 is promising to be a substitute for mercury in zinc-manganese dry cells.

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.

Current treatment situation & technology as well as countermeasures of the waste dry battery in our country;

Recycling and integrated utilization of waste dry battery——Integrated chemical experiments including green,environmental protection and ability training;

The zinc of waste dry battery is used to deoxidize the high value manganese into Mn~(2+).
