N2 - As a potential material on lithium ion battery, the composite Li4Ti5O12 (LTO) has a limitation due to its low theoretical capacity compared to graphite. To decrease the limitation, this research was conducted by adding activated carbon and SnO2 to LTO. The addition of activated carbon was conducted in 1%, 3% and 5%. Meanwhile, the addition of SnO2 was conducted in 10%. LTO was synthetized by using sol-gel method, hydrothermal method and mechano-chemical method. The sample was characterized with XRD and SEM-EDX. The XRD results showed that SnO2 particle were formed with no residue from previous reaction. The results of SEM-EDS showed that SnO2 particle had a small size and distribute evenly as the active carbon. Furthermore, to determine the addition effect of activated carbon and SnO2 on electrochemical performance of the battery, we conducted EIS, CV and CD testing. The results of CV testing showed that the addition of activated carbon increased the specific capacity of LTO. Meanwhile, the results of CD testing showed that the addition of activated carbon reduced the capacity loss on high c-rate.
