How iron-air batteries could fill gaps in renewable energy

Cycle life is a

Sounds tricky. Bypass the bridge rectifier, then put some tool batts in series until I get 40-odd VDC? A couple nominal 18 V batteries might do it.

The 60V Dewalts will give you 40-60 volts.

Drip-feeding results sounds scammy to me. If the technology is genuinely new, I’d have thought they would have patented it and then they could say what the technology was. In any case, once it is commercially released people can dismantle one and find out.

And ... the results are apparently in... and it seems to be a scam/fraud.

Donut Lab's 'solid-state' battery exposed as regular li-ion in damning investigation

A detailed investigation confirms Donut Lab's 'solid-state' battery is actually a lithium-ion cell, with over 20 experts and electrochemical data proving the claims were false.

The supposed solid-state battery that uses no Lithium... is a lithium ion battery. All the results observed from testing seem to make sense that it is Li-ion.

So, on to the next new remarkable claims.

Hmm, somebody needs to go to prison for fraud on the investors who were tricked.

But I still hope this real Na ion battery using ferrocyanide may have legs. It would be great to get away from dependence on mainly Chinese Li. The problem seems to be is the size of the cation. Li+ is smaller than a helium atom. Anything from the next row of the periodic table is going to be a lot bigger - and thus harder to fit reversibly into the lattice of an anode material.
