A review on the field patents and recent developments over the application of metal organic frameworks (MOFs) in supercapacitors

چکیده مقاله

Global energy demand and the seriousness in sustainable energy obligations along with a large amount of CO2 emission and rapid depletion of fossil fuels have diligently persuaded the researchers to promote eco-benign energy storage systems with high performance. High energy and power density, long cycling life, ultra-flexibility, environment friendly, light-weight with challenges of the benefits of industrial applications, safety, and reliability are currently considered in inventing efficient energy storage systems. Therefore, promoting and employing effective technologies to storing energy has widely become a development trend. Achieving that object is paved by developing batteries and supercapacitors (SCs) which are remarkably attracted enormous research interest and scientific reports. Supercapacitors are on a rapid and significant development path, with possessing desirable electrochemical benefits, including high power density, long cycle-life, rapid charge–discharge rate, and absolutely demanded commercial features. To understand the real performance of investigated supercapacitors, we considered the electrochemical output of applied SC systems. Actually, various types of electrode materials, electrolytes, have been significantly used to improve the electrochemical features in terms of specific capacitance, energy density, power density, and cycle life. Here, we focused on reviewing filed patents on application of MOFs in SCs and the recent improvements in employed components consisting of electrode and electrolyte in supercapacitive behavior. From the technical results, ZIF-series, UiO-66/67, MIL-based, MOF-74, MOF-5, Ni3(HITP)2, Cu3(HITP)2 are widely used in MOF-based SCs. Patents are costly to register and they are also extremely reliable documents that are remarkably reliable in comparison to articles. Because patents are seriously challenged scientifically and legally, they contain critical information that inventors must disclose in full detail. Compared to articles, patents are a truly reliable refereview opens a new prospective of MOF-based SCs for future electrochemical considering to provide higher performed devices.
