- himata4113lots of exciting battery developments in general, especially if donut labs by some miracle is not a fraud.it was a bit worrying as there was somewhat of a stagnation in battery chemistry, but having non toxic/dangerous battery storage is going to make off-griding so much more attractive.technically speaking, if every household had solar panels and batteries it would not only be cheaper than the grid it would also have complete independence from oil fluctuations, weather disasters and centralization.now if you combine that with electric cars that charge off your off-grid system and transition to eletric appliances instead of something like gas the benefits keep stacking all while being pretty much net neutral post manufacturing.
- Animats"CATL’s “Naxtra” sodium-ion batteries achieve an energy density of up to 175 Wh/kg, the company said, putting it on par with lithium iron phosphate (LFP) batteries."Useful, but not a "breakthrough" in energy density. More like another good low-end option.
- GrimblewaldBYD / Denza z9 gt claim 10-70% in 5 mins, 97% in 9 mins. With a range of ~1000km this seems to crush these results? I don't know enough about this space to know if I am missing something here, but would love to know because something about this feels more exciting than i think i am grasping. anyone know?
- thescriptkiddienote that the quoted 170Wh/kg is about the same as currently available LiFePO4 cells and half that of the best available NMC cells
- WarmWashI don't know what chemistry exactly these cells are using, but in sodium-ion batteries, prussian blue analogs as they are called are common anode materials. Overcharging these cells can lead to a release of hydrogen cyanide gas, notoriously known as Zyklon B.It has damped my enthusiasm for perusing it as a potential future home energy storage solution.
- cyberaxJust remember, the US Na-Ion battery startup died last year with _products_ _in_ _warehouses_ just because it couldn't get a UL certification. All it needed was a bridge loan.And the government did nothing.
- readthenotes1Another better battery bulletin
- dborehamPeople posting claims about EV charging time should be required to also post the size of cable required. And the grid capacity needed to provide their fast charging at a typical 8-bay charging site.
