My Notes
Description

A little more than 5 slides.... but hey batteries are important! Often there are not good slides available to introduce batteries, broadly, so I went a made them! These slides were also created to accompany the LO on redox flow batteries. This set of slides reviews alkaline batteries introduced in general chemistry and transitions to more modern approaches to batteries including lithium ion batteries and redox flow batteries. This work highlights the 2019 Nobel Prize work for lithium ion batteries. In addition, there are slides that show the advancement of electric vehicles and the use of lithium ion batteries in their production. 

This slides are intended to serve as an introduction to lithium ion batteries and applications of them in electric vehicles.

Learning Goals
Students should be able to:
•Describe the history of the lithium ion battery
•Describe how a lithium ion works
•Sketch the basic features of a lithium ion battery
•Discuss the contributions of Whittingham, Goodenough and Yoshino to the 2019 Nobel Prize in chemistry and commercialization of the lithium ion battery
•Compare and contrast advantages and disadvantages of lithium ion batteries
 
•Explain how batteries are used to store extra energy
•Describe features of different types of electric vehicles
•Recognize the differences between hybrid and all-electric vehicles
•Assess the advantages and disadvantages of different electric vehicles
 
•Define redox flow batteries
•Outline the design features of a redox flow battery
•Compare and contrast a redox flow battery to traditional battery
 
Implementation Notes

I used these slides to create a video (not included) for my students on batteries. Often alkaline batteries are covered only in general chemistry and very little is done to discuss more modern battery technology. I created 3 different videos on the content (they correspond to the breaks in the learning goals above) one on batteries (broadly), one of electric vehicles and another on flow batteries. The content of the videos was about 35 minutes and given to the students before our in class meetings. 

This could be used to supplement content on batteries elsewhere in the curriculum.

I used this for a green chemistry and sustainability course where not all students took inorganic chemistry yet. 

Time Required
35-45 minutes
Evaluation
Evaluation Methods

I like to follow up these videos with a set of pre class questions to answer and in class questions that expand upon the concepts. In addition, I used this in conjunction with the redox flow battery LO.

Evaluation Results

Students generally understood the concepts presented and could apply them to the questions asked in class and using the Redox Flow battery literature discussion.
