Battery Capacity: Ampere-Hours, Coulombs and Moles of Active Material
This lesson is part of the course
In this lesson
You compute the theoretical capacity in mAh per gram of five electrode materials, the usable capacity of a fictional zinc cell and the material needed for a required capacity, and chart the materials side by side.
