7.Internal structure:

8.Chemical reaction:

In a zinc–manganese dioxide dry battery, the zinc can is the negative terminal through which the electric current flows into the device. The zinc is oxidised according to the following half-equation.

Zn(s) → Zn2+(aq) + 2 e− [E° = -0.7626 volts]

The positive terminal is a mixture of chemicals – usually a mixture of manganese dioxide powder, carbon and an electrolyte to increase the electrical conductivity. A carbon electrode rod also is placed inside the middle of the battery, connecting the two metal-capped ends of opposite charge and serving as the positive terminal.The reaction is as follows:

2MnO2(s) + 2 e− + 2NH4Cl(aq) → Mn2O3(s) + 2NH3(aq) + H2O(aq) + 2 Cl− [e° ≈ +.5 v]

and the Cl− combines with the Zn2+.

There are other possible side-reactions, but the overall reaction in a zinc–manganese dioxide battery can be represented as:

Zn(s) + 2MnO2(s) + 2NH4Cl(aq) → Mn2O3(s) + Zn(NH3)2Cl2 (aq) + H2O(l)

9.Product procedure:

1	Zinc can	The zinc can is the negative terminal and anode material
2	Inserting the separator	The separator and the bottom paper are inserted to prevent battery short-circuit between the positive and the negative electrode.
3	Filling cathode material	The mixture of manganese dioxide, electrolyte and others are filled as the cathode material
4	Inserting carbon rod	The carbon rod for collecting electricity is inserted into the middle of the battery
5	Sealing	The plastic gasket for sealing is fitted to prevent leakage and water evaporation
6	Fitting tinplate bottom and PVC jacket	The tinplate bottom is placed on the bottom of zinc can and PVC jacket is shrinked
7	Finished product	The batteries are packed by shrink after inspecting the voltage, current and appearance
