A University of Houston professor is reporting on a new type of solar energy harvesting system called thermophotovoltaics (STPV) that breaks the efficiency record of all existing technologies. And no less important, it clears the way to use solar power 24/7. Photovoltaic cells which convert sunlight directly into energy have made much progress. Yet with […]

When overheated Lithium-ion (Li-ion) batteries are prone to catching fire or even exploding. Yet they are used to power everything from smart watches to electric vehicles, thanks to the large amounts of energy they can store in small spaces. A recent research paper published in American Chemical Society’ Nano Letters offers a possible solution with […]

University of Queensland researchers report studying ancient ocean floors could help us discover the minerals needed to produce electric cars and solar panels. The researchers led a collaborative study that examined the remnants of ocean floors in eastern Australia and central Asia and applied a method to date the age of calcite trapped inside. Dr. […]

A research team led out of Tianjin University replaced the traditional graphite anode in a lithium-ion battery with a bumpy carbon-based material, which maintains its rechargeable storage capacity down to -31 F. When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion […]

A Tohoku University research team has developed liquid-sulfur/sulfide composite cathodes that enable high-rate magnesium batteries. Magnesium rechargeable batteries show immense promise for a greener future because of their energy density, safety, and cost. But the lack of high-performance cathode materials has impeded their development. Magnesium rechargeable batteries (MRBs), where high-capacity Mg metal is used as […]
