How a 270-year-old physics trick could supercharge affordable battery technology!
STORY CREDITS Writer: Manasasri Muralidharan Cover Photo: Assorted Batteries (Sourced from Envato) Researchers from India and Australia merge historical physics with modern materials engineering to create durable sodium batteries that could help meet clean energy goals. Roughly 270 years ago, Dr Johann Gottlob Leidenfrost from Germany observed a peculiar behaviour of water droplets on heated metal surfaces. In his manuscript, “A Tract About Some Qualities of Common Water,” he described how water skated over superheated metal surfaces as though friction had ceased to exist. This occurs when water or any liquid forms a vapor cushion on surfaces far above their boiling...
