Abstract

Lithium titanate (Li4Ti5O12)/LTO is a promising anode to produce Lithium Ion Battery with high power. In addition, silicon has a theoretical capacity of 3590 mAh g-1 to phase Li15Si4 at room temperature. But lacked by the large volume expansion during cycling and shorten the cycle life of the battery, SEI layer instability due to a material change Si, and low electrical conductivity. However, nano particles of Si has higher specific capacity and storage capacity are better when compared with Si particles that has a micro size. In this research Li4Ti5O12 and nano silicon has a good synergy in the capacity of battery as a composite. This research was synthesized by using solid state methods. XRD and TEM was performed to identify the phase, morphology of LTO powder. Effect of solid-state route and ball mill at Li4T5O12 powder produced has an average particle size of 225.95?nm and the degree of crystallinity of 67%. Cyclic voltammetry (CV), Electro-impedance spectroscopy (EIS), and charge discharge (CD) test used to examine the battery performance In the battery fabrication process is done by adding the active material to the silicon nano variation of 5%, 10% and 15% in wt. The additions of active material in order to raise the capacity of the battery. Capacity owned by LTO-nSi5 of 191.58 mAh/g, LTO-nSi10 197.5 mAh/g, and LTO-nSi15 195.6 mAh/g. LTO-nSi10 has the greatest conductivity values compared LTO-nSi5 and LTO-nSi15. LTO-nSi15 samples showed the greatest resistivity values, indicating that the conductivity values obtained at each addition of the lower grade of silicon nano.
