    One of the most finest materials for lithium ion battery nowadays is lithium iron phosphate or LiFePO4. Lithium iron phosphate was synthesized with solid state reaction method by optimizing the variable of material and temperature. The variable for calcination temperatures were 700oC, 800oC, and 900oC while the basic materials as Fe sources were Fe2O3 and FeSO4. Particles morphologies and quantity of crystal were investigated in details by X-ray diffraction analysis XRD. XRD imaging showed diffraction of nanoparticles LiFePO4 with crystal quantity 40,4% (800oC) and 59,1% (900oC) of materials Fe2O3,which the most quantity from other samples. Thus, chatode materials were made from LiFePO4 that synthesized at calcination temperatures 800oC and 900oC. The best performance of lithium ion battery was showed in cathode materials from calcinated temperatures at 900oC. This battery had 9,97 mAh/g charging capacity and 1,44 mAh/h discharging capacity, however these results had lower capacity from theoritical capacity. In conclusion the material chatode from LiFePO4 that had been synthesized was not suitable for Lithium Ion Battery, thus need more improvement in optimizing the process condition for ideal chatode material.
