hey, i really need help on summative project on battery.

TOPIC:
"Find out how the concentration of the reacting materials can affect the voltage of the cell"...?

cant seem to find any information on how the concentration of chemicals can affect the voltage of the battery...

more NiNH in a battery = higher voltage???

Nernst Equation?

If this is a summative project, you'll want to talk about a few things;

How does a battery work?
What's in a battery?
How each component of a battery is measured (mass, concentration, density maybe?)
How the change in concentration works to increase (or decrease) voltage

There's different kinds of batteries too...I don't know if you have a particular one in mind...but this post will turn out to be an interesting one.

Good luck!
