New rechargeable aqueous battery challenges Lithium-ion dominance
22-Aug-2019
A new rechargeable high voltage manganese dioxide zinc battery, exceeding the 2 V barrier in aqueous zinc chemistry, is the latest invention by City College of New York researchers. With a voltage of 2.45-2.8V, the alkaline MnO2|Zn battery, developed by Dr. Gautam G. Yadav and his group in the ...
A smart safe rechargeable zinc ion battery based on sol-gel transition electrolytes
23-Jul-2018
The thermal runaway issue has been a long-standing obstacle impeding the development of high energy density and high power delivery batteries. These batteries would generate a lot of heat in ultrafast charge/discharge process or hazardous conditions, such as overcharging and short-circuit. To ...
Quantum Dot White LEDs Achieve Record Efficiency
16-Jul-2018
Researchers have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt. Luminous efficiency is a measure of how well a light source uses power to generate light. With further development, the new LEDs could reach ...
Metal-organic compounds produces new class of glass
13-Mar-2018
Lightning and volcanos both produce glass, and humans have been making glass from silicon dioxide since prehistory. Industrialization brought us boron-based glasses, polymer glasses and metallic glasses, but now an international team of researchers has developed a new family of glass based on ...
Promising sensors for submarines, mines and spacecraft
14-Nov-2017
Researchers from the Physics Department of Moscow State University and their colleagues have discovered a mechanism that allows gas sensors, based on nanocrystalline metal oxides, to work at room temperature. This invention will raise the efficiency of environmental monitoring at nuclear power ...
Novel catalyst for rechargeable metal-air batteries
27-Oct-2017
Research in lithium-ion batteries has opened up a plethora of possibilities in the development of next-generation batteries. In particular, the metal-air batteries with significantly greater energy density close to that of gasoline per kilogram, has recently been acknowledged and invested by ...
When a porous solid retains its properties in liquid form
12-Oct-2017
Known for their exceptional porosity that enables the trapping or transport of molecules, metal-organic frameworks (MOFs) take the form of a powder, which makes them difficult to format. For the first time, an international team led by scientists from the Institut de recherche de Chimie Paris, ...
Advanced lithium-ion and metal-air batteries developed
21-Sep-2017
University of Central Florida Assistant Professor Yang Yang's research group has developed two promising energy storage technologies in its work with sustainable energy systems. Yang sees revolutionary systems that can produce and store energy inexpensively and efficiently as a potential solution ...
A more sustainable way to refine metals
08-Jun-2017
A team of chemists in Canada has developed a way to process metals without using toxic solvents and reagents. The system, which also consumes far less energy than conventional techniques, could greatly shrink the environmental impact of producing metals from raw materials or from post-consumer ...
Printed, flexible and rechargeable battery can power wearable sensors
29-May-2017
Nanoengineers at the University of California San Diego have developed the first printed battery that is flexible, stretchable and rechargeable. The zinc batteries could be used to power everything from wearable sensors to solar cells and other kinds of electronics. The researchers made the ...
