基于碱土金属氟化物并具有CeF 4和UF 4作为掺杂剂的浓缩的氟化物过量固溶体是适用于薄膜原电池的固体电解质。使用Pb或Ca作为阳极，浓缩的固体溶液作为电解质，以及BiF 3或BiO 0来制造原电池。一楼二层。S作为阴极。研究了300 ~ 540 K空气中的放电特性。电池是可充电的。BiF 3的电性能进行了研究，并与BiOo报道的数据进行了比较。lF2。S.部分放电的电池含有主要由Pb组成的阳极钝化层。2OF_2，如果Ca是阳极，则为名义上纯的CaF_2，其中氟化物物质携带电流。具有萤石结构的氟离子导体已被探索作为固态原电池中的固体电解质。值得注意的是，未掺杂的氟化铅已被用于真空蒸发薄膜原电池Pb-CuF 2（1）、Pb-BiF 3（2）和Pb-AgF（1，2）中，而AgF掺杂的PbF-已被用作电池Pb [BiO] 0.一楼二层。8（3）。在后一种电池的制造中，使用固体电解质-乙酸乙酯和阴极-乙酸乙酯混合物。乙酸乙酯在室温下的快速蒸发允许一种简单快速的方法来构建可靠的全固体电池（3）。
Concentrated fluoride-excess solid solutions based on the alkaline earth fluorides and with CeF~ and UF4 as dopants are suitable solid electrolytes for application in thin film galvanic cells. Galvanic cells were fabricated using Pb or Ca as the anode, the concentrated solid solutions as electrolytes, and either BiF3 or BiO0. 1F2. s as the cathode. Discharge characteristics were studied in air from 300 to 540 K. The cells are rechargeable. The electrical properties of BiF3 were studied and compared with data reported for BiOo. lF2. s. Partly discharged cells contain anode passivation layers which consist mainly of Pb. 2OF2 when Pb is the anode, and of nominally pure CaF2 in which fluoride interstitials carry the current if Ca is the anodeFluoride ion conductors with fluorite structure have been explored as solid electrolytes in solid-state galvanic cells. Notably, undoped lead fluoride has been employed in vacuum-evaporated thin-film galvanic cells Pb-CuF2 (1), Pb-BiF3 (2), and Pb-AgF (1, 2), while AgF-doped/~-PbF~ has been used as a solid electrolyte in the cell Pb [BiO0. 1F2. 8 (3). In the fabrication of the latter cell, solid electrolyte-ethyl acetate and cathode-ethyl acetate mixtures are used. The rapid evaporation of ethyl acetate at room temperature allows an easy and fast way to construct reliable allsolid cells (3).
