super cheap earth element to advance new battery tech to the industry

september 19, 2018 by kayla wiles, purdue universitysodium normally explodes if exposed to water, but performs well in batteries as a powder, purdue researchers discovered. credit: purdue university video/vilas polmost of today's batteries are made up of rare lithium mined from the mountains of south america. if the world depletes this source, then battery production could stagnate. sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water—even just water in the air.worldwide efforts to make sodium-ion batteries just as functional as lithium-ion batteries have long since controlled sodium's tendency to explode, but not yet resolved how to ...
