Synthesis of LiFePO4/CNT composite with various calcination times as a battery cathode material has been successfully carried out. LiFePO4 synthesis was obtained by the sol-gel method and the addition of CNT was carried out by the doctor blade method. The effect of variations in calcination time and the addition of CNT to the synthesis results were observed. Observations using SEM-EDS showed successful synthesis with a homogeneous surface morphology with the appropriate element content. The XRD results also showed standardcompliant nano crystalline peaks with increasing crystallinity by addition of CNT and duration of calcination. In addition, the conductivity also increased in the presence of CNT and the longer the calcination time. This shows that the resulting LiFePO4/CNT has the potential as a battery cathode material.
