What Is a Zinc-Carbon Battery?

Carbon battery full name: neutral zinc-manganese dry battery (zinc-manganese dry battery), which is a primary battery in chemical power, is a disposable battery.

With the development of science and technology, carbon batteries have developed into a large family, and there have been many types so far. Common are common zinc-manganese dry batteries.

For the most commonly used zinc-manganese carbon batteries, they can be divided due to different structures: paste zinc-manganese carbon batteries, cardboard zinc-manganese carbon batteries

Common models: No. 5 (AA or R6) No. 7 (AAA or R03) No. 1 (R20)

internal:

The full name of the carbon battery should be a carbon zinc battery (because it generally has a positive electrode with a carbon rod and a negative electrode with a zinc skin), also known as

Zinc-manganese dry batteries are 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

(1) Check whether the electrical and battery contacts are clean, wipe them with a damp cloth if necessary, and load them with the correct polarity after drying;

(2) Do not mix new and old batteries, and you cannot mix batteries of the same type but different types;

(3) Prohibit heating, charging or other methods to regenerate the primary battery; disassembly of the battery is prohibited

(4) It is forbidden to short-circuit the battery. Beware of infants playing with the battery, especially to prevent infants from swallowing the button battery.

(5) The switch should be cut off after use, and the battery should be removed after long-term use. ^[2]

The difference between alkaline batteries and carbon batteries:

1. Alkaline batteries have 4-7 times the capacity of carbon batteries, and their prices are 1.5-2 times that of carbon batteries.

2. Carbon batteries are suitable for low-current appliances, such as quartz clocks and remote controllers; alkaline batteries are suitable for high-current appliances, such as digital cameras, toys, shavers, wireless mice, etc.

3. The full name of carbon battery should be carbon-zinc battery (because it is generally a positive rod with a carbon rod and a negative electrode with zinc skin), also known as a zinc-manganese battery. It is the most common dry battery. It has a low price and is safe and reliable to use. Features, based on environmental considerations, because they still contain cadmium, they must be recycled to avoid damage to the global environment.

Alkaline batteries are suitable for large discharge and long-term use. The internal resistance of the battery is low, so the current generated is larger than that of ordinary zinc-manganese batteries. The electrical conductivity is a copper rod, and the outer case is a steel case. Because of its environmental protection and high current characteristics, alkaline batteries use more.

4. Leakage: Since the outer shell of a carbon battery is a zinc cylinder that acts as a negative electrode, it must participate in the battery's chemical reaction, so it must leak over a long time, and leak in a few months if the quality is not good; alkaline batteries The casing is steel and does not participate in chemical reactions, so alkaline batteries rarely leak, and the shelf life is more than 5 years. ^[3]
