A bimetallic Zn-Co-ZIF derived from metal organic framework was successfully synthesized via simple co-precipitation method. The as-synthesized bimetallic MOF powder was then pyrolyzed at 600 degrees C, 700 degrees C, 800 degrees C, and 900 degrees C in N-2 atmosphere, which changed the morphology and structure of the final product evidenced from field emission scanning electron microscopy and X-ray diffraction. The electrochemical results revealed that the change in elemental composition affected the specific capacity, cycling stability, and rate capability for each sample. The galvanostatic charge-discharge results showed that C600 achieved the highest specific capacity and rate capability compared to other samples heated at higher temperatures. On the other hand, C900, the sample heated at the highest temperature exhibited the best capacity retention after 50 cycles at 78% after the initial discharge whilst providing the lowest reversible discharge capacity at 45 mAh g(-1).
