Are sodium-based batteries the wave of the future?
Researchers at the Georgia Institute of Technology have found new evidence suggesting that batteries based on sodium and potassium hold promise as a potential alternative to lithium-based batteries. The research team looked at how three different ions -- lithium, sodium and potassium -- reacted with particles of iron sulfide, also called pyrite and fool's gold. The team found that iron sulfide was more stable during reaction with sodium and potassium than with lithium, indicating that a battery based on sodium or potassium could have a much longer life than expected.
