New material could help improve electric vehicles in the future

Chemists develop new material that combines qualities of batteries and supercapacitors Chemists from Northwestern University have developed a powerful new material that could have major benefits for electric vehicles. Currently, electric vehicles rely heavily on a complicated system of batteries and supercapacitors that allow them to operate and increases the energy they have access to, allowing them to operate for longer periods of time. The new material developed by chemists combines the quality of supercapacitors and batteries. As such, the material can be used to replace the complex systems used…

Perovskite cells help make solar energy less expensive

Emerging technology is helping lower the cost of solar power New technology could mean a major decrease in the cost of solar energy and make this form of clean power a more attractive investment. A new study from the Northwestern University and the Department of Energy suggests that perovskite cells show major promise for the solar power sector. The study notes that these cells can repay their energy costs more than 10 times faster than conventional solar cells, which are typically based on silicon. Perovskite cells are also somewhat more…

Imperfect graphene could lead to better fuel cells

Researchers see great deal of promise in imperfect graphene and its uses in fuel cells Researchers from Northwestern University, along with those from other organizations, have found that imperfect graphene could be used to improve hydrogen fuel cells. Graphene is often used in a honeycomb structure, which allows for a great deal of durability and conductivity. This material naturally has tiny holes in it, which may be of benefit to fuel cells as these holes would allow for the development of a proton-selective membrane. The imperfections of graphene may open…

Researchers develop new stretchable lithium-ion battery

Hydrogen Fuel Cells - New Research

New lithium-ion battery could put criticism to rest Lithium-ion batteries have become a very popular renewable energy system, but have also been the subject of criticism over the past two years. These energy systems are widely used in electronic devices and, on a small scale, perform very well in these devices. Lithium-ion batteries are also widely used in electric vehicles, but have been criticized for their lack of efficiency and performance when compared to more traditional energy systems and even hydrogen fuel cells. Researchers from the Northwestern University and the…

New organic material capable of ferroelectricity

alternative energy white paper

Ferroelectricity property found in new class of organic materials A new group of organic materials developed by researchers from the Northwestern University in Illinois have shown that they have ferroelectric properties. Ferroelectricity refers to a phenomenon in which materials experience spontaneous electric polarization that can be manipulated through the application of an external electric field. This property is rare, but quite attractive because of how it may be used in electronics. The materials developed by researchers also have a good memory. These two features could make the materials revolutionary in…
