...Iron is one of the most abundant metals on Earth, and the most produced. It has an #energydensity of about 11.3 kilowatt-hours per liter—better than gasoline. Burning iron powder produces heat that can be used directly or converted into electricity by a steam turbine, leaving behind iron oxide, or rust...

The early #eevblog episodes on battery technology and capacity never really grov old: physics, chemistry and the many performance parameters is as relevant now as it was 12y back. And it’ll continue to be so, don’t ever believe people telling stories about ‘magic batteries that solves everything’ 🦄😂

Anyone looking to design battery powered circuits, should watch these episodes, they’re really the ‘batteries 101’.
I’ve worked with electronics my entire career and these episodes were still an eye opener to me on certain topics 🙂

Highly recommended 🤓

This is a visual explanation why mass produced batteries still have a long way to go before becoming competitive with gasoline or diesel when we measure the energy density. This doesn't mean we should keep using oil. Source: IEEE Spectrum
