Carbon-zinc batteries, also known as zinc-carbon batteries, are among the most commonly used primary (non-rechargeable) batteries due to their low cost and relatively simple manufacturing process. Here’s a breakdown of the production steps and associated costs:
Zinc Anode: The outer casing of the battery typically serves as the zinc anode, which is relatively inexpensive and readily available.
Manganese Dioxide Cathode: The cathode material, manganese dioxide, is crucial for the battery's electrochemical reaction.
Electrolyte: An ammonium chloride or zinc chloride paste serves as the electrolyte, providing an environment for ion flow.
Carbon Rod: Positioned in the center of the battery, the carbon rod collects the electrical charge.
Preparation of the Zinc Anode: Zinc is formed into a cylindrical shape to serve as the battery’s container and negative electrode.
Inserting the Electrolyte Paste: A mix of ammonium chloride and/or zinc chloride, often combined with starch or another thickener, is inserted as a paste to act as the electrolyte. This paste is placed between the zinc casing and the cathode materials.
Adding the Cathode Material: Manganese dioxide powder is mixed with other conductive materials and packed tightly inside, around the central carbon rod.
Assembly and Sealing: The components are then assembled, with the carbon rod placed in the middle, surrounded by the cathode mixture and the zinc anode as the outer casing. The battery is sealed to prevent leaks and improve shelf life.
Quality Testing: Finished batteries undergo quality tests to ensure they meet standards for capacity, voltage, and shelf life.
Raw Material Costs: Zinc and manganese dioxide are relatively affordable, which helps keep production costs low. However, any price fluctuations in these raw materials can impact overall costs.
Production Scale: Large-scale production helps lower costs per unit, making carbon-zinc batteries very affordable.
Manufacturing Process: The process is straightforward and highly automated in most factories, which keeps labor and operational costs relatively low.
The production cost for a carbon-zinc battery is generally low compared to other battery types, often ranging between $0.10 to $0.50 per cell, depending on the scale of production, raw material prices, and specific battery size.
While carbon-zinc batteries are inexpensive to manufacture, they have lower energy density and shorter lifespan compared to newer battery technologies like alkaline or lithium-ion, which is why they are typically used in low-drain devices such as remote controls, flashlights, and clocks.
