Which is the best chemical battery?

Answer 1

A chemical battery is a battery with chemicals in it. Every electrical battery has chemicals which react to produce a potential difference (voltage) between the terminals. The term 'battery' actually refers to multiple cells (a car battery and 9-volt battery are examples). Most 'batteries' like AA, C, D etc only have one cell, but these are commonly referred to as batteries as well.

Answer 2

This varies from one type of battery to another:

• lead acid: plates lead and lead oxide, electrolyte liquid sulphuric acid
• standard carbon zinc: plates carbon and zinc (sometimes amalgamated with Mercury), electrolyte paste zinc chloride and manganese dioxide
• alkaline: plates carbon and zinc, electrolyte paste potassium hydroxide
• nickel-metal hydride (NiMH): plates nickel oxyhydroxide and any of several intermetallic compounds, electrolyte paste potassium hydroxide
• gravity cell: plates copper and zinc, electrolyte liquid copper sulfate with liquid zinc sulfate floating on top of it
• lemon cell: plates copper and zinc, electrolyte citric acid in lemon
• etc.

Almost any two different conductors can be used as the plates, and almost any acid, base, or salt can be used as the electrolyte. You can even make a cell by placing two different pieces of metal on you tongue (but this will give both an unpleasant feeling and a nasty taste in your mouth, I don't recommend trying it).

Answer 3

A standard dry cell battery is made from zinc and can filled with a paste of zinc chloride and ammonium chloride. At the centre is a graphite rod surrounded by a paste of manganese dioxide.

Answer 4

Carbon-Zinc
