A University of Houston research team is trying to solve the dendrite problem by investigating how these structures grow on batteries. Dendrites are spiky structures that accumulate on the batteries’ anodes. These structures reduce the life of the batteries, hinder their ability to hold a charge and can short-circuit machines potentially causing safety hazards like […]

Disorder Engineered Inorganic Nanocrystal Solar Cells
March 30, 2022 | Leave a Comment
Researchers at The Institute of Photonic Sciences report on a novel disorder-engineering technique for inorganic solar cells that achieves a record-breaking power conversion efficiency. Now displayed over roof tops and in solar farms, silicon-based solar cells are, so far, one of the most efficient systems in generating electricity from sunlight, but their fabrication can be […]

Cornell University researchers have found a nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used. The new discovery could accelerate the widespread use of hydrogen fuel cells, which hold great promise as efficient, clean energy sources for vehicles […]

A research team at the Massachusetts Institute of Technology (MIT) have now shown for the first time that light can be used to increase the mobility of ions and improve the performance of such devices. Lithium-ion batteries, fuel cells and many other devices depend on the high mobility of ions in order to work properly. […]

Progress For Identifying New Electrocatalysts
March 23, 2022 | Leave a Comment
A Ruhr-University Bochum team has developed an efficient method for identifying promising candidates in the myriad of possible materials. Efficient electrocatalysts, which are needed for the production of green hydrogen, for example, are hidden in materials composed of five or more elements. To this end, the researchers combined experiments and simulation. High entropy alloys (HEAs) […]
