The structure of the alkaline button battery is the exact opposite of the acid battery, with the negative electrode in the centre of the cell, zinc in powder form, the positive zone in the outer layer, a mixture of MnO2 and KOH, and a steel cylinder in the outer shell.

Alkaline button battery is a disposable battery with zinc and manganese dioxide as electrodes. The alkaline electrolyte used is potassium hydroxide or sodium hydroxide. These cells have a stable voltage and offer better energy density and leakage resistance than carbon zinc cells. This is primarily due to the purer and denser manganese dioxide anode material, which reduces the space occupied by internal components. Most market players have shifted their attention to rechargeable chemicals, such as nickel metal hydride and lithium ion. This has led to the consolidation of the alkaline button battery market.
The alkaline button battery has the advantages of durability, high current flow, long storage life and a less corrosive casing than conventional dry cell batteries (also known as carbon zinc dry cell batteries), because the potassium hydroxide in the alkaline button battery is in a liquid state, unlike ordinary dry cell batteries which are filled with a solid paste, so the internal resistance is lower. In addition, the zinc in alkaline batteries participates in the reaction in the form of granules and has a larger contact area with the electrolyte, thus generating a flow of electricity three to five times greater than that of an ordinary dry cell of the same volume.
In addition, when discharging an alkaline battery, no gas is produced internally, whereas some gas is produced when discharging a normal dry cell, so the voltage of the alkaline button batteryis also more stable. Alkaline batteries have very little filling material that is not involved in the chemical reaction, so they can be made smaller. As a result, the alkaline button battery is more durable than a normal battery of the same size.
The alkaline button battery has increased the relative area between the positive and negative electrodes due to the use of an opposite electrode structure to that of conventional batteries and the use of a highly conductive potassium hydroxide solution instead of ammonium chloride and zinc chloride solutions. The negative zinc has also been changed from flake to pellet form, increasing the reaction area of the negative electrode, which, together with the use of a high performance manganese electrolyte, has led to a significant improvement in its electrical properties.
The alkaline button battery plays a very important role in improving production efficiency. Guangzhou Dolphin Information Technology Co., Ltd. has various alkaline button battery that can provide the increasing of products, and make them more effective, reliable, and consistent.
