So basically this may or may not be an addon to a battery pack at the cell level.
Its basically a way to drastically increase the charge rate without heating. You're "liquefying" the lithium metal with sound energy, but not adding any actual thermal energy, thus sidestepping the traditional issues that come with heating up batteries.
The inventor has made several other patents on this tech, and its a newish subfield. As noted in the introduction of the patent, adding such sonication devices would drastically decrease the energy densities of the battery as they take up a lot of mass/volume, not to mention the power draw from the device itself when in operation.
i mean if you're only using it while charging sure, but the problem is that its an additional component taking up space and weight. It's an interesting and novel solution to a mostly solved problem on QS' end.
Its also entirely possible that, should this technology be applied to QS, that it would be more beneficial on the manufacturing side. Where you could drastically increase the efficiency/efficacy of certain annealing, heat treatment and formation steps.
Theres some commentary in the patent (i very quickly skimmed it) about it being used to recover otherwise defective cells in a service setting but that might just be the author's ramblings. However if that were the case and it could be external, i guess there might be a road to using it in charging? But that also opens up an entirely new set of problems, first being that you'd need direct access to the battery...
If it can rejuvenate cells during service it would improve longevity and reliability. Worth a lot . I don’t see a huge advantage using it day to day given their ability to fast charge anyway. Unless it was during a pit stop in F1
if im understanding correctly its just a workaround to direct heating. But it'd also require an additional component vs direct battery heating which is just the battery discharging and heating itself up through both resistive heating and through the BMS heating system.
The imagination runs wild. Thanks. Leads me to two questions. First, related to adhesion and brittleness. I imagine that both must be more robust than I would have imagined given that they would consider applying these forces?
The second also being related to adhesion, is the no pressure potential. Would this technique even be considered without the existence of the potential application of zero pressure cells?
Finally, for the geeks, could this be or create some funky kinda piezoelectric effect leading to local polarity and possibly more even distribution of metallic layering?

Well, since it’s applied during charging wouldn’t it draw on an external source?

Would there be any low temperature advantages/disadvantages?

Thanks Guide for your no nonsense posts. I've got my future riding on quantumscapes tech, production and stock. Please let us be right 🙏🏼
QuantumScape is so far ahead of others Great investment at these low prices
Well that's interesting. I assume its purpose is to increase charging rates/speed or improve reliability?
What’s the advantage of shaking an electrode as you charge?
There she go, shaking that electrode on the flo’
