Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. The Georgia Tech team sought to overcome those obstacles by using the solid polymer electrolyte.
