In-situ studies of lithium/ silver vanadium phosphorous oxide batteries using synchrotron based energy dispersive x-ray diffraction

摘要

The powerful synchrotron analysis technique energy dispersive x-ray diffraction (EDXRD) has been utilized to achieve greater insight into the distribution of silver nanoparticles formed on initial reduction of lithium / silver vanadium phosphorous oxide, Ag_2VO_2PO_4, and silver vanadium diphosphate, Ag_2VP_2O_8, (SVOP family of materials) batteries. By combining the results of EDXRD measurements with ex-situ methods, we are able to effectively probe the discharge mechanism of the bimetallic materials to understand the reduction displacement discharge process.
