alkaline battery definition
alkaline. adj. 1. (Chemistry) having the properties of or containing an alkali. Alkaline batteries are a type of primary battery dependent upon the reaction between zinc and manganese(IV) oxide (Zn / Mn O 2). A rechargeable alkaline battery allows reuse of specially designed cells. 1. alkaline-relating to or containing an alkali; having a pH greater than 7; alkaline soils derived from chalk or limestone. alkalic. chemical science, chemistry-the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions. Compared with zinc-carbon batteries of the Leclanche leclanché or zinc chloride, types alkaline batteries have a higher energy density and longer-shelf, life with the same. Voltage button cell-silver oxide batteries have higher energy density and capacity but also have a higher cost than-similar size alkaline. cells The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, instead of the acidic ammonium chloride or zinc chloride electrolyte of the zinc-carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes. Confidence votes 77.6K. The non-alkaline battery is probably best defined by comparing it to the alkaline battery. Both are chemical cells, but the alkaline battery has as an electrolyte a basic solution of potassium hydroxide. (A base is often said to be alkaline in chemistry.) The non-alkaline battery uses zinc and ammonium chloride, which are acidic, as an electrolyte. The alkaline battery packs a higher chemical energy density than the regular or, as it is marketed, heavy duty or industrial battery. Alkaline battery. Alkaline batteries are a type of primary batteries dependent upon the reaction between zinc and manganese dioxide. A rechargeable alkaline battery allows reuse of specially designed cells. Compared with zinc-carbon batteries of the Leclanche leclanché or zinc chloride, types alkaline batteries have a higher energy density and longer-shelf, life with the same. voltage Alkaline batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. In Japan alkaline batteries account for 46% of all primary battery sales. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, instead of the acidic ammonium chloride or zinc chloride electrolyte of the zinc-carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes. al·ka·line. adj. 1. Of, relating to, or containing an alkali. 2. a. Having a pH greater than 7. b. Having a relatively low concentration of hydrogen ions. 3.
A type of primary battery dependent upon the reaction between zinc and manganese oxide.
