Chemical composition, internal materials, performance characteristics and application scenarios.

1. The chemical composition and internal materials are different. The positive electrode of carbon batteries is usually composed of carbon rods and manganese dioxide, while the negative electrode is zinc skin. The positive electrode of alkaline batteries is also manganese dioxide, but its The negative electrode is zinc powder, and an aqueous solution of potassium hydroxide is usually used as the electrolyte.

2. Performance characteristics. The voltage of carbon batteries is about 1.5 volts, which is suitable for low-power devices, such as remote controls, clocks, etc. The voltage of alkaline batteries is also about 1.5 volts, but the capacity is higher. Large, suitable for high power consumption equipment such as flashlights and power tools.

3. Application scenarios: Carbon batteries are suitable for electrical appliances with low current and low power, while alkaline batteries are suitable for electrical appliances that require higher current and longer discharge time.
