Tap Density

LiFePO4/C materials were synthesized by spray-drying using FePO4·2H2O, LiOH·H2O as raw materials, glucose as reducing agent and conductive additive. The morphology, structure and electrochemical properties of the LiFePO4/C were tested and analyzed. The morphology of the LiFePO4/C was biconcave and round looked similar to red blood cells, the tap density of the material up to 1.45g/cm3. The electrochemical performance of the material was excellent. The LiFePO4/C had an initial discharge specific capacity of 161.8mAh/g at rate of 0.1C and its specific capacities were 148.7, 120.9mAh/g at rates of 1, 5C rate, respectively. The discharge capacity remained at 95.8%, 81.7% after 500, 1000 cycles respectively at rate of 5C.

Phase And Chemical Composition

Lithium-ion batteries have been a substantial power source for most electrical devices nowadays. Performance optimization for anode of lithium-ion batteries (LIBs) can be conducted by adding ZnO through sol-gel solid-state reaction. In this research, the Li4Ti5O12 (LTO) used was synthesized through sol-gel solid-state process and directly added with ZnO-nanorods obtained from aging and annealing process. LTO-ZnO obtained was characterized to determine the main phase and chemical composition by XRD and SEM-EDS respectively. Electrochemical performance of LTO-ZnO was tested by EIS, CV, and CD. ZnO-nanorods characterization with SEM-EDS results shows that the ZnO inside the LTO dispersed homogeneously. Characterization using XRD revealed that the ZnO successfully enter the LTO with the variation of amount of 4, 7, and 10 wt % of ZnO. Electric conductivity test shows improvement at an optimum addition amount of ZnO at 4 wt%, although BET result shows at the optimum amount of surface area with 96.459 m2/g. Electrochemical performance result shows optimum performance in ZnO at 4 wt% for its ability to withstand EIS test at 20C compared to 7 wt% and 10 wt%. Also, capacity of 4 wt% added is 150.8 mAh/g compared to 7 wt% with 134.1 mAh/g and 10 wt% with 118.3 mAh/g.
