The difference between alkaline batteries and carbon batteries

Jun 18,2024
Alkaline batteries and carbon batteries are two common types of batteries, which are different in terms of use, power, and environmental protection. Here are their main differences:
1. Different uses
The use of carbon batteries and alkaline batteries is completely different. Carbon batteries are generally used in devices with relatively small current requirements, such as flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, electronic toys, scientific research, telecommunications, navigation, aviation, medicine and other fields. Alkaline batteries are suitable for instruments that require large discharge and long-term use, such as flashlights, razors, electric toys, CD players, high-power remote controls, wireless mice, keyboards and other daily necessities.
2. Different power
From the basic power point of view, alkaline batteries are more cost-effective than carbon batteries. The capacity of an alkaline battery decreases as the output current increases. For example, the same battery can have a capacity of 3000mAh at low output current, but when used in a load with 1A current, the capacity is only 700mAh, less than 1/4 of the original capacity.
3. Different degree of environmental protection
There is also a name for alkaline batteries: alkaline dry batteries or alkaline zinc-manganese dry batteries. The internal resistance of alkaline batteries is lower than that of carbon batteries, while environmentally friendly alkaline batteries contain only 0.025 percent mercury and do not need to be recycled. Therefore, alkaline batteries are much more environmentally friendly than carbon batteries. The full name of carbon battery is carbon zinc battery. Generally, the positive electrode is carbon rod and the negative electrode is zinc skin, also known as zinc manganese battery. Zinc manganese battery is a common dry battery, it has the characteristics of low price and safe and reliable use, but because the carbon battery contains heavy metal cadmium, it must be recycled.
4. The battery structure and working principle are different
Alkaline batteries are generally composed of three poles, one of which is a nickel-hydrogen reaction pole, and the other two poles are copper and manganese; while carbon batteries generally have two poles, one of which is activated carbon and the other is extremely alkaline. Alkaline batteries generate electrical energy through the nickel-hydrogen reaction principle; while carbon batteries generate electrical energy through the hydrocarbon reaction principle. In addition, the voltage of an alkaline battery is generally 1.2V, while the voltage of a carbon battery is generally 1.5V.
5. Life and safety are different
The service life of alkaline batteries is generally shorter than that of carbon batteries, but alkaline batteries are safer because they are not easy to heat or explode, but carbon batteries are more dangerous because they are easy to heat and explode. In addition, Nanfu Battery, an outstanding representative of alkaline batteries, as an advanced battery technology company in China, focuses on the field of small batteries, insisting on taking science and technology as the forerunner, product as the center of gravity, and customer as the center. It has a technical center and a post-doctoral research station, and has established a number of new energy research centers in cooperation with national key universities and the Institute of Chinese Academy of Sciences, forming a scientific research and innovation mechanism. It is an enterprise with strong scientific and technological strength in the battery field in China. Committed to providing users with technology and experience of power products and services.
