Ann: Altech - Breakthrough Silicon Alumina Coating Development, page-335

Was just thinking about this last night - noting Tesla's shift to LFP chemistry & the lower energy density of LFP vs NCA/NCM my thoughts immediately turned to this technology.
I had time to watch Jordan Giesige's video on this from The Limiting Factor linked below & if you haven't yet, it's worth a look as he explains very clearly that LFP has lower shorter term energy density, however because the battery cycle life is many times longer than NCA & capacity deterioration is constant over this long term, by about 400-600 cycles, LFP will in fact have better energy density than NCA after this point in time.


Naturally, my immediate thoughts were what would happen if the lower 20-30% energy density was able to be addressed with an anode side technology.
And then I find this interview with Iggy.
I'll drop Jordan an email as I think it would be great if he did a video on HPA coating technology & I'm sure he is well along that road as nothing gets by him.
This comparison chart is next level by the way...bottom right you can see LFP vs NCA is 21% (cell) & 30% (pack) lower energy density.
Altech's HPA coating technology claimed in this video, have just corrected that on the anode side which will bring iron/phosphate battery chemistry in line with where the best NCA battery chemistry is today, with respect to energy density.
Also important to note is that Jeff Dahn has indicated that 5,000 cycles is getting close to the million mile battery mark. The LFP chemistry appears to be getting close to this mark & if the anode side has a more durable solution (HPA coating) I think that the code that has been cracked is not just the increased energy density one, but the longevity one.
IOW imagine a headline that reads "Australian technology company cracks the code to enable million mile batteries"
Because that is what is sounds like it could lead to.
