Lemon Batteries
Experiment
Updated September 2011
How can something as small
as a lemon have enough
power to do anything?
Updated September 2011
The same question can be asked of
nano scale batteries.

However, nano batteries are showing efficiencies up to
10 times more than any current battery. The idea is that if one
nano sized battery does not make enough power, trillions of
nano batteries in arrays and in series will.
After all, a battery is merely made
of two metals and an electrolyte

This module is one of a series designed to introduce faculty and high school
students to the basic concepts of nanotechnology. Each module includes a
PowerPoint presentation, discussion questions, and hands-on activities, when
applicable.
The series was funded in part by:
The National Science Foundation
Grant DUE-0702976
and the
Oklahoma Nanotechnology Education Initiative
Any opinions, findings and conclusions or recommendations expressed in the
