Pressure in charge. Neglected parameter in hydrothermal synthesis turns out to be crucial for electrochemical properties of ammonium vanadates
Abstract
Ammonium vanadates are of great interest as they exhibit unusual electrical and sensory properties.(NH4)2V6O16and (NH4)2V10O25$8H2O with various morphology were obtained in the hydrothermalsynthesis under controlled temperature and pressure. It was shown, that the pure (NH4)2V10O25$8H2Owas obtained under 50 bar of initial pressure, whereas lower pressure lead to the mixture of twocompounds. The influence of the pressure was studied for thefirst time, and the results demonstrated itsutmost importance. Moreover, the electrochemical performance of synthesized (NH4)2V10O25$8H2Owasstudied, revealing its excellent behavior as cathode material for Li-ion batteries. To the best of our knowledge, there is no information available on using this structure in such application.
