A Low-Temperature Molten Salt Synthesis of LiNiVO4 Cathode Material for Lithium Ion Batteries
A newly developed molten salt method was applied at a temperature as low as 350°C to successfully synthesize an inverse spinel LiNiVO4 cathode by reacting lithium nitrate, nickel nitrate, and ammonium vanadate. As shown in XRD and TEM, the resultant product was a pure phase of LiNiVO4 without any other impurities. The powders showed a narrow particle size distribution with an average particle size of about 80 nm. No organic materials were introduced in the whole process.
