Principle of Carbon Battery Structure Zinc-manganese dry battery is a dry battery commonly used in daily life. Cathode material: MnO2, graphite rod Anode material: zinc sheet Electrolyte: NH4Cl, ZnCl2 and starch paste The battery symbol can be expressed as (-) Zn|ZnCl2, NH4Cl (paste) ‖ MnO2|C (graphite) (+) negative electrode ：Znu003dZn2++2e Positive electrode: 2MnO2+2NH4++2eu003dMn2O3+2NH3+H2O The total reaction: Zn+2MnO2+2NH4+u003d2Zn2++Mn2O3+2NH3+H2O The electromotive force of zinc-manganese carbon battery is 1.5V. The emergence of NH3 gas is adsorbed by MnO2, causing the electromotive force to drop rapidly. If the high-conductivity paste KOH is used instead of NH4Cl, and the cathode material is changed to a steel cylinder, the MnO2 layer is close to the steel cylinder, which constitutes an alkaline zinc-manganese dry battery. Due to the battery reaction, there is no gas, and the internal resistance is low. ,relatively stable. Carbon storage battery belongs to the original storage battery in chemical power supply. It is a kind of disposable storage battery. It uses manganese dioxide as the positive electrode and zinc cylinder as the negative electrode to convert chemical energy into electrical energy to supply an external circuit. In the chemical reaction, because zinc is more active than manganese, zinc loses electrons and is oxidized, while manganese gets electrons and is reduced.
