Hematite (Fe2O3) has a high capacity for anode material of lithium ion batteries (LIB). However, charge-discharge efficiency and capacity was fast fading. Also Fe2O3 has a created crack while charge-discharge cycle by volume expensive of particle. For solve this defect, we studied using the polymer at L-lysine. Which have positive charge by amine group. So add Citrate to the co-precipitation for Synthesis of iron oxide for negative surface. The effect of polymer was fixing the particle, and reducing volume change for electrochemical performance. In addition, expect improved electro conductivity that the polymer changed carbonization via heat-treatment. |
