Cobalt-based metal-organic frameworks as functional materials for battery applications

In recent years, metal-organic frameworks (MOFs) have been widely used in various fields, especially in the field of electrochemical energy storage and conversion, because of their excellent properties. It is reported that Co-MOFs usually play the role of templates with other active components to improve the overall properties of materials. Pristine Co-MOFs have been widely used for battery applications because of their excellent performance as well as the simple fabrication process, which can eliminate concerns regarding poorly controlled pyrolysis. Herein, for a further specific summary of particular applications of Co-MOFs, we will mainly review the relative applications of Co-MOFs in lithium-ion batteries, sodium-ion batteries, potassium-ion batteries, lithium-sulfur batteries and metal-air batteries. In this paper, the applications of pristine Co-based MOFs are reviewed in detail, which can provide a reference for future work.
