| description | Lithium
titanate (Li4Ti5O12 or LTO) is a very
promising anode material to replace graphite in li-ion batteries due to its
safety and fast-charging ability. However, due to the low theoretical capacity
of LTO, a strategy must be developed to overcome this problem. Synthesizing LTO
by the combined sol-gel and solid-state method, and the addition of tin powder
together with activated carbon, is expected to increase the specific capacity
of the anode material. The tin powder compositions in this research were 5wt%, 7.5wt% and
12.5wt%. Further, to investigate the influence of activated carbon, 5wt%,
15wt%, and 25wt% activated carbon were added, while the composition of Sn was
kept at 7.5wt%. XRD, SEM and BET surface area measurements was performed to
characterize the morphology and structure of the samples. The performance of
the battery was analyzed using EIS, CV and CD. The results show that TiO2
rutile was present in the LTO samples, with peak rutile decreasing
significantly with the addition of carbon. More disperse particle morphology
was obtained by the addition of activated carbon. The LTO/Sn anode material
exhibits excellent reversible capacities of 191.1 mAh/g at 12.5wt% tin.
Additionally, the LTO/Sn@C has the highest specific-capacity at 270.2 mAh/g,
with a composition of 5wt% carbon and 7.5wt% Sn. The results show that LTO/Sn@C
is a potential anode material for the future. |
