Indian scientists have developed a low-cost electrocatalyst based on iron, manganese and N-doped carbon derived from fish gills (Fe/Mn/N-FGC) to increase the performance of a homemade rechargeable zinc-air battery. The Fe/Mn/N-FGC cathode-based battery achieved open-circuit voltage of 1.41 V and a large power density of 220 mW/cm2 at 260 mA/cm2 current density - compared to 1.40 V and 158 mW/cm2 for a commercial platinum/carbon-based battery - with almost stable charge-discharge voltage plateaus at high current density.From pv magazine India Indian scientists have synthesized a bio-inspired electrocatalyst ...Den vollständigen Artikel lesen ...
