Cells and batteries

How can we produce electricity

If we take two different metals and place them into an electrolyte

What are some facts about cells

-A cell can only produce electricity for a certain time period. Eventually the chemicals in the cell run out and reaction stops

-Cells only produce electricity if we use matos with different reactivities

What factors affect the voltage produced by a cell

-The offence in reactivity of electrodes(metals)

-The electrolyte used in a cell

How can a sell be made

A simple cell can be made by connecting two different metals in contact with an electrolyte.

What is a battery

By connecting two or more cells together in series to produce a greater voltage

What are Alkaline batteries

Batteries which donations cells which use irreversible reactions. So once the reactants are used up no more electricity is produced

-We can’t reverse reaction so they’re non-rechargeable batteries

What are rechargeable batteries and why can they be recharged

-They can be recharged

Rechargeable cells and batteries can be recharged because the chemical reactions are reversed when an external electrical current is supplied.
