Název v původním jazyce

Mesoporous/Microporous Li4Ti5O12/rutile-TiO2 as an anode material for lithium-ion batteries synthesized by the sol-gel method

Popis výsledku v původním jazyce

In this work, we presented a modified sol-gel method to synthesize the nanocrystalline composite composed of Li4Ti5O12 (LTO) and rutile-TiO2, and utilized it as an efficient anode material for lithium-ion battery application. The detailed structural studies revealed that the spherical shaped rutile nanoparticles of TILDE OPERATOR+D9110-20 nm were homogeneously distributed on the surface of LTO and therefore the mesoporous/microporous nature of the two-phase Li4Ti5O12-TiO2 (LTO-T) was exhibited. According to a series of galvanostatic charge/discharge tests, the LTO-T electrode with the mesoporous/microporous microstructure demonstrated the improved electrochemical performance, especially at a high C rate. Interestingly, the LTO-T electrode achieved an excellent specific capacity of 175 mAh gMINUS SIGN 1 and 155 mAh gMINUS SIGN 1 even after 50 charge/discharge cycles at 1C and 5C, respectively.
