In this podcast i discuss the following points raised by Eveline from Delft University of Technology (original text):
In my group we do a lot of work with solid state inorganic electrolytes. I would be extremely interested in your view about the scale up and economics of such systems! For example, in your last Podcast you describe how the LPS/Polymer cells are made.
1. How could such processes be implement on a larger scale and for larger batteries?
2. And if two polymer interfaces are needed, what is the benefit compared to a composite polymer electrolyte with inorganic fillers?
3. And then, compared to standard lithium-ion, is it even possible that the technology could ever compete economically?
Claudiu B. Bucur obtained his Ph.D. in 2008 from Florida State University under the mentorship of distinguished Leo Mandelkern Professor of Polymer Science, Joseph B. Schlenoff. He studied the manner in which polyelectrolyte multilayers assemble, and how doping them with ions changes their mechanical and thermodynamic properties. In 2010 he completed his postdoctoral studies at the USDA Agricultural Research Service Labs, where he investigated corrosion inhibition via biomembranes. Dr. Bucur then joined the Post Lithium Ion Research Group at the Toyota Research Institute of North America, where he focused on metallic anodes such as magnesium, lithium, sodium, and their electrolytes as well as high capacity conversion cathodes such as the sulfur cathode. He expanded upon his experience with polymers, corrosion, and interfaces and was able to advance many areas in the battery field. Currently, Dr. Bucur is Chief Engineer for new battery and solid electrolyte projects at Great Wall Motor, the largest SUV manufacturer in China. He is fascinated by energy storage and dreams of creating the ultimate battery.

One thought on “28. Economic and technical considerations of solid state batteries”
Hi Claudiu, thank you for this informative episode!
You debunked my assumption that solid-state-batteries have a higher energy density than batteries with liquid electrolytes. And emphasised that safety is the selling point.
What about the longevity (also a commonly mentioned advantage of solid state batteries)?
