Sandia National Laboratories study voltage loss across battery interfaces

Scientists at Sandia National Laboratories may have discovered a way to make a longer-lasting, more efficient battery. The team used Kelvin probe force microscopy to locate places where electron flows get stuck.  Solid-state batteries use solid electrolytes instead of electrochemical gels and liquids. Researchers suspected that there was a loss of voltage at interfaces within… Read more »
