Alkaline battery 硷性电池
(重定向自Alkaline batteries)
Alkaline batteries (IEC code: L) are a type of primary battery dependent upon the reaction between zinc and manganese(IV) oxide (Zn/MnO2). A rechargeable alkaline battery allows reuse of specially designed cells.
Compared with zinc-carbon batteries of the 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.
