Nowadays, energy storage technology develops rapidly, especially the lithium ion battery. Lithium ion battery is the most widely used energy storage device because of its good performance and maturity. In practical applications, lithium ion battery uses liquid electrolyte. It makes not only limited energy density of battery but also some safety problems which need to improve. All-solid-state fluoride ion battery is one of the new type of batteries. Its high energy density and good safety capture international research teams' attention. Now the key points of fluoride ion battery studying are electrodes and electrolytes. This study focuses on two types of electrolytes which have potential, La_(0.9)Ba_(0.1)F_(2.9) and BaSnF_4, which use planetary ball-milling to synthesis solid electrolyte samples and do crystal structure and electrochemical analysis of both electrolytes.
