Electrochemical Cells & Batteries
Daniel Cell
Daniel Cell
- A Daniell Cell is based on the premise that the two solutions (electrolyte solutions) want to be electrically neutral. This is achieved by the salt bridge!
- Watch the video to see how electrons are passed from one electrode to the other in order to create ions in the solutions ...
Zinc-Carbon Battery
Zinc-Carbon Battery
For less sciency people, we would say that this is what most "A", "AAA", "C" or "D" batteries are made of ... Fortunately, we are more sciency than most, so we would say that this is what an "A", "AAA", "C" or "D cell is made from!!! The differences in these two materials used (zinc and manganese oxide) creates a potential difference of about 1.5V.

The 9V Battery
The 9V Battery
Yes, its actually a battery ... not just a single cell!!!
Watch the Disassembling a 9V Battery video to the right to see what makes this a battery, and not just a cell!
