ZinkKohlenstoff

ZinkKohlenstoff refers to a type of battery chemistry that utilizes zinc as the anode and carbon as the cathode material. These batteries are often primary (non-rechargeable) cells, meaning they are designed for single use. The electrolyte in a zinc-carbon battery is typically an aqueous solution of ammonium chloride and zinc chloride, or sometimes sodium chloride.

The electrochemical reaction involves the oxidation of zinc at the anode to form zinc ions, and the reduction of manganese dioxide (often used in conjunction with carbon) at the cathode. The carbon acts as a conductive additive and current collector for the cathode material. Zinc-carbon batteries are known for their relatively low cost and good shelf life, making them suitable for low-drain applications such as remote controls, clocks, and flashlights.

However, compared to other battery chemistries like alkaline or lithium-ion, zinc-carbon batteries generally offer lower energy density and power output. Their performance can also be significantly affected by temperature. Early forms of dry cell batteries were based on this technology. While largely superseded by alkaline batteries for many applications due to their superior performance, zinc-carbon batteries remain a viable and economical option for specific uses where high power is not a primary requirement.
