“…PbSnF4 has been found to possess a high ionic conductivity (2), and is among the best-known anionic conductors. Because of the use of fluoride electrolytes as thin films in galvanic cells, specific electrodes for fluoride ions, or gas detectors (3)(4)(5)(6), considerable attention has been directed at experimental work on fluorides with the fluorite-type structure, including the family MSnF4 where M = Pb, Ba, Sr.…”

Can. J. Chem. 66,549 (1988).We have measured the heat capacity of the fast ion conductor PbSnF4 at 10.3 < T < 352 K by adiabatic calorimetry. Our resultsshow anomalous values in the C,,,, in the region 300 < T < 352 K . These are associated with the a-P crystallographic transition reported at 353 K. Because the upper temperature limit of our cryostat is around 354 K, it was impossible to follow the phase transition to completion. A more subtle anomaly in the C,,,,, was detected between 130 and 160 K. Standard molar thermodynamic functions are presented at selected temperatures from 5 to 350 K.

The electronic conductivities of solid solutions Lal_xBaxF3_x (0 • x • 0.0952) were investigated up to 533 K using the Hebb-Wagner dc polarization technique. The electrochemical cell (-) LalLat_xBaxF3_xlPt(+) has been utilized with Pt as the ion-blocking electrode. Under steady-state conditions the La I-xBaxF3-x solid solutions exhibit electronic conductivity. The electronic conductivity vanishes in pure LaF~: Together with ac conductivity measurements it appears that the ionic transference number for Lal_xBaxF3_x (0 • x • 0.0952) is essentially unity over the temperature range studied

“…The early studies on thin solid electrochemical devices were made on fast anionic conductors such as rare-earth fluorides, e.g., LaF3, CeF3 [38][39][89][90], lead fluorides, e.g., PbF2, PbSnF4 [24][25][40][41]68,[91][92][93][94][95], doped zirconia, e.g., ZrOz-CaO, Zr02-Y 203, Zr02-MgO and doped ceria, e.g., Ce02-CaO, Ce02-Y 203 [5][6][7][8]16,37,[96][97], and L\-alumina [6,99].…”

The purpose of this chapter is to introduce the area of solid-electrolyte thin-films and to discuss the various process/property/applications relationships which have been developed in this field. Thin-film technology is examined from the interrelated viewpoints of product application, materials structure/properties relationships, and manufacturing-deposition methods. Special emphasis is given to the thin-film materials properties of lithium-borate glasses, which are likely to have an impact on electrochemical device performance, coupled with the various techniques employed to control those properties.Thin-films form an integral part of products which cannot be made using bulk components. For some, this is because the films themselves possess unique properties which cannot be duplicated in bulk [1]. In still others, the thickness of a material may impart special functional advantages. The use of thin-film solid-oxide electrolytes in low temperature fuel cells is one such potential example [2].The concept of reducing the internal resistance of solid-state battery was the first reason for the use of thin-film techniques in battery technology and has been invoked many times by investigators attempting to use low-conducting materials. The use of thin-film technology for the formation of lithium-microbatteries offers various advantages: (i) thin-film technology is widely used in advanced microelectronics, (ii) thinning of layers gives a lower electrical resistance in the transverse direction, (iii) thin-film technology provides a clean surface for the compound and may improve the electrode-electrolyte interface contact by reducing the interface resistance, (iv) film deposition of alkali metals such as lithium is easy, (v) film deposition of lamellar compound allows the orientation of the layers with the van der Waals planes perpendicular to the separator surface, (vi) deposition of the C.
