Alkaline battery - Wikipedia

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, nickel and cadmium, or nickel and hydrogen. Compared with … See more Batteries with alkaline (rather than acid) electrolyte were first developed by Waldemar Jungner in 1899, and, working independently, Thomas Edison in 1901. The modern alkaline dry battery, using the zinc/ See more The capacity of an alkaline battery is greater than an equal size Leclanché cell or zinc chloride cell because the manganese dioxide is purer and denser, and less space is taken up … See more The amount of electrical current an alkaline battery can deliver is roughly proportional to its physical size. This is a result of decreasing internal … See more Some alkaline batteries are designed to be recharged a few times, and are described as rechargeable alkaline batteries. Attempts to recharge standard alkaline batteries may … See more In an alkaline battery, the negative electrode is zinc and the positive electrode is manganese dioxide (MnO2). The alkaline electrolyte of potassium hydroxide (KOH) is not consumed during the reaction (it is regenerated), only the zinc and MnO2 are consumed during … See more The nominal voltage of a fresh alkaline cell as established by manufacturer standards is 1.5 V. The actual zero-load voltage of a new alkaline battery ranges from 1.50 to 1.65 V, depending … See more Alkaline batteries are manufactured in standard cylindrical forms interchangeable with zinc–carbon batteries, and in button forms. Several … See more WebThese batteries are the most commonly used worldwide in flashlights, toys, radios, compact disc players, and digital cameras. There are three variations: the zinc-carbon battery, the zinc chloride battery, and the alkaline battery. All provide an initial voltage of 1.55 to 1.7 volts, which declines with use to an end point of about 0.8 volt. The zinc-carbon battery, … WebTheoretically, an acidic environment could make the MnO 2 cathode achieve higher energy density, whereas an alkaline Zn anode with a standard reduction potential below that of a neutral Zn anode ... form submit button editing
