What is one of the chemicals in a battery?

Answer 1

This varies depending on the specific battery "chemistry" used.

• the old carbon-zinc batteries used - carbon, zinc-Mercury alloy (with iron grains contamination in the zinc), zinc chloride paste, water, manganese dioxide (to suppress hydrogen gas formation), porous paper separator
• modern alkaline batteries use - carbon, zinc, potassium hydroxide paste, water, manganese dioxide (to suppress hydrogen gas formation), porous paper separator
• lead-acid batteries use - lead, sulphuric acid, water
• nickel cadmium batteries - nickel oxide hydroxide, cadmium, potassium hydroxide paste, water, porous paper separator
• lithium manganese batteries - lithium, manganese dioxide, lithium perchlorate paste, propylene carbonate, propylene dimethoxyethane, porous paper separator
• lithium ion batteries - lithium nickel manganese cobalt oxide, carbon, lithium perchlorate paste, ethylene carbonate, porous paper separator
• etc,

Answer 2

Yes,

There are different chemicals in different batteries. In a standard AA Battery there is zinc which can be filled with a paste of zinc chloride and ammonium chloride. At the centre is a graphite rod surrounded by a paste of manganese dioxide.

In an AAA battery there can be but it depends on the brand of the battery:

- Nickel (NiCd or NiMH)

- Zinc (Zinc Carbon)

- Lead (Lead Acid)

- Carbon (Zinc Carbon)

common acids and alkalis include:

- Hydrochloric Acid

- Sulphuric (Sulfuric in US) acid

- Maganese Dioxide (Alkaline)
