In ordinary alkaline batteries it is potassium hydroxide, sometimes called potash or potassium lye.
Other battery chemistries may contain a different alkali, a salt, or an acid.
For example a battery used in most modern US nuclear weapons is called a thermal battery and uses a salt as the electrolyte. When the weapon is fired a heat source rapidly heats the battery, melting the salt and activating the battery powering up the weapon's electronics. Such batteries have an almost infinite shelf life.
They are alkalis, such as sodium carbonate, used by industries, such as glassmakers.
KOH and LiOH are examples of alkalis, which are bases that dissolve in water to produce hydroxide ions (OH-). They are commonly used in various applications, such as in the production of soaps and batteries.
Acids and alkalis (properly known as bases) are often used in the form of solutions, but most can exist outside a solution as well.
Bases are not called alkalis. Alkalis are a specific subset of bases that are soluble in water. All alkalis are bases, but not all bases are alkalis.
maybe
No. acids are corrosive, alkalis are caustic.
All alkalis are soluble in water.
these are rechargeable batteries used in cell fones
Plutonium is not used in batteries.
alkalis are corrosive, normally water soluble and are very soapy.
in inverter batteries
Acids are used in industries for food processing, metal cleaning, and pharmaceutical production. Alkalis are used for soap and detergent manufacturing, water treatment, and in the production of chemicals like fertilizers. Both acids and alkalis play vital roles in various industrial processes due to their chemical properties.
