Metal-Organic Frameworks and Derivative Metal Oxides for Advanced Lithium and Sodium Ion Batteries

High energy density lithium and sodium ion batteries have attracted much attention because they are crucial to the power supply of future portable electronic devices, electric automobiles and large-scale energy storage power plants. At present, the research development of commercial lithium-ion batteries and sodium-ion batteries are facing some technical bottlenecks, such as low energy density and weak charging and discharging capacity, which unable to meet market demand. Metal organic frameworks (MOFs) and their derived metal oxides, which possessing unique structure and high specific surface area, are considered as new electrode materials for electrochemical energy storage devices to meet the requirements of high energy lithium and sodium ion batteries. In this paper, the recent progress of metal-organic frameworks and their derived metal oxides work as electrode materials for lithium and sodium ion batteries was reviewed. Meanwhile, the challenges of MOFs and their derived metal oxides in future applications and possible development tendency were pointed out.
