Research and development of lithium and sodium ion battery technology based on metal organic frameworks (MOFs)

Lithium–ion batteries have become a vital component of the electronic industry due to their excellent performance, but with the development of the times, they have gradually revealed some shortcomings. Here, sodium–ion batteries have become a potential alternative to commercial lithium–ion batteries due to their abundant sodium reserves and safe and low-cost characteristics. As power sources for various civilian and military equipment, they have received widespread attention from the scientific research community. However, currently both lithium–ion batteries and sodium–ion batteries have encountered some problems like low electrode energy density and poor cycling efficiency. It is precisely these shortcomings that lead to the current application status of batteries being inadequate. Coincidentally, metal organic frameworks have the characteristics of high surface area, flexible chemical structure, and easy modification, and have been widely used in fields such as gas absorption, drug carriers, and sensors. Its derivatives have also been widely reported as electrode materials for batteries. This article reviews the various application status of metal organic frameworks and their derivatives (oxides, selenides, phosphides and porous carbon) in lithium–ion batteries and sodium–ion batteries. Finally, their limitations and future improvement methods were briefly explained.
