A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among the top-performing sodium battery materials ever reported.
Great response, people just love to parrot easy dismissals without looking and the sheer magnitude on innovation and commercialisation going on in this sector
Well all those graphs show is that the cost of batteries has gone down and that as a result electric cars contain more batteries and therefore more range. It doesn’t actually show that the individual battery capacity has increased.
The third graph that indicates battery performance vs battery chemistry doesn’t really show incremental improvement it just shows general improvement but there’s plenty of battery chemistries that are worse than pre-existing ones.
It doesn’t really dispute it, though. Lithium-ion has seen a lot of improvement, yes, because it’s already a giant industry; other battery chemistries have a hard time breaking through because they require entirely different processes to manufacture.
I’m still rooting for it, but it’s not really the same thing.
This too is false, great progress has been made on for instance solid state batteries.
Some progress is being made, but it hasn’t seen large-scale adoption yet. Which is the point, as I read it.
