The speaker contrasts biology’s complex nanotechnological capabilities with the difficulty of making two material interfaces work together in batteries, where lithium can break the interface.

“there are all these dendrites that form like basically the lithium will form these structures that go into salt electrolyte and crack it and you look at that and you think this is so primitive compared to biology like in biology these systems can do such complex nanotechnological technological progress whereas we can't even like make two interfaces work with each other because lithium will break it yeah but then I guess inorganic stuff can be very resistant to high temperature”
