N2 - Li4Ti5O12 is one of promising materials for lithium ion battery anode material. Li4Ti5O12 is a zero strain material, where the material does not undergo volume expansion during the charge/discharge process. However, Li4Ti5O12 has a relatively low theoretical capacity (175 mAh/g). Modifying Li4Ti5O12 material is necessary to improve its electrochemical performance. Method that can be done is by combining Li4Ti5O12 with tin (Sn), which has a very high theoretical capacity (994 mAh/g). However, Sn has very large volume expansion problems as well as pulverization phenomena during its charge/discharge cycle. Therefore, graphite is used to prevent the excessive volume expansion of Sn. Graphite has the effect of stress-relieving on Sn, so it can inhibit its volume expansion during the charge/discharge cycle. In this study, composite synthesis of LTO/Sn-graphite was carried out by solid state method. To determine the effect of Sn content on these composites, Sn variations were carried out at 5 wt.%, 10 wt.%, and 15 wt.%. The results of this study shown that sample with 10 wt.% Sn content has the best discharge capacity and working potential value. Sample with 5 wt.% Sn content has the best retention capability. Sample with 10 wt.% Sn content has the least resistance value.
