An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide. Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline ...
Zinc–carbon batteries of various sizes. A zinc–carbon battery (or carbon zinc battery in U.S. English) [1][2][3][4] is a dry cell primary battery that provides direct electric current from the electrochemical reaction between zinc (Zn) and manganese dioxide (MnO 2) in the presence of an ammonium chloride (NH 4 Cl) electrolyte.

Typical Duracell 9V battery. Duracell Inc. is an American manufacturer of alkaline batteries, specialty cells, and rechargeables; it is a wholly owned subsidiary of Berkshire Hathaway since 2016. The company has its origins in the 1920s, through the work of Samuel Ruben and Philip Mallory, and the formation of the P. R. Mallory Company.
Battery leakage. A nickel–cadmium Varta barrel battery that has leaked onto the mainboard of a Korg Poly-61, causing massive corrosion to circuit board traces and legs of integrated circuits. Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment ...
A silver oxide battery (IEC code: S) is a primary cell using silver oxide as the cathode material and zinc for the anode. These cells maintain a nearly constant nominal voltage during discharge until fully depleted. [2] They are available in small sizes as button cells, where the amount of silver used is minimal and not a prohibitively ...
A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous oxidation–reduction reactions. An example of a galvanic cell consists of two different metals, each immersed in separate beakers containing their ...
Nominal cell voltage. 1.2 V. A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate (Zn ...
