Lesson Plan: Secondary Galvanic Cells Chemistry
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe secondary cells and explain how they can be recharged.
Objectives
Students will be able to
- describe the differences between a secondary cell and a primary cell,
- describe the composition and main components of a lead–acid battery and a lithium–ion battery,
- explain, using half-equations, the discharging and charging reactions of a lead–acid battery and a lithium–ion battery,
- discuss the advantages and disadvantages of lead–acid batteries and lithium–ion batteries.
Prerequisites
Students should already be familiar with
- primary cells and batteries that cannot be recharged.
Exclusions
Students will not cover
- single-use (primary) cells or different types of secondary cells in detail, other than the lithium–ion battery and the lead–acid battery.
