At present, many people are confused what is the battery, and the battery is made ​​of how dry the structural principle.

Today, the company took your questions to learn together what is dry?

Current disposable batteries in the most representative of the manganese dioxide battery, known batteries. This disposable batteries, is essentially a first Leclanche (G.Leclan-Chel868 years) battery improvements made.

Manganese dioxide batteries or Leclanche battery chemistry reaction equation: Zn +2 Mn02 +2 NH4Cl == Zn (NH3) 2Cl2 + Mn203 + H2o
The structure of manganese dioxide batteries as shown below:

Case Round zinc cylinder is the cathode, zinc cylinder filled with electrolyte, the electrolyte soaked paper or with a paste of ammonium chloride ammonium chloride is made.
The middle of the battery anode carbon rod, carbon rod is surrounded depolarizer.
Depolarizer electromotive force is reduced to prevent drug, usually by manganese oxide Toner (plus toner is to increase the conductivity of manganese dioxide) and ammonium chloride (NH4Cl) is made. We already know that the graphics and text according to the above analysis we should know what is dry, then there is now common ordinary zinc-manganese dry cell batteries (abbreviated carbon batteries), alkaline manganese batteries (abbreviated alkaline batteries), magnesium - manganese battery, zinc - air batteries, zinc - mercury oxide batteries, zinc - silver oxide batteries, lithium - manganese batteries. Wherein the carbon-zinc batteries and alkaline batteries are more common in our daily lives, but also the most affordable prices the most widely used batteries.
