On the mechanism of ion exchange in zirconium phosphates—XVII Dehydration behavior of lithium ion exchanged phases Academic Article uri icon


  • The phases formed by the dehydration of lithium exchanged α-zirconium phosphate, Zr(HPO4)·H2O, were determined by a combination of X-ray, TGA and DTA studies. Samples containing 10, 20, 30 ... 100% of theoretical lithium ion capacity were examined. The data are summarized in a phase diagram which however is not an equilibrium diagram because of the slowness of approach to equilibrium. The numerous phases obtained and the ease with which they rearrange indicates a high mobility for the incorporated cations. This suggested that α-zirconium phosphate may behave as a solid electrolyte and indeed this was demonstrated by having it serve in that capacity in a small sodium sulfur battery. © 1977.
