Electrochemical Properties of Trirutile-type Li₂TiF₆ as Cathode Active Material in Li-ion Batteries

抄録

The electrochemical properties of lithium hexafluorometalates as positive electrode materials were studied. Trirutile-type Li₂TiF₆ was synthesized through a complex-formation reaction under mild temperature conditions. In addition, a spray-drying technique was used to obtain electrodes with a large surface area. The electrochemical performance of the resultant Li₂TiF₆ powders was investigated vs. Li metal as negative electrode. Li₂TiF₆ exhibited an initial discharge capacity of 100 mAh g⁻¹ at 2.7 V.
