MOF electrochemical energy storage

Due to the unique properties of MOFs like highly tunable frameworks, huge specific surface areas, flexible chemical composition, flexible structures and a large volume of pores, they are being used to design the electrode materials for electrochemical energy storage devices.

Electrochemical energy storage (EES) systems demand electrode materials with high power density, energy density, and long cycle life. Metal-organic frameworks (MOFs) are promising electrode materials, while new MOFs with high conductivity, high stability, and abundant redox-reactive sites are demanded to meet the growing needs of EES.

MOFs have become very promising materials for enhanced energy conversion and storage because of their large surface areas, adjustable designs, and remarkable porosity. On the other hand, their actual use depends on the crucial factor of stability. The stability of MOFs for energy storage and conversion is represented in Table 2.

Indeed, opportunities and challenges coexist. There is still a long way to go before MOF-based materials achieve real practical applications in energy storage and conversion. With continuous research efforts, MOF-based materials have achieved so far immense advances in structural design and their applications, which are truly inspiring.

Metal–organic frameworks (MOFs) have emerged as desirable cross-functional platforms for electrochemical and photochemical energy conversion and storage (ECS) systems owing to their highly ordered and tunable compositions and structures.

Therefore, we believe that MOF-based materials, through the mutual promotion of rational design, structural regulation, and theoretical exploration, will present a bright prospect for energy storage and conversion applications.
