Solid oxide fuel cells hold great potential among fuel cell technologies due to their high heat and power efficiency, long-term stability, fuel flexibility, and relatively low cost. Glass and glass-ceramics are of great interest as sealants in SOFCs, and today’s CTT looks at a few recent studies on glass-based sealants.

In concentrated solar power systems, higher operating temperature leads to greater efficiency—if the thermal energy is properly managed. Heat exchangers are one option for thermal management, and researchers in Switzerland and Italy explored designing ceramic lattice structures for use in such devices.

Lithium iron phosphate is a widely used cobalt-free cathode material for lithium-ion batteries. It is known to experience certain kinds of defects in its crystal structure, however, and a recent study led by researchers at the Skolkovo Institute of Science and Technology explores the existence of hydroxyl groups in phosphorus vacancies.

One of the main challenges to commercializing solid-state batteries is stabilizing the interface between the solid electrolyte and electrodes. In a recent paper, researchers from the University of Illinois Urbana–Champaign and Xerion Advanced Battery Corporation look at the role interface morphology and crystallography play in solid-state battery performance.

As renewable energy technologies become more widely deployed, we need a way to store all of the generated energy. Two researchers from Chalmers University of Technology in Sweden explored creating a cement capable of storing energy, an ability that would allow future buildings to essentially serve as giant batteries.

Perovskite solar cells struggle with long-term reliability due to their love–hate relationship with the sun. Brown University researchers explored using self-assembled monolayers to “glue” interfaces within the cells and thus make the cells more efficient, stable, and reliable.

Determining oxidation stability of new MAX phases is a difficult and expensive process with current computational and experimental methods. Researchers at Texas A&M University designed a new machine-learning-based scheme for predicting the oxidation of MAX phases at high temperatures, allowing them to conduct studies that may otherwise take years to perform.
