Zinc Carbon Battery is the disposable zinc-manganese dry battery, usually, we also call heavy-duty battery. In daily life, the most used models are R03/AAA, R6/AA, R14/C, R20/D, 6F22/9V, and 4R25.

–A Brief Description of Zinc-Carbon Batteries)
The zinc-carbon battery frequently referred to as a heavy-duty, extra-heavy-duty, or even super-heavy-duty battery, is an improvement on the original zinc-carbon battery, using purer chemicals and giving a longer service life and steadier voltage output as it is used and offering about twice the service life of general.
The Zinc carbon battery is packaged in a zinc can that serves as both a container and anode. It was developed from the wet “Super” or “Heavy Duty” batteries, technically called zinc chloride cells, are an improved version from the cheaper “General Purpose” variety. The cathode is a mixture of manganese dioxide and carbon powder. The electrolyte is a paste of zinc chloride and ammonium chloride dissolved in water.
Zinc carbon batteries are the least expensive primary batteries and thus a popular choice by manufacturers when devices are sold with batteries included. They can be used in remote controls, flashlights, toys, or transistor radios, where the power drain is not too heavy.
Through continuous technical improvement, our carbon batteries are environmentally friendly, do not contain mercury and lead, and comply with the EU’s ROHS certification.
#1- What Is the History of Zinc-Carbon Battery?
The zinc–carbon battery or ‘dry’ cell is well known since its invention in 1866 by G. L. Leclanché. The electrolyte of dry battery is paste-like, will not spill, and is easy to carry, so it has been widely used.
The original carbon dry battery was a paste-type zinc-manganese dry battery from a structural point of view. With the advancement of technology and the demand for high-capacity electrical appliances, it gradually transitioned to a cardboard-type zinc-manganese dry battery. The cardboard occupies a small space and the inside of the battery can be To accommodate more cathode materials, the release time is longer.
– Paste Zinc-Manganese Dry Battery is composed of zinc cylinder, electro-paste layer, manganese dioxide positive electrode, carbon rod, copper cap, etc. The outermost layer is a zinc cylinder, which is both the negative electrode of the battery and also serves as a container. It must be gradually dissolved during the discharge process; the center is a carbon rod that functions as a current collector, and the carbon rod tightly surrounds the carbon rod. A mixture of dark brown or black manganese dioxide powder and a conductive material (graphite or acetylene black), which together with carbon rods constitute the positive electrode body of the battery, also called carbon package. To avoid the evaporation of moisture, the upper part of the dry battery is sealed with paraffin or asphalt.
The electrode reaction of zinc-manganese dry battery is zinc electrode:
– Cardboard-Type Zinc-Manganese Dry Batteries are improved on the basis of paste-type zinc-manganese dry batteries. It is based on high-quality kraft paper with a thickness of 70-100 microns without metal impurities. The surface is coated with a prepared paste and then dried to make cardboard to replace the paste in the paste-type zinc-manganese dry battery. 状electrolyte layer. The actual discharge capacity of cardboard-type zinc-manganese dry batteries is 2 to 3 times higher than that of ordinary paste-type zinc-manganese dry batteries.
#2- What Are Zinc Carbon Batteries Made Of?
A single unit of carbon zinc-manganese dry battery is composed of the following parts: zinc cylinder, the electrolyte layer, carbon package, carbon rod, copper cap, sealing agent, battery cover and trademark, plastic sleeve, etc.
- The zinc cylinder is the container of the battery and the negative electrode of the battery. During the discharge of the battery, zinc is gradually dissolved.
- The electrolyte layer is a kind of separator paper, which is a kind of pulp paper layer.
- The carbon package is made of manganese dioxide mixed with conductive material graphite or acetylene black. It is the positive electrode of the dry battery.
- The carbon rod is located in the center of the charcoal bag and is the current collector of the charcoal bag.
- A copper cap is installed on the top of the charcoal bag, which is the positive terminal of the battery.
- The sealing agent has a sealing effect on the battery. Initially, asphalt was used as the sealing agent for carbon batteries. Now, glue is used instead of asphalt. The glue is lighter, has better sealing properties, and saves space.
- Most battery covers are made of plastic or tinplate for protection.
#3- What Is the Reaction Principle of Zinc-Carbon Battery?
Dry battery is a primary battery in chemical power supply. It is a kind of disposable battery. It uses manganese dioxide as the positive electrode and zinc cylinder as the negative electrode to convert chemical energy into electrical energy to supply an external circuit. In the chemical reaction, because zinc is more active than manganese, zinc loses electrons and is oxidized, while manganese gets electrons and is reduced. The voltage of the carbon zinc-manganese dry battery is 1.5V.
We use the thicker zinc can, purer manganese dioxide, imported glue, and use the most advanced production lines in the world. The leakage resistance of our battery is very good, very suitable for some high-end and low-power electrical appliances.
