Past podcast on lithium ion separators

The Holy Grail of anodes is a lithium metal anode. Taming this temperamental beast has been unsuccessful so far, but it is bound to change. In this podcast I discuss a composite separator membrane which enables plating lithium with 3x the speed and 3x the quantity (capacity) of commercial lithium ion cells.


6. Lithium metal anodes (fast as snails?!)

Faster Li plating through LLZO solid electrolytes. Latest from the Sakamoto group.
LLZO solid electrolyte pelltet. Easy to work with in small areas. But how can large, thin sheets be made for commercial applications?

Plating lithium metal anodes through inorganic solid electrolytes is challenging and slow due to proliferation of dendrites along the grain boundary where ionic conductivity is higher. Sakamoto’s group shares evidence of rate improvements without dendritic growth with LLZO solid electrolytes.
