This is a most excellent place for technology news and articles.
So, a guy with a PHD thesis on solid state batteries is saying that these results are not as promised
This result matches largely with the startups claims. Given what they tested, cycle times and aging are largely unknown and thermal management requirements are quite high for fast charging, this results in problems with packing, aging and charge losses. Its a nice first step, but there is a ways to go until market readiness IMHO.
I'm something of an electrical engineer but not a battery expert by any means.
I think the "it retains 98% charge" quote might be misleading. Thats true for the capacity (in Ah), but not for the energy (in Wh). The report shows this clearly in the tables:
Efficiency is about 83% if my math is right (which is still good).
Last paragraph
Under the specified test conditions, the cell was successfully charged at 5C for more than 9 minutes, and 100 % of the charged capacity was available during the subsequent discharge. The cell was also successfully charged at 11C for more than 3 minutes, with 98.4–99.6 % of the charged capacity available after a full charge.
Please don't make the post link go straight to a file.
Weirds me out when I think I'm going to a website and suddenly it's asking where I want to download to.
Sorry but there is only a PDF of the results, ill go make a website just so you and the 8 other people aren't weirded out by a PDF...
Man if this is actually real it wi be crazy. I'm waiting for some crazy limitation to be discovered.
Next week they are releasing more testing This is from a legitimate testing company in Poland
The report is from an independant institute from Finland, not Poland:
VTT Technical Research Centre of Finland Ltd
oops!!
