6.Internal structure:

7.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)

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:
