Abstract
A novel oxalic dihydrazide (ODH) has been identified as a fuel for solution combustion synthesis to prepare LixMy(PO 4)z compounds as a cathode material for lithium battery applications. These compounds have been synthesized at 850°C using a mixture of Ar:H2 (90:10) atmosphere, wherein oxalic dihydrazide acts both as a combustible fuel and a carbon source. This resulted in a higher carbon content weighing ca. 12 and 8% for poly (Li3V2(PO 4)3/C) and pyrophosphate (LiVP2O7/C) composites as opposed to the insitu added super P carbon was only 5 wt.%. The electrochemical behavior of these cathodes showed reversible intercalation and deintercalation of lithium ions while exhibiting specific capacities of 168 and 100 mAh/g with good capacity retention. The role of ODH assisted combustion synthesis (ODHAC) on the physical and electrochemical behavior of the title compounds has been demonstrated.
