Facile molten salt synthesis of Li(2)NiTiO(4) cathode material for Li-ion batteries

Well-crystallized Li(2)NiTiO(4) nanoparticles are rapidly synthesized by a molten salt method using a mixture of NaCl and KCl salts. X-ray diffraction pattern and scanning electron microscopic image show that Li(2)NiTiO(4) has a cubic rock salt structure with an average particle size of ca. 50 nm. C...

Sumario:Well-crystallized Li(2)NiTiO(4) nanoparticles are rapidly synthesized by a molten salt method using a mixture of NaCl and KCl salts. X-ray diffraction pattern and scanning electron microscopic image show that Li(2)NiTiO(4) has a cubic rock salt structure with an average particle size of ca. 50 nm. Conductive carbon-coated Li(2)NiTiO(4) is obtained by a facile ball milling method. As a novel 4 V positive cathode material for Li-ion batteries, the Li(2)NiTiO(4)/C delivers high discharge capacities of 115 mAh g(-1) at room temperature and 138 mAh g(-1) and 50°C, along with a superior cyclability.
