The difference between alkaline batteries and carbon batteries is mainly in the following aspects:
Materials: Alkaline batteries are mainly composed of metal and alkaline electrolyte, such as zinc and manganese dioxide, so the energy density is high. Carbon batteries are mainly composed of graphite and acidic electrolyte, such as graphite and zinc chloride, so the energy density is low.
Voltage: The voltage of alkaline battery is usually higher than that of carbon battery, because the electrolyte in alkaline battery can provide more ions, thus generating higher voltage.
Environmental protection: alkaline batteries generally do not contain heavy metal ions, so they release less current, so they are more environmentally friendly. Carbon batteries contain heavy metals such as cadmium, which must be recycled, otherwise it will pollute the environment.
Weight: Alkaline batteries are usually heavier than carbon batteries because they contain more metallic materials.
Performance: Alkaline batteries usually have larger capacity than carbon batteries because of their higher energy density. In addition, alkaline batteries release more current, which is suitable for electrical appliances that need more current.
Generally speaking, there are obvious differences between alkaline batteries and carbon batteries in terms of materials, voltage, environmental protection, weight and performance. Choosing which type of battery to use depends on the specific application requirements and environmental conditions.
