MIT researchers have for the first time developed a supercapacitor that uses no conductive carbon at all. The new supercapacitors could potentially produce more power than existing versions of this technology. Energy storage devices called supercapacitors have become a hot area of research, in part because they can be charged rapidly and deliver intense bursts […]

Researchers from the Solar Energy Institute at the Universidad Politécnica de Madrid (UPM) are developing a new energy storage system in which the entry energy, either from solar energy or surplus electricity from a renewable power generation, is stored in the form of heat in molten silicon at very high temperature, around 1400° C. The […]

A Ulsan National Institute of Science and Technology (UNIST) team of researchers claims to have made yet another step towards finding a solution to accelerate the commercialization of silicon anode for lithium-ion batteries. A new approach developed by a team of researchers, led by Prof. Jaephil Cho (School of Energy and Chemical Engineering) could hold […]

The National Institute for Materials Science (NIMS) researchers have developed an anode material for lithium-ion rechargeable batteries by forming nanoparticles made of silicon metal composites on metal substrates. The resulting anode material has a high capacity – almost twice as high as conventional materials – and a long cycling life. The results could lead to […]

Penn State Materials Research Institute scientists have developed a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. The team’s results have been […]
