Abstract

CaF2 and MgF2 were tested as active anode materials for solid-state fluoride-ion battery based on thin-film electrolyte. Tin oxide, indium tin oxide, and carbon nanotubes were applied as electronically conductive additives in the anode materials to increase the electronic conductivities. X-ray diffr...
