Carbon battery structure: inside: manganese dioxide and carbon powder mixed with ammonium chloride, paper dipped in ammonia chloride, carbon rod (using conductive graphite), insulator outside: copper cap (positive electrode), zinc plate (negative electrode) ), packaging plastic carbon battery structure principle: 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. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
