Templated synthesis of nano-LiCoO2 cathode for lithium-Ion batteries with enhanced rate capability

In this work, the nanosized lithium cobalt oxide (LiCoO2) is synthesized by a high-temperature solid-state reaction method using (Zeolitic Imidazolate Framework-67) as self-sacrificial template. By compared to commercial LiCoO2, the nano LiCoO2 demonstrates high porosity, boosted electrochemical behavior and enhanced specific capacity. As the cathode for lithium ions battery, it delivers a high capacity of 112.3 mAh g(-1) over 300 cycles between 3 and 4.5 Vat 0.5C. Even at 3C, the specific capacity is 137.5 mAh g(-1), which is 62% higher than that of commercial LiCoO2 (84.9 mAh g(-1)).
