“…Consequently, the fluoride-ion electrolyte matrix identified as tysonite-type fluoride has emerged as the most promising option. 9,[12][13][14][15][24][25][26][27][28][29] A significant proportion of the research conducted on tysonitetype solid electrolytes has focused on enhancing the fluorideion conductivity by the doping modification of LaF 3 . 9,24,25,30 In the study conducted by Stefan Breuer and colleagues, the process of incorporating Ba 2+ ions into LaF 3 was achieved by high-energy mechanical milling.…”
