Calcium metal battery capable of more than 500 cycles
Researchers at Tohoku University in Japan have developed a prototype calcium battery with a long cycle life of more than 500 charge-discharge cycles. The battery was developed using a hydride-based electrolyte and copper sulfide nanoparticle/carbon composite cathode.
Australian startup reveals 20-layer battery cell based on semi-solid li-sulfur technology
Brisbane-based Li-S Energy has developed a 20-layer battery cell utilizing semi-solid state lithium sulfur battery technology. The company claims the new cell displays nearly double the gravimetric energy density and a comparable volumetric energy density to lithium-ion cells.
Dutch regulator warns of EMC issues, hacking risks for solar inverters
Most solar inverters in the Netherlands fail electromagnetic compatibility (EMC) requirements, posing interference risks and raising the threat of hacking, says the National Inspectorate for Digital Infrastructure (RDI).
Novel design for inverted all-perovskite bilayer solar cells with 24.83% efficiency
An international research team has crafted an innovative solar cell design. By employing a top absorber consisting of methylammonium lead iodide (MAPbI3), a lead-halide perovskite, and a bottom absorber composed of FA0.5MA0.5Pb0.5Sn0.5I3, a perovskite material, the cell maximizes light absorption across a broad spectrum.
