What is a carbon based battery?

1： What is a carbon based battery

Carbon based batteries, also known as our common "neutral zinc manganese dioxide dry batteries," are primary batteries in chemical batteries and are also disposable batteries. Because the electrolyte of the dry battery power supply device is a paste that cannot be moved, it is also known as "dry batteries.".

Carbon based batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also widely used in various aspects of the national economy, such as national defense, scientific research, communications, navigation, aviation, medicine, etc. Carbon batteries are used in low consumption electronic products such as clocks and wireless mice. High power electronic devices, such as cameras, require alkaline batteries. Some cameras are not alkaline, so nickel hydride is used.

2： Characteristics of carbon battery

Carbon battery is a relatively common dry battery, which is not only cheap, but also safe to use. It has been used for large capacity discharge and long-term work. Due to the small internal resistance of its battery, its current is larger than that of ordinary zinc manganese dioxide batteries.

The disadvantage of carbon batteries is that they are disposable and cannot be recycled. The second reason is that carbon batteries do not use the camera for a long time, and they cannot be placed in the phone because over time, corrosive liquid can flow out of the battery. If it flows into the camera, it may cause damage to the camera.

3： Classification of carbon batteries

According to the different structures and principles of carbon batteries, they can be divided into paste type zinc manganese carbon batteries, cardboard type zinc manganese carbon batteries, thin film type zinc manganese dry batteries, and so on. The common types of carbon batteries in our daily life are No. 5, No. 7, No. 1, etc.

Regardless of the type of carbon battery, its cathode material is generally MnO2, graphite rod; The negative electrode material is zinc sheet, but the electrolyte in it is different, generally including NH4Cl, ZnCl2, and starch paste.
