University of California – Santa Cruz researchers show a novel ruthenium-based catalyst with markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix. The […]

A Tohoku University research team has developed new materials for supercapacitors with higher voltage and better stability than other materials. Supercapacitors are rechargeable energy storage devices with a broad range of applications, from machinery to smart meters. They offer many advantages over batteries, including faster charging and longer lifespans, but they are not so good […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Nagoya Institute of Technology scientists have found the desirable component for sodium-ion batteries (SIB), which could contribute to boost SIB performance such as speed of charge. While lithium-ion batteries are currently popular, it is expected that a new storage chemistry will be found soon, because lithium is not only expensive but limited in supply. […]

National Institute for Materials Science (NIMS) in Japan scientists have evaluated the economic efficiency of hydrogen production systems combining photovoltaic power generation and rechargeable batteries and estimated technology levels necessary for the systems to produce hydrogen at a globally competitive cost. The results obtained in this research may provide vital guidelines for pushing the intermittent […]

University of Manchester scientists have used a Nobel-prize winning chemistry technique on a mixture of metals to potentially reduce the cost of fuel cells used in electric cars and reduce harmful emissions from conventional vehicles. The researchers have translated a biological technique to reveal atomic scale chemistry in metal nanoparticles. These materials are one of […]
