Common materials that been used as a cathode material is LiCoO2 (lithium-cobalt oxide), but cobalt is a heavy and toxic material, expensive, and has poor thermal stability. Recently LiFePO4 has been developed as an alternative material for cathode thanks to its high thermal stability, nontoxicity, good charge/discharge capabilities and cheap cost. The length of electrode affects battery capacity. The wider the electrode surface area, the greater the capacity of the battery is. This research has created a lithium-ion battery cell with LiFePO4 as cathode materials and it has been tested to look at the influence of the electrode surface area against the battery characteristics by way of charge-discharge method. Based on the test that’s been done, result showed that the battery cell with electrode surface area of (22 x 2) cm 2 has the most capacity and effic...
