Abstract

Li4Ti5O12 anode material is rapidly becoming a central focus in the realm of lithium battery anode material research. This study introduces the synthesis of Li4Ti5O12 using the eutectic mixed molten salt method with different titanium sources. The findings reveal that the Li4Ti5O12 produced using anatase TiO2 as titanium source with LiOH–LiNO3 as the eutectic mixed molten salt demonstrates outstanding electrochemical characteristics. Notably, the discharge capacities attained are remarkable, measuring 134.67, 126.3, and 111.91 mA h g–1 at rates of 2.0, 5.0, and 10 C, respectively. After 60 cycles, when the rate is reset to 0.2 C, the capacity retains 98.75% of its initial capacity. Our research has demonstrated that the eutectic mixed molten salt method is a practical powder technology for producing high-performance Li4Ti5O12 anode material.
