The LiCoO2 is widely used in LIBs as cathode material due to its excellent cycling performance, great working potential, and high specific capacity. Porous material is considered as most important in almost every field and it has several uses like, including energy storage, catalysts, adsorption, etc. Porous LiCoO2 prepared by cobalt base MOF (Metal-organic frameworks) material are very stable and shows the highest rate capacity with 96.4% capacity retention up to the 100 cycles and reversible capacity of 106.5 mAh/g while for the commercial . The capacity of commercial LiCoO2 the capacity rapidly declined due to increase in the density of current and its capacity decreased to almost zero when the current density reached 6C as seen in Figure 5.
