Is the zinc fierce battery be eliminated?

　　Zinc and manganese batteries are the original battery with manganese dioxide as the positive electrode, zinc as the negative electrode, and ammonium chloride aquatic solution as the main electrolyte. Commonly known as dry battery. In the academic world, it is also called Leklang Xie Dian.

　　Zinc Batteries are mainly: neutral zinc fierce batteries and base manganese batteries.

　　Neutral zinc -manganese batteries: suitable for small and medium -current intermittent electricity, exported to Africa and the Middle East;

　　Alkaline manganese battery: high capacity, good low temperature performance, can be discharged continuously at large currents. Exit Europe, America and Japan;

　　The development of zinc fierce battery: In 1868, French telecommunications engineer Leclanche led 20%NH4C1 as an electrolyte

　　The Zn-MNO2 battery came out.

　　1923: Acetylene black replaces graphite (acetylene black has good hygroscopic and liquid protection, which increases the battery capacity by 40%to 50%).

　　1945: Electrolytic MNO2 instead of natural MNO2.

　　1950: Alkaline zinc -manganese battery (it uses KOH with good conductivity, while using electrolytic MNO2, the battery performance is greatly improved)

　　In the 1960s: Born in cardboard batteries.

　　In the 1970s: The advent of Holchrium chloride batteries in the 1980s: Alkaline zinc and manganese can be used to charge batteries, with a loop of 30 ~ 50 times.

　　The performance of zinc and manganese battery complies with national industry standards, which is equivalent to foreign battery performance. Due to capable loads, large current discharge, large electrical capacity, good low temperature performance and leakage resistance, performance price ratio is high (2-3 times the price of dry batteries, large current working electricity is 6-8 times the advantages and are widely used for civilian use for civilian use. And Industry. Special applicable to flash camera, micro -inclusion machine, camera, intercom, BP machine, shaver, palm -type color video and game machines, toys, remote test, alarm, calculator, hearing aid, flashlight and electric clock and other instruments and equipment . For example, the AA (No. 5) alkaline zinc-manganese battery can be taken in a flash camera for 8-10 rubber rolls, while the dry battery can only take 1-2 rubber rolls, and cadmium nickel batteries cannot be used. It can be said that it is used in dry batteries. Cadmium nickel batteries can be replaced by alkaline zinc -manganese batteries.

　　Zinc and manganese batteries are mainly caused by about more than a dozen raw materials such as zinc, manganese, mercury, copper, iron, plastic, carbon and acidic electrolyte solution, etc. It is harmful to the hazards of dry manganese dry batteries. Waiting for electrolyte solutions may enter the environment after abandonment.
