چکیده
Spinel compound LiNi0.4Mn1.5Cr0.1O4 (LNMCO) and Li4Ti5O12 (LTO) were synthesized by different methods. The particle sizes of LiNi0.4Mn1.5Cr0.1O4 and Li4Ti5O12 were 05-2 um and 0.5-0.8 um, respectively. The LiNi0.4Mn1.5Cr0.1O4/Li4Ti5O12 (LNMCO/LTO) cell exhibited good electrochemical properties at high current rate such as 1 C. When specific capacity was determined based on the mass of LNMCO cathode, the LNMCO/LTO cell delivered 125 mAh g -1 at 1 C and 77 mAh g -1 at 5 C. The capacity retentions after 30 cycles were 94.4 % and 83.1%,

متن کاملFacile synthesis of nano-Li4 Ti5O12 for high-rate Li-ion battery anodes
One of the most promising anode materials for Li-ion batteries, Li4Ti5O12, has attracted attention because it is a zero-strain Li insertion host having a stable insertion potential. In this study, we suggest two different synthetic processes to prepare Li4Ti5O12 using anatase TiO2 nanoprecursors. TiO2 powders, which have extraordinarily large surface areas of more than 250 m2 g-1, were initiall...
