Solar, battery storage in airport electrification
Swedish researchers have analyzed the impact of electric aviation and electric vehicle (EV) charging on the power system at Visby Airport. They have discovered that on-site solar panels and battery storage could significantly reduce grid stress, and have proposed a novel approach to battery operation.
Novel technique to recover 100% of silver from CIGS solar cells
Swedish researchers have developed a method to recycle valuable metals from flexible thin film copper-indium-gallium-diselenide (CIGS) solar cells under mild leaching conditions. They showed that 100% of silver and 85% of indium can be recovered after 24 hours of leaching at room temperature using two moles of nitric acid.
New, powerful way to make micro supercapacitors
Swedish researchers have developed a novel way to manufacture micro supercapacitors, also known as system-on-a-chip, so they are compatible with other components in system circuits and can be easily tailored for different uses.
‘Massless’ battery breakthrough for lightweight EVs
A new type of carbon fiber and electrolyte matrix stunned scientists when they tested its properties. Their ‘structural’ battery could be used in electric vehicles and could even address the weight problems that bedevil devices planned for electric-powered flight.
New aluminum batteries for renewables storage
The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.
Swedish researchers develop ultra-fast hydrogen leak detector
The discovery could provide a great leap forward in the feasibility of using hydrogen-powered cars to curb global transport emissions.
