Webinar: Lithium ion battery research and developments
Synopsis of the presentation
Lithium-ion batteries are amazing. I will show an example of a Li-ion cell that has undergone 27,000 100% depth of discharge cycles over 8 years. This is enough to power a vehicle for over 10 million km or around the circumference of the Earth about 250 times. Such Li-ion cells can easily support vehicle to gird and second use. I will discuss:
- How does one make such a wonderful Li-ion cell?
- How does one stop common degradation modes as we have done here?
- The Li-ion cells in most EVs are not this good but they are still plenty good for V2G if operated "sensibly". What does this mean?
- What are best practices for charging EV batteries and how can I ensure my EV battery lasts as long as possible?
NOTE that this webinar starts one hour later than the usual start time due to the timezone of the speaker.
