摘要

LiNiVO_4, an inverse spinel containing lithium, nickel and vanadium ions respectively in their +1, +2 and +5 oxidation states is still being considered as an arguably interesting compound of high voltage cathode, for the possible existence of deliberate tunnels to facilitate the movement of Li~+ ions. To circumvent the problems related to the requirement of tedious synthesis procedure, identification of alternate methods to synthesize the title compound at a relatively lesser reaction time and temperature becomes essential. In this context, the present study accomplishes a novel cost effective method comprising the participation of certain carbonaceous and/or nitrogenous combustible components such as Gelatin (G), Hydrazine hydrate (HH), Oxalyl di hydrazide (ODH) and Dimethyl glyoxime (DMG) to synthesize phase pure powders of LiNiVO_4. PXRD, FTIR, SEM, BET surface area, and charge-discharge studies were carried out for the product prepared from the above-mentioned combustion aiding sources. Details about the synthesis, characterization and performance of the high voltage category LiNiVO_4 compound synthesized using "soft chemistry route" will be highlighted in the present study.
