  2. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4 Cl) or zinc chloride (ZnCl 2) electrolyte of the zinc–carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.

    Such storage can extend the life of alkaline batteries by about 5%; rechargeable batteries can hold their charge much longer, depending upon type. [69] To reach their maximum voltage, batteries must be returned to room temperature; discharging an alkaline battery at 250 mA at 0 °C is only half as efficient as at 20 °C. [33]

  9. Flexible battery - Wikipedia

    en.wikipedia.org/wiki/Flexible_battery

    Alkaline batteries are more durable than conventional zinc-carbon batteries under heavy load. An alkaline battery uses MnO 2 as the active material along with zinc anode, and KOH is used as an electrolyte here. A flexible alkaline cell offers several challenges because compared to zinc-carbon cells using weak acidic or neutral electrolytes, KOH ...
