Titanium dioxide is a promising candidate to be used as anode material for lithium-ion batteries. It has some notable polymorphs such as rutile and anatase, etc. Although several studies revealed that one type of polymorph is better than other polymorphs, comparison between different polymorphs using same synthesis method is still unclear. This research discuss about electrochemical performance between 2 polymorphs of rutile and anatase synthesized by using sol-gel method followed by calcination process. The temperature for calcination process for rutile and anatase polymorps are 480 °C for 8 hours and 850 °C for 6 hours respectively. The synthesis of both rutile and anatase polymorphs has been a success with high purity and no impurity peak shown by XRD result. In this research, a sample of commercial TiO2 is used to make a coin cell battery to compare the performance between other samples. The electrochemical performances are examined by CV, CD and EIS.
