Single Phase LiSUB4/SUBTiSUB5/SUBOSUB12/SUBSynthesis for Nanoparticles by Two Steps Sintering

摘要

Li4Ti5O12 has been noticed about a negative electrode of a high powered and safe lithium ion secondary battery. These properties require single phase, high crystallization, larger specific surface area and fine nanoparticles. This study carried out the noble synthesis of Li4Ti5O12 using a solid phase synthesis by two steps sintering. These results showed Li4Ti5O12 of 6.1 m2·g-1?and diameter of 110 nm with the single phase and high crystallization. Li2TiO3 will play an important rolein this reaction, obtained by pre-sintering as a precursor.
