Abstract

Lithium-Ion batteries are one of the effective media for storing energy. This battery continues to be investigated further to increase the efficiency and power of the cell. LTO anode is a material that is being developed as a substitute for graphite anode. LTO or lithium titanate has several advantages, such as the zero-strain characteristic, that is, there is no change in volume during charge and discharge. The LTO synthesis was carried out using a solid-state method with a mechanochemical process and sintering at a temperature of 850 °C for 6 hours. Zn content added is 3 wt.%, 7 wt.% and 11 wt.%. and graphite at 3 wt.%. Addition of Zn doping to LTO increases the electronic conductivity and specific capacity of the battery. LTO-Graphite/Zn composites were characterized using XRD and SEM-EDS. The battery performance test is carried out using EIS, CV, and CD testing. The EIS test results obtained the highest conductivity value on 3 % LTO-graphite / Zn composites. The highest specific capacity CV test results obtained LTO-graphite/Zn 11 % of 154.3 mAH / g. The highest charge-discharge capacity is achieved by LTO-graphite/Zn 11 % in the current rates of 0.5 C to 15C.
