carbon zinc aa battery
The carbon zinc AA battery is a classic primary cell battery that has been a reliable power source for decades. This battery type utilizes a zinc anode, a manganese dioxide cathode, and an electrolyte composed of ammonium chloride or zinc chloride. Operating at 1.5 volts, these batteries are designed for moderate drain applications and offer a cost-effective solution for everyday electronic devices. The construction involves a zinc can serving as both container and anode, with a carbon rod acting as the current collector in the center. The space between is filled with a paste mixture containing manganese dioxide, carbon black, and electrolyte. Carbon zinc AA batteries excel in devices with intermittent use patterns, such as remote controls, wall clocks, and basic electronic toys. Their shelf life typically extends to 2-3 years when stored properly at room temperature. While they may not match the performance of newer battery technologies in high-drain devices, they remain popular due to their affordability and widespread availability. The manufacturing process is well-established and environmentally considerate, as these batteries contain no mercury and can be disposed of through standard waste channels.
