Why Do Li-Ion Batteries Die? - and How to Improve the Situation?

This seminar by Dr. Jeff Dahn explains why Li-ion batteries die and, using examples from research, how changes to their chemistry can greatly improve their lifetime. The seminar took place at the Waterloo Institute of Nanotechnology and is presented in this resource as a video recording. Discussed are testing methods, characteristics of different Li-Ion battery types, additives, research results, and more. It's suggested through design improvements that Li-ion batteries can eventually be made to last for 20, 30, or even 50 years.
