The difference between R6 carbon battery and alkaline battery
First, both carbon batteries and alkaline batteries are dry batteries, but they are divided into two types according to their materials.
2. The full name of carbon battery should be carbon-zinc battery (because its positive electrode is generally carbon rod, and its negative electrode is zinc skin), also known as zinc-manganese battery, which is the most common dry battery at present. It has the characteristics of low price, safe and reliable use. Since carbon batteries contain the heavy metal cadmium, they must be recycled to avoid damage to the Earth's environment. (So we generally use carbon rods as positive electrodes and galvanized batteries as negative electrodes for recycling).
3. Alkaline batteries, also known as alkaline dry batteries or alkaline zinc-manganese dry batteries, are suitable for instruments that require long-term discharge. The internal resistance of alkaline batteries is low, so the current generated is larger than that of ordinary zinc-manganese batteries, and the mercury content of environmentally friendly alkaline batteries is only 0.025%, which does not need to be recycled. Based on the environmental protection and high current characteristics of alkaline batteries, there are more alkaline batteries in use now.
Fourth, the nominal voltage of both carbon batteries and alkaline batteries is 1.5V, but alkaline batteries of the same size have a larger capacity and are more suitable for high-current discharge.
Fifth, the essential difference between carbon batteries and alkaline batteries lies in the difference in internal materials. In short, carbon batteries are composed of carbon rods and zinc skins, but there are cadmium and mercury in them, which is not conducive to environmental protection. But it is cheap, so it still has a place in the market, and alkaline batteries do not contain heavy metal ions, and have high current, which is conducive to environmental protection. It is the direction of future battery development!
Sixth, the power of alkaline batteries is 4-5 times that of carbon batteries, and the price is 1.5-2 times that of carbon batteries. Carbon batteries are suitable for small current electrical appliances, such as quartz clocks, remote controls, radios, etc. Alkaline batteries are suitable for high-current electrical appliances, such as BP players, CD players, electric toothbrushes, electric toys, and handheld computers.
