Brookhaven National Laboratory scientists have synthesized a new cathode material from iron fluoride that surpasses the capacity limits of traditional lithium-ion batteries. Scientists are searching for ways to improve lithium-ion batteries, the most common type of battery found in home electronics and a promising solution for grid-scale energy storage. Increasing the energy density of lithium-ion […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Rice University engineers have developed a composite binder made primarily of fly ash, a byproduct of coal-fired power plants, that can replace Portland cement in concrete. According to Rice materials scientist Rouzbeh Shahsavari, who developed it with graduate student Sung Hoon Hwang the material is cementless and environmentally friendly. The fly ash binder does […]

A Korea Advanced Institute of Science and Technology (KAIST) research team has proposed a perovskite material that serves as a potential active material for highly efficient lead-free thin-film photovoltaic devices. This material is expected to lay the foundation to overcome previously known limitations of perovskite including its stability and toxicity issues. The KAIST research team […]

Swansea University scientists suggest that almost a third of the natural gas fueling UK homes and businesses could be replaced by hydrogen, a carbon free fuel, without requiring any changes to the nation’s boilers and ovens. The point is to cut back on carbon emissions. Over time such a move could cut UK carbon dioxide […]

Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers have combined silicon and perovskite materials making a tandem solar cell. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent. […]
